Baghdad 2017 – tips for business visitors

Posted by

Following an initial meeting in Amsterdam in late 2016 we received an invitation in July from an Iraqi Oil company to visit Baghdad and discuss in more detail how OPC could assist them. As I had only just returned from a trip to Iran, and had been travelling a lot, I asked all qualified staff to form a queue if they wanted to go to Iraq.  Unfortunately the queue never formed! As all leaders need to do from time to time, I took it on the chin and booked myself onto the flight to Baghdad for the second week in August.

Here is a snapshot of my visit which hopefully will encourage others to investigate business opportunities in Iraq.

Flying into Baghdad

I travelled overnight from London to Baghdad via Istanbul arriving at 06:00 on the Monday.  Other than a 3 hour layover in Istanbul, and virtually no sleep, it was a relatively painless trip.

Visa Entry – get into the right queue

With the correct paperwork which is a paper/printed visa request supplied by the Ministry of Oil in my case, or any other Iraqi legal entity), a visa is issued on arrival. No photograph is needed, but US$82 (in cash, obviously) is to pay for it, and of course your passport.  There is a special queue/office for the visa application, separate to the passport check queue.  The visa is required first before the passport is stamped.  I found this out having queued for the passport control, only then to be redirected to the visa office queue…….

Get picked up at Baghdad International Airport

The airport and the surrounding few miles has very high security to stop anyone shooting at planes landing and taking off (which is encouraging!!)  However – that means the arrivals area is deserted apart from those authorised to meet visitors – so make sure you arrange this with your host in advance.

Get a lower level room in Baghdad hotel if you can

baghdadhotelMy hosts picked me up and drove me to the Babylon Hotel. This is a large very secure hotel with prison-like security. Steel gates that only open when the one behind is closed, sniffer dogs check for explosives, there is an engine check of a car and total car search, (which seems to be fairly standard everywhere) and then a personal search and airport security scanners of bags and person to get into hotel entrance.  No guns are allowed in the hotel, other than those with the security staff.  Since I didn’t have a gun, the security was relatively straightforward.  However, I was advised NOT to talk to anyone about my travel plans while at the hotel (didn’t talk to anyone except the waiters!) so no attack can be planned on you personally after leaving the hotel.  Once inside the hotel, it is extremely pleasant and the same as any other luxury hotel other than the electricity cutting out every now and then.  A lower floor hotel room therefore minimises the use of the lifts which get stuck when the electricity cuts out- only temporarily though!

Business meetings are thorough – be prepared

I had a couple of hours sleep before being picked up and meeting the oil company at the Oil Cultural Centre.   I met with around 20 of the oil company staff and made my presentation about the capabilities of OPC (if you’re interested in subsurface consultancy then check out our website!) Then we had lunch, which in true middle eastern tradition was plentiful food-wise.  Interestingly, there is Pepsi, but no Coke!  As in the film “The Art of Lying” “Pepsi, for when there is no Coke” applies here!  After lunch it was a question and answer session as to how OPC would go about increasing production from their oil field.  The electricity cut out every now and then necessitating the restarting of everything except my laptop!   It was a bit like other experiences I’ve had in the region in that you really need to have clear examples of how you have solved similar problems in the past.  You are a westerner and need to demonstrate that you understand the circumstances they have and can help them with a solution. I prepared a short document there and then to show what data we needed and what we could deliver which impressed and satisfied them.   The meeting finished with an obligatory photo (can you spot me?) and I got back into the car for trip back to the hotel.

Checkpoints on Oxford Street

checkpointWe took a more direct route back which meant we were stopped at a check point in the middle of Baghdad.  This is the area around Saddam Hussein’s former palace which used to be a thriving shopping area (the “Oxford Street of Baghdad”).  It has recently and frequently been targeted for car bombing so the road has check points at either end, which somewhat limits the appeal of the retail outlets.  Also there was a fairly long wait in the heat to clear the check point which of course has meant that the place gets targeted again by the “mad people” as there are loads of people waiting in the queue!  Eventually we got back to the hotel and I reviewed the meeting with my local representative and made action points for the teams back in London and Dubai.

After a long day I was finally alone to catch up on emails, have some dinner and a well-deserved beer.  Unfortunately the hotel had run out of beer – not even a non-alcoholic beer in this hotel!  I was advised to stay in the hotel for my own safety – advice I was happy to take.

Allow plenty of time travelling back to Baghdad airport

Getting back to the airport is another story of security.  I was picked up by my host and driven to a check point several miles from the centre of Baghdad and from the airport. At this point, I changed to a taxi having gone through another check point and personal search. Then the taxi is stopped for another check, get out of the car and the car is searched with sniffer dogs, the bonnet up, doors open, boot open and I go for a bag search and personal check (Passport and ticket).

SAFI am accused of being Sir Alex Ferguson although what Alex Ferguson would be doing in Iraq, I have no idea. This has happened to me before in Algeria – but really – do I look anything like SAF??

Final check is like airport entry security, but about a couple of miles from the airport.  Once negotiated, we resume the journey to the airport terminal. Ah! We are finally there.

Oh no you are not!  I am dropped in an empty road outside the terminal, and quite a way from it. There is an unnerving lack of people to see or talk to or ask directions from.  I was a little alarmed at this point since the taxi driver did not speak English and he waved me towards the terminal and drove off.  Was I being fed to the lions?  There was virtually no one around, and the terminal doors are all blocked up and blacked out.  At this point, as I walked towards the terminal to find a door that was open, I was approached by a security guard.   I assumed he was a security guard since he had a uniform and a high vis jacket, and a gun, obviously, they all do. I certainly treated him with the respect which a man with those accoutrements deserves – the gun mostly: hi-vis Jackets I have less respect for.  Rather surprisingly, I was asked to leave my bags in the middle of the road and leave them there (again a little unnerving).  But the situation improved when some other people turned up a few minutes later with bags and left them next to mine in the middle of the road.  You are asked to walk away a considerable number of meters while a sniffer dog checks to make sure there are no explosives in the bags. If all OK, (reassuringly, I had no explosives, or did my fellow travellers – I am not quite sure what happens if the you do!)  then you go on to the final security check to get into the airport terminal, and one more security check to actually get to the to check in desks.

bagdadairportAfter check in, and after passport control, there is one penultimate security check.  At this point, there was a man with a HUGE parcel wrapped up with string in that plastic laundry bag checked material (what is wrong with suitcases?) that was too big to go through the final scanner and had become lodged in it.  After some heated discussion (all Arabic seems to be heated to me!) the matter was resolved. No need to scan that big bundle of whatever it is, because he can take that on the plane!  I hope it wasn’t my flight he was on! And the final security check is just before boarding the plane, but different rules apply to this one.  Shoes must be taken off! (this is the first of, what, perhaps 8 screenings when my shoes were required to be removed). And they asked me if I had a lighter!  I don’t think it was to light their cigarettes. I showed them my Nicotine chewing gum and offered them some. They declined.  Not much demand for nicotine chewing gum – Smoking is allowed everywhere in Iraq. I get onto the plane (again via Istanbul to London) and reflect on a very interesting trip.

In summary – 5 tips for visiting Baghdad

My advice to my staff and to other business visitors is:

  • Iraq (well Baghdad) is very safe for international business visitors
  • Get the right introductions and a local host / representative
  • Travel light
  • Be prepared
  • Have your Alex Ferguson autograph ready (or whichever famous westerner you have a remote likeness too..)

Hope this rambling article was of use to you.  If anyone needs support with subsurface engineering then please give me a call!

ConvEx PTA software has powerful benefits

Posted by

ConvEx, the innovative pressure transient analysis software launched this Spring by OPC, has received very positive reviews from the global well testing community.   The consensus is that the ConvEx approach provides clear benefits across the entire well range and is particularly powerful when applied to unconventional wells.

In March, Piers Johnson presented to the annual SPE Well testing workshop in Dubai and in April, Riley Smith presented to at the AlMansoori Technology Day in Abu Dhabi.  Both presentations were very well received by the knowledgeable audiences.

Dubaievent

Piers said “I was delighted to have been invited to present at the workshop and to have the opportunity to share the benefits of ConvEx. I am particularly excited by this new solution as it can significantly increase the accuracy of the reservoir description, and therefore production forecasting in unconventional reservoirs and can deliver results far quicker than traditional models.”

Riley said “I presented a very brief overview of ConvEx at the AlMansoori Technology day and was pleased to see it generated a lot of interest, including from Mr. Yasser Saeed Al-Mazrouei, the CEO of ADMA/ZADCO. ”

Riley Smith AlMansoori

ConvEx has been developed by Michael Levitan, OPC lead PTA consultant, and was first presented to the Well Testing Network in Houston (involving well testing experts from leading companies including BP, Expro, ExxonMobil, Halliburton, Shell and Schlumberger).  The feedback was incredibly positive (see below)

“Whilst this technique appeared to provide clear benefits across the entire well range, its application to unconventional wells may prove particularly powerful.”

ConvexgroupConvEx (short for Convolution Explorer), significantly improves the accuracy of well surveillance analysis and forecasting production, particularly in unconventional reservoirs. ConvEx allows the user to derive a unit rate drawdown response function interactively with the well bottom hole pressure data and surface flow rate measurements which can then be used for future production forecasts.  This is particularly useful in unconventional reservoirs where there are no or few build ups just producing data.

Piersweb“We have received significant interest in ConvEx, particularly from clients with unconventional wells.  I would encourage anyone interested in the topic to contact me quickly as we are already scheduling projects to the end of 2017.”

OPC announces alliance with Fraser Well Management

Posted by

OPC has formed an alliance with Fraser Well Management which brings together the subsurface engineering expertise of OPC with the well engineering capabilities of Fraser Well Management in one co-ordinated service offering.

The alliance provides customers with an expert integrated “one stop shop” service incorporating all stages of the asset from geoscientific investigation, subsurface engineering through to well engineering and project execution.

When well planning, management and interpretation are performed by different parties in isolation they often result in poorly understood project objectives due to a lack of understanding of the subsurface drivers. The OPC/Fraser alliance ensures that these activities are planned and operated with execution and interpretation in mind and removes the communication barriers that often exist between the subsurface and well execution disciplines.

Piers JohnsonPiers Johnson, Managing Director of OPC commented “I am very excited by the alliance with Fraser Well Management. There is an excellent cultural fit between our businesses – both being established subject matter experts in our fields with long term customer relationships based on reliable and high-quality work. Together we can provide additional expert services to our customers and ensure that geoscientific investigation, well planning, testing and interpretation is performed efficiently, accurately and cost effectively.”

Nick FordNick Ford from Fraser Well Management said.” We have worked with OPC on several projects worldwide in the last couple of years, this alliance announcement cements that relationship. The key attraction for both organisations is the complementary relationship, where OPC can support our clients on the subsurface aspects and conversely we can support OPC on the well engineering aspects. We look forward to developing our relationship further over the coming years and delivering some outstanding results for our clients. “

This agreement with Fraser Well Management is the second strategic alliance announced by OPC in as many years. Early in 2015, OPC signed an MoU with Intecsea Worley Parsons to develop an integrated subsurface and subsea facilities management service. The alliance with Fraser Well Management will now augment this original agreement to provide a fully integrated reservoir to market (R2M) model.

Maximizing Hydrocarbon Recovery with Seismic Data

Treat Your Seismic Data with Respect and You’ll be Rewarded with Increased Production

by Brendan J Keating,  Geophysics Consultant advising OPC

During my thirty-one years working as a geophysicist in the Worldwide E&P Industry I’ve witnessed big changes in the methods of seismic interpretation. Gone are the days when we used paper copies of 2D seismic lines, coloured pencils and hand-drawn paper maps to find oil and gas. Modern seismic interpretations are performed using digital 3D seismic data loaded onto workstations. These changes have been brought about primarily by the fantastic improvements in computer hardware and software.

Seismic 3dToday geoscientists can map oil and gas fields with a level of precision and detail unimaginable in the days of paper seismic data. They can go further by using the digital depth maps as starting points for integration with geological and reservoir engineering data to create static and dynamic models of the fields. In addition modern computer workstations and software allow additional information on reservoir properties to be extracted from the seismic data, a process referred to as quantitative geophysical analysis. By building accurate reservoir models E&P companies can optimise the numbers and locations of planned production and injection wells and thereby maximise the hydrocarbon production from their fields.

Whilst it is true that large volumes of oil and gas were discovered using paper 2D seismic data during the 20th Century, the sparseness of the data often meant that it was difficult to optimize recovery from the fields. It is only through the use of 21st Century digital technology and 3D seismic data that we can really begin to maximise the recovery of hydrocarbons. These improvements have led to the rejuvenation of many mature fields around the World. A good example is the Forties Field in the UK North Sea, which was discovered by BP in 1970 (using paper 2D seismic data and coloured pencils) and brought onstream in 1975. By 2003 BP had recovered 2.4 billion barrels of oil from the field. The current Operator (Apache Corporation) is investing in modern evaluation techniques, including quantitative geophysical analysis, to increase the ultimate recovery of oil from the field. They expect to recover an additional 800 million barrels of oil. Similar success stories can be found elsewhere in the North Sea and US.

fortiesfield

However as a consultant I’m still surprised to discover that some clients do not follow the approach of companies like Apache and take full advantage of the modern seismic processing capabilities and the useful information which can be extracted from the data. By ignoring this information these companies often waste money drilling expensive wells in poorly chosen locations and hence fail to maximise hydrocarbon recovery efficiency. Yet a relatively small amount of money spent on analysing the seismic data would help to put the well in the optimum location.

A common problem is the drilling of wells into fault zones. Faults should generally be avoided by wells because they can remove reservoir rock and act as baffles to hydrocarbon flow. Even worse they can act as conduits for formation water to flow into the well. Quite often the field itself will be covered by high quality modern 3D seismic data. The data will have been processed to Pre-Stack Time Migration (and sometimes through to Pre-Stack Depth Migration.) The early appraisal and production wells will have been drilled on locations mapped using these data. However the errors in selecting optimum locations for new wells will often stem from the belief that the final processed 3D seismic data is somehow perfect.

In reality the 3D seismic data product is just an estimate of what the subsurface structure may look like based upon the best velocity models and the processing steps derived from the latest software. The key factor to remember here is that seismic data is acquired in time. We need velocity information to both process the data accurately and to convert it to depth. The velocity models used in the processing will have been best estimates only, usually derived iteratively during the processing itself. The chosen reservoir target location may have looked unfaulted on the seismic data prior to drilling. However if there are errors in the velocity models then the seismic reflectors will not have been moved (or migrated) to their correct positions during the Pre-Stack Time Migration processing. Hence the faults will not be in their true locations and there is a risk that a proposed new well will be drilled into one.

The amount of uncertainty in fault positions can be surprisingly large. I once worked on a development project, located onshore Gulf of Suez in Egypt, where the field was covered by high quality modern 3D seismic data which had been processed to Pre-Stack Time Migration. The main fault trend in the Gulf of Suez is NW-SE or “Clysmic.” When the 3D seismic data was reprocessed using Pre-Stack Depth Migration it was found that all the Clysmic faults migrated 125 metres to the SW! This helped to explain why some of the early appraisal wells had failed to find the reservoir sands!

Gulf of Suez

Quantitative geophysical analysis is a very important part of seismic data processing that has expanded enormously over the last fifteen years. It relies on the principle that different rocks have different physical properties and that these can affect both compressional (p-waves) and shear waves (s-waves) in different ways. In addition the presence of fluids within rocks (especially compressible fluids such as oil and gas) will change their densities and elastic properties and hence change the character of the seismic reflections. Under the right physical conditions these effects will be recorded during the acquisition of the seismic data.

In quantitative geophysical analysis we take the seismic data and work backwards (invert) to determine some of the physical properties of the rocks. One of the most important reservoir parameters to be derived is porosity. The great advantage of processing the seismic data in this way is that we can predict porosity in the areas between and away from the wells. This enables more accurate and detailed reservoir models to be generated which help to reduce risk of failure by highlighting optimum locations for production wells.

I used the phrase “right physical conditions.” Quantitative geophysical analysis is usually performed in Tertiary Basins, such as those offshore West Africa, where the geologically young rocks are relatively unconsolidated. These often have the right physical properties to enable the generation of seismic responses associated with the presence of hydrocarbons. UK-based geoscientists may be forgiven for believing that quantitative geophysics has limited use on geologically older and more consolidated rocks. They point out that bright seismic amplitude anomalies are rare in the gas-bearing Permian Rotliegendes reservoir sands of the UK Southern North Sea and where found are usually very weak.

However if the physical contrasts between the gas-bearing reservoir and the overlying rock layers are sufficiently large then seismic amplitude responses will be produced regardless of geological age. For example gas-bearing Carboniferous (Visean) sandstones in the Dnieper-Donets Basin of the Ukraine produce bright seismic amplitudes at depths of up to 3000 metres despite their great geological age. If there is well and velocity data available then the geophysicist can work with the petrophysicist to analyse the rock physics and make a prediction of the expected seismic response of the target zone. It is always worth considering performing quantitative geophysical analysis in areas of older geological rocks. Quantitative geophysical analysis should not be restricted to the Tertiary rocks.

OPC has the capability to perform a wide range of subsurface geophysical, geological, petrophysical and reservoir engineering studies. Seismic, well and reservoir engineering data are integrated to produce static and dynamic models of fields. The static models are used to provide accurate estimates of oil and gas volumes in the reservoirs. The dynamic models are used to optimise the locations of future production wells in order to maximise the recovery of reserves.

Brendan Keating

As part of the process OPC will analyse the quality of the data being input and make recommendations for improvements. The most common area for improvement is in the quality of the seismic data. This usually becomes obvious during the interpretation phase, especially when tying wells to the seismic data. The size of the misties will give a clue to the quality of the seismic data. In addition modelling of the rock physics will indicate whether the seismic data has potential for lending itself to quantitative geophysical analysis. If so then useful information on reservoir properties can then be extracted from the data.

The processing and interpretation of seismic data over a producing field is an ongoing process which needs to be continued whilst wells are being planned and drilled. The costs of 3D seismic reprocessing and quantitative geophysical analysis, is very low in comparison with the cost of drilling wells. Yet many companies still seem reluctant to invest in reprocessing, whilst wanting to drill more production wells. During this period of low oil prices it may be prudent to re-think this approach. Spending money on reprocessing in order to optimize the seismic data is likely to repay big dividends when planning and drilling future wells. It also helps to support the seismic acquisition and processing companies. If the seismic reprocessing saves the cost of just one dry well then it will have been money spent wisely!

ConvEx featured at AlMansoori Technology Day, Abu Dhabi

Posted by

ConvEx, the innovative forecasting solution for unconventional reservoirs, received significant interest from attendees at the AlMansoori Technology Day in Abu Dhabi on the 16th – 17th April 2017.

The Technology Day provided an opportunity for the AlMansoori Group, OPC’s partners in Abu Dhabi, to not only showcase their capabilities but also promote innovative and new technologies to the ADNOC Group.

The event, held over two days at the ADMA/ZADCO offices in Abu Dhabi was frequented by personnel from all areas of the ADNOC group and included a technical conference with presentations by AlMansoori and its partners.  The event was officially opened by Mr. Yasser Saeed Al-Mazrouei, CEO of ADMA/ZADCO who took the time to tour the exhibition to see for himself the technology on offer.

AlMansooriTechDay

OPC’s Middle East manager Riley Smith said “We were delighted to play a key part in this unique event.  It brought together innovation, technology and forward thinking and gave not only OPC but all who attended the opportunity to collaborate and share ideas on how we can work together with technology to successfully meet ADNOC’s targets in what remains a difficult time for the industry.”

In keeping with the theme of the event, OPC presented a new software application called ConvEx which significantly improves the accuracy of well surveillance analysis and forecasting production in unconventional reservoirs. ConvEx allows the user to derive a unit rate drawdown response function interactively with the well bottom hole pressure data and surface flow rate measurements which can then be used for future production forecasts.  This is particularly useful in unconventional reservoirs where there are no or few build ups just producing data. There will be an SPE paper released soon on ConvEx, should you require more information please contact Piers Johnson.

Riley added “I presented a very brief overview of ConvEx and was pleased to see it generated a lot of interest, including from Mr. Yasser Saeed Al-Mazrouei which was of great encouragement.”

The event also provided an opportunity for the many partners of AlMansoori to meet and learn more about each other’s services and possible opportunities to collaborate. Riley Smith commented “The range of oilfield services available amongst the group of companies is staggering, we have identified a number of projects across the region and we are certainly looking forward to providing our subsurface expertise to one or more of these exciting opportunities”

OPC presents at SPE Well testing workshop Dubai

Posted by

Piers Johnson from OPC played a key role at the 2017 SPE Well testing workshop in Dubai. The workshop, Well Testing – Technology, Operations, Sampling, and Reservoir Characterisation in the Current Price Environment, is the leading event for well testing in the SPE annual calendar.   Piers presented on two distinct topics:

  • Unusual Derivative Responses from Layered and Water Edge Drive Reservoirs
  • A Common Framework for Analysis of Well Test and Surveillance Pressure and Rate Data

The second presentation was based on the work of Mike Levitan, OPC Consultant, and explains how deconvolution can be applied to unconventional reservoirs as well as conventional reservoirs.  In unconventional reservoirs the reservoir volume investigated by a typical well test is confined to immediate vicinity of the well (as little as a few feet).  For this reason traditional well testing does not allow reliable assessment of the well long-term production capacity and is not a practical and proper approach for unconventional reservoir/well evaluation.   Mike’s framework involves an analysis technique based on pressure-rate deconvolution that is applicable for both well test and surveillance data.  This approach does not rely on any automatic pressure-rate deconvolution algorithms which are often too restrictive and not robust enough for surveillance data acquired in the course of routine production operations.

Piers said “I was delighted to have been invited to present at the workshop and to have the opportunity to share Mike Levitan’s new framework.  I am particularly excited by this new framework as it can significantly increase the accuracy of the reservoir description, and therefore production forecasting in unconventional reservoirs and can deliver results far quicker than traditional models.”

Piersweb“Attendees at the workshop were very interested in the new framework.  Mike will be publishing a full technical paper in the next few months but I would encourage anyone interested in the topic to contact me quickly as we are already scheduling projects into the summer of 2017.”

OPC attends EGYPS 2017

Posted by

Riley Smith from OPC attended EGYPS, the Egypt Petroleum Show which took place in Cairo on the 14-16 February 2017.  The event was the largest oil & gas industry gathering North Africa has ever seen and was an excellent forum for discussing opportunities in the Egyptian market.

EGYPS was a very timely event for OPC following our registration as an approved vendor with the Egyptian Ministry of Oil & Gas in November 2016.  This not only allows OPC to work more efficiently in Egypt but also provides our clients with cost recovery capability, in a market which is flourishing following several large gas discoveries including the super-giant Zohr gas field by ENI in August 2015..

As part of the registration process, OPC has formed a partnership with Elba Group, a local services company providing us with access to local support, infrastructure, environmental and logistics services in order to provide a more comprehensive service to OPC clients in Egypt.

RileylogoRiley Smith, OPC Manager – MENA, said “EGYPS was an excellent event which gave me the chance to meet with many companies interested in Egypt’s potential.  Having already met a number of senior government officials, it was great to meet with a number of operating companies looking at the opportunities available.”

Riley added “Our registration gives us access to the Egyptian Information Centre enabling us to provide comprehensive, expert and speedy services to companies seeking to enter the market. I would encourage any operators attending EGYPS who are perhaps seeking to evaluate opportunities in Egypt to get in touch with us as we can without doubt provide an unrivalled level of support on assessing these blocks”

New contracts update

Posted by

While the overall effect of the low oil price has been to dampen activity, OPC has been winning a large number of new contracts thanks to focusing on clear benefits to customers:

  • Expert knowledge of subsurface engineering
  • Flexibility to deliver projects, contract personnel and/or training
  • Cost effective rates given current market conditions
  • Integrated well services and field development partnerships

Middle East manager, Riley Smith said “Given the current market conditions, operators are looking for partners that can provide flexible, low risk and cost effective services.  This is excellent news for OPC as our model of a core engineering team supported by specialist consultants is particularly competitive at present.  We are able to deliver projects at day rates that are approximately 30% lower than three years ago due to the current market conditions and flexibility of our consultants.”

Shown below is a selection of new business wins over the last quarter:
