| Summary: | Three of the Delta Mahakam Block's offshore gas fields are already at decline phase. LLP (low-low pressure) compressor project that has the objective of decreasing well operating pressure is proposed to maintain gas production levels. The project will be completed in three phases, beginning with the pilot project. The pilot project was completed in 2021, but the liquid rate was higher than expected. Higher liquid rates have delayed project completion and increased the cost of additional equipment. Root cause analysis with the Kepner-Tregoe method concludes that a higher liquid rate is due to inaccurate measurement. A new plan for the next phase must be decided in order to accommodate the most recent evaluation, which is based on the pilot project results.
The research is focused on defining the best course of action that will be implemented for the third phase of the LLP project. The third phase, which is planned for eight offshore platforms, is the primary focus of this research. Recent evaluation of the third phase indicates cost increases, revenue reductions, and project execution delays. A Simple Multi Attribute Rating Technique (SMART) approach is used to evaluate four alternatives for the third phase, namely: (1) cancel the LLP compressor installation on eight offshore platforms; (2) install the compressor on eight offshore platforms in the same time frame; (3) install the LLP compressor only on selected offshore platforms; and (4) install the LLP compressor on eight offshore platforms in sequence. Five attributes for alternative evaluation are profit, cost, production, and compliance with regulations. Attributes are defined with value-focused thinking and refer to key performance indicators (KPIs) for companies. Based on the SMART result, it is concluded that LLP compressor installation on four selected offshore platforms is the best choice.
