The main objective of a development team is to identify the type and scale of heterogeneity that is most likely to affect the distribution of non-recovered mobile oil and gas in their subsurface reservoirs. The clastic depositional environment is particularly complex and many factors may cause a lower than expected recovery. Outcrops, cores, borehole images, logs, production test and reservoir level seismic can help provide detailed information about the architecture, fluid flow behaviour and the heterogeneities in a reservoir.
Course Level: Skill Duration: 5 days Instructor: Evert Uitentuis
Designed for you, if you are...
A geophysicist, geologist, petrophysicist or reservoir engineer involved in exploration, appraisal and development of clastic oil and gas accumulations
Participants should have a basic knowledge of clastic reservoir geology.
How we build your confidence
This course is designed to provide the best possible interaction between lectures and multidisciplinary team related exercises. The focus of the course is on understanding the needs of the different parties involved in reservoir performance prediction. It will be shown how the integration of geophysical, petrophysical and reservoir engineering data is the key to designing realistic static and dynamic reservoir models.
