OPCs distinctive capability in integrated reservoir modelling is the ability to integrate across as many disciplines as appropriate
It is still often true that reservoir studies are treated as linear exercises. Geophysical interpretation, petrophysical analysis, geological interpretation and modelling, dynamic modelling, production technology and facilities design are carried out sequentially. OPC believes that this approach is fundamentally flawed because it fails to account fully for interactions between the work of the different disciplines. For example:
- The results of well test analyses can inform the geophysical and geological interpretations.
- MDT interpretations can influence both geological and geophysical understanding.
- Understanding of facilities design and cost can affect the appropriate reservoir engineering studies e.g. whether the higher cost of horizontal wells will be justified by reducing the required capacity of water handling facilities.
In carrying out integrated reservoir studies, we engage with all disciplines throughout the study. This delivers both better results and more cost-effective projects.
For example, if we recognise early on that historical production data is the most reliable guide to future field performance, we can minimise the money and effort spent on petrophysics. This means that integrated reservoir modelling studies carried out by OPC are typically both more competently executed and lower cost than those carried out by our competitors.
