Expert geosciences consultancy, studies and projects

Geosciences

OPC has the capability to perform a wide range of subsurface geophysical, petrophysical and geological studies as well as seismic interpretation projects.

OPCs in-house geoscience and engineering team work closely together using industry standard software such as Petrel, integrating geophysical, geological, petrophysical and engineering data to characterise a static reservoir model that is geologically reasonable for any given basin or petroleum province.

OPC has supported clients in license rounds and our team can quickly evaluate available blocks, map prospects and leads, assess the risk and uncertainty associated with each element of the petroleum system, and provide work programme support moving forward.

Regional geological and integrated basin studies can be performed in locations around the world, from frontier to mature basins.  OPC can offer farm out services to clients, including evaluating data, constructing and hosting data rooms. Furthermore, we can provide technical support at all stages of the farm out process.  Seismic interpretation projects can be carried out at a basin and field scale.

OPC provide a range of petrophysical interpretation services, from quick single well evaluations, to large scale multi-well studies, including the integration of log, core and geological data, and input into geological modelling.

OPC has access to a full range of industry standard software technology including Petrel, IHS Kingdom and Recall.

OPC has the resources to provide QA/QC services in support of onshore or offshore seismic acquisition projects.

Some recent geosciences projects and studies

Geothermal Modelling – Doublet System
OPC performed modelling of a geothermal open-loop doublet system (injector and producer). The objective was to perform NODAL analysis using a range of sensitivities to develop scenarios and outline recommendations...
Prospect Screening
OPC’s independent assessment of the commerciality and chance of success of the prospect helped the client to decide on whether the prospect is a farm-in opportunity they should pursue. OPC’s...
Extensive reservoir study
OPC conducted an extensive reservoir study of a large field in West Africa in order to define and assess the remaining production opportunities in the field.
OPC was retained by a leading international bank to provide technical expertise into the annual re-determination of loan facilities for the bank’s clients who have multiple assets across Egypt and...
Independent Engineers’ Report
A multi-disciplinary team at OPC London office conducted a fast tracked independent review of a new discovery in UKCS to support the asset owner to generate investment interest. 
Positive feedback for Middle East training
We have received some excellent feedback on the most recent subsurface training project, Sedimentology and Sequence Stratigraphic Analysis, delivered to a client in the Middle East.
Producing oilfields re-development study
OPC deployed a multidisciplinary team of 11 people (with subsurface, facilities, drilling and economics expertise) to undertake an extensive 5-month re-development study for a group of oilfields in the Middle...
Reserves and production forecast audit
OPC performed a reserves review and production forecast audit for a Global Bank based in the Middle East for two separate oil and gas companies with assets in Egypt and Oman. 
CPR and technical due diligence reports
OPC reviewed the resources in two blocks in Africa and provided a Competent Persons Report (CPR) letter summarising the findings of its Due Diligence Reports and Reserves Audit. 
Technical due diligence & economic modelling
OPC was retained by an International Bank to perform a technical and operational audit of Middle East operator and develop an economic model based on the Petroleum Agreement that could...
Integrated reservoir modelling and simulation
OPC generated a static model (including full seismic interpretation and geological modelling) for a field in Kazakhstan. We then performed a history match and a production forecast for the producing...
Static modelling and waterflood simulation
OPC generated static and dynamic models, that were optimised for waterflood simulation. A history match of the model was performed, and several injection scenarios were reviewed. The most suitable scenario...
Competent Persons Report
OPC generated a Competent Persons Report (CPR) for a block, onshore South America. The report formed part of documentation published to the stock market and assisted the asset owner to...
Technical due diligence & asset evaluation
OPC provided technical due diligence and evaluation of a potential asset purchase in the UKCS, including a review of a reservoir model, production data and development scenarios
Surface and Subsurface evaluation
OPC performed a subsurface and surface evaluation of a field in West Africa, including validation of the static and dynamic model and recommendations with respect to the client’s business objectives.
Reserves and Development Plan Review
OPC performed a review of the reserves and development plan for a Gas Field, offshore Africa. The workscope included a reviewing of multiple static and dynamic models, petroleum economics and...
Petrophysical Interpretation for North Africa
OPC performed a petrophysical interpretation of a well in North Africa, with a complex multi-mineral lithology. The work was carried out with a view to re-considering the conclusion reached by...
Modelling and simulation review
OPC has successfully completed a full static and dynamic modelling and simulation review in order to assess the feasibility of the operator’s appraisal and development plan.  
Integrated consultancy team onsite at NOC
Between 2006 and 2013, OPC had an exclusive contract with an NOC as the Petroleum Engineering Consultancy (Contract Engineering and Geosciences) responsible for providing technical expertise in the areas of...
