Vertical and lateral depositional and structural heterogeneities are key elements influencing pore networks and flow properties in carbonate reservoirs. A detailed understanding of property heterogeneities in reservoirs on an inter-well scale is a prerequisite for economically increasing hydrocarbon recovery using enhanced recovery methods. With limited resolution in the subsurface this calls for constraining heterogeneities in outcrops which are analogous in depositional and structural settings compared to the reservoirs. Our understanding must be improved on depositional environments, lateral and vertical facies changes as a function of relative sea-level changes, environmental factors (wind energy, ocean currents, climate, etc). Furthermore, with an ever decreasing well spacing in existing reservoirs the occurrence, distribution and impact of fracture systems on subsurface flow must be better constrained and understood.
Our group has embarked on creating high resolution static and dynamic reservoir models with the aim to investigate the impact of heterogeneities on recovery under different production configurations and recovery mechanisms. For this we are utilizing first class outcrops of Jurassic and Cretaceous carbonates in central Saudi Arabia and Oman analogous to the super-giant reservoirs of the region. Comprehensive 3D data sets are being collected on a similar scale as small sector models of hydrocarbon reservoirs under development.
The aim of this project is to improve the understanding of reservoir heterogeneity by
Who are we looking for?
To supplement our existing team of stratigraphers, geophysicist, and reservoir engineers we are looking for a post-Doc researcher with a structural geology background and focus on faults and fractures in sedimentary sequences.
Applications are sought for a two-year postdoc position. The position will include a competitive salary based on the candidate’s qualifications; benefits include medical and dental insurance, free furnished housing on the KAUST campus, annual travel allowance to visit home country, annual paid vacation, and other generous benefits.
The successful applicant will be a member of the Carbonate Reservoirs Geology group (CaRess Geology) led by Professor Volker Vahrenkamp, affiliated to the Ali I. Al-Naimi Petroleum Engineering Research Center (ANPERC) at KAUST.Läs mer
