Reservoir Engineering

OPC is one of the leading independent reservoir engineering consultants in the world providing services on a global basis to IOCs, NOCs and independent oil & gas businesses. Reservoir engineering studies have included phase behaviour and equation of state modelling and production engineering.

OPC has access to industry standard software technology including Eclipse 100/300, Petrel, MBAL, Prosper, GAP, Kraken and PIE.

Our highly skilled in-house team deliver a range of Reservoir Engineering projects that include;

Some recent reservoir engineering projects and studies

Static/Dynamic Model Rebuild
OPC completed an integrated geological modelling project for a client, which involved an entire static/dynamic re-build including a QA/QC of core, updated petrophysics and interpretation, a SCAL review, re-modelling the...
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. 
PTA and PVT review to determine gas caps
OPC undertook a review of existing PTA (Pressure Transient Analysis) data and existing laboratory PVT analyses from several wells in an offshore field in West Africa.
Oilfield simulation study
A simulation study was carried out by OPC to maximise the value of a large producing oil field in Central Africa. 
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.
PTA utilising deconvolution and ConvEx
OPC undertook a Pressure Transient Analysis (PTA) study utilising deconvolution and ConvEx. The PTA connected volumes calculated were comparable with those from modelling and ConvEx was successfully used to help...
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...
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...
