Specialist technical areas

Our Specialist Disciplines

OPC is recognised as one of the world’s leading subsurface engineering consultancies.  We our specialist in a range of technical disciplines including geosciences, production engineering, well test interpretation, reservoir engineering, pressure transient analysis and reservoir modelling.  

Commercial Services

OPC have experience in providing specialist consultancy, either through outsourced projects or by way of embedding experts within client’s organizations, to deliver commercial, operational and corporate support.

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.

Petroleum Economics

OPC provides a petroleum economics and commercial consultancy alongside our technical services and on a stand-alone basis.   This enables us to report and advise clients both economically and financially on OPC generated technical studies and intra company decision processes.


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

Pressure Transient Analysis

OPC specialises in Pressure Transient Analysis (PTA), also known as Well test analysis, which involves the interpretation and analysis of Drill Stem Test (DST), Extended Well Test (EWT) and Production/Injection permanent downhole gauge data. With a combination of operational and analysis expertise in well testing, OPC is able to maximise the information gained from your data set to give you a better understanding of your asset and enable you to make better business decisions.

Production Engineering

OPC’s production engineering / petroleum engineering expertise covers projects worldwide as well as various types of wells and reservoirs: oil, gas and gas condensate reservoirs; vertical, horizontal, deviated offshore and onshore producers and injectors.

Reservoir Simulation

Reservoir simulation is at the core of OPCs technical services department. We apply the latest technology and industry standard software together with highly competent in house engineering and geoscience staff, to build geostatistical models and up-scale them to dynamic models for black oil and compositional studies, highly fractured and faulted reservoirs studies, and the pilot studies and implementation of various EOR techniques.

Reservoir Surveillance

OPC provides specialist Reservoir Surveillance and monitoring services using Pressure Transient Analysis to help operators maximise revenue from their oil and gas assets. Effective Reservoir surveillance/monitoring can help:

Well Testing

Well testing is commonly the last task to be planned in an exploration project. Often this leads to the design and execution being carried out in a rush by personnel for whom testing is not their main focus and awareness of all stakeholder needs may be limited.

This can result in objectives not being clearly defined, money not spent wisely and potential loss of very significant data needed to evaluate development cases.

Drilling & Well Engineering

OPC’s drilling and well services capability covers a wide range of services on a global scale across a wide spectrum of different formations and subsurface conditions (HP/HT, H2S, Horizontal and Directional).

CCS Services

OPC offers subsurface studies for CO2 injectability and CCS development planning. We leverage our network of specialists for tailored solutions.

Digital Oilfield Consultancy

OPC provides Digital Oilfield Transformation consultancy and training to companies in the oil and gas sector. Specific services include Digital transformation strategy, digital maturity studies and training.
