Integrative optimization of shale gas gathering: Pressure-driven compression management and well development planning

Shale gas is a key unconventional energy resource known for its environmental benefits and efficiency. While existing research often narrows its focus to optimizing individual skid-mounted equipment (SME), it also overlooks the broader scope of long-term well development planning (WDP). Here, we address this gap by proposing a two-stage model for the integrated optimization of WDP and SME within shale gas gathering systems (SGGS). This model aims to enhance production efficiency and economic performance over time. The first stage optimizes WDP by examining the deployment strategies for separation metering skid (SMD) and dehydration skid (DSD), demonstrating a 3.92% reduction in the total cost of unpressurized equipment (UPE). The second stage integrates WDP with pipeline network pressure changes, optimizing compressor skid (CSD) deployment for rational pressure distribution. Application of this model to a shale gas field in China reveals its potential for achieving a more flexible and cost-effective SGGS. This research advances our understanding of SGGS optimization by addressing both equipment and long-term planning aspects, providing a comprehensive approach for improved field development.
