ABSTRACT
Base management provides framework for managing the production base and maximizing recovery through efficient depletion. A vital element of base management practice is system optimization which includes modelling, prioritizing, and implementing strategies to enhance production & reserves of all fields. The process starts with a holistic network model1 that includes integrating reservoir, wellbore hydraulics, gathering system and production facilities. System wide evaluation is conducted using this integrated model and recommendations are networked with cross-functional teams. Finally, these observations are ranked and executed as per business requirements. Given the vast number of active/shut-in wells & fundamentally different field types operated by UEP, this approach is pivotal to effectively manage base production.
This study focuses on key achievements in past few years which delivered fruitful results in terms of production and reserves addition. Below is the summary of activities:
Area-1 comprises of aging fields and the focus has been on creating network flexibility, re-accessing bypassed zones, and compressors modifications to bring the system in the most optimized operating window.
Area-2 is primarily gas producing region and opportunities on Well hydraulics, surface compression, system de-bottlenecking, and plant optimization remain in the forefront. Figure-3 demonstrates a case of successfully managed base through multiple optimization activities.
The initiatives discussed in this study significantly contributed to optimizing base production of Area-1 & 2, enabling them to maintain optimum production levels.
