The company has completed a comprehensive reservoir modeling and development planning study for Pricaspian Petroleum Company in the southwestern part of the Pre-Caspian Basin. The field has been under development for more than 25 years and is characterized by complex geological conditions, including multiple faults, stratigraphic unconformities, high oil viscosity, and significant reserve depletion.
Our team developed a high-resolution geological and hydrodynamic model using specialized software solutions. An analysis of several development scenarios was conducted, leading to the identification of a strategy with the potential to increase oil production, despite the current recovery exceeding 90%, through detailed mapping of remaining oil reserves and precise placement of new drilling locations.
Key Achievements
- Refinement of the field’s geological structure through detailed stratigraphic correlation, considering the pinch-out of Jurassic deposits into the base of the Cretaceous.
- Preparation of a reserves report for oil and dissolved gas.
- Comprehensive history-matching and dynamic model calibration, which revealed the presence of significant remaining movable heavy oil reserves, most of which are currently uneconomic to produce.
- Evaluation of multiple development scenarios, where the optimal case demonstrated the potential to increase oil production by up to 20% through optimal placement of new wells, taking into account the current high reservoir depletion of over 90%.
Feedback
This field represented one of the most challenging geological cases, given the stratigraphic unconformities, numerous faults, and the current high level of reserve depletion. Thanks to the detailed and methodical approach of the Global Geo Consulting team, our company now has a clear understanding of the field’s remaining potential and future investment opportunities..
