Expert geosciences consultancy, studies and projects


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.

Julie BuckinghamJulie Buckingham is the Principal Geoscientist at OPC has more than 20 years oil industry experience, gained mainly with operators in the UKCS, working on all clastic reservoirs of the Central, Southern and Northern North Sea, and West of Shetlands. She also has experience of carbonate plays onshore UK, Italy and Middle East.


BRENDAN_KEATINGBrendan Keating is our expert interpretation Geophysicist who has worked on assets in over 60 countries for a range of companies from start-ups to majors (including ARCO and Conoco) and spent five years in investment banking at Jefferies Randall & Dewey in London.


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

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...
