Abstract

Sumur R-1 merupakan sumur eksplorasi dimana akan diterapkan operasi perforasi, uji kandungan lapisan (UKL), danhydraulic fracturing dengan selalu mengganti rangkaian pada tiap tahapan operasi. Namun, pergantian alat tersebut menyebabkan operasi yang dijalankan menjadi tidak efisien dan dapat menyebabkan timbulnya permasalahan. Maka dilakukan rekayasan rangkaian sehingga ketiga operasi tersebut dapat dilaksanakan secara langsung dengan hanya menggunakan satu rangkaian. Hasil analisis dan perhitungan menunjukkan aliran fluida yang turbulen dengan Reynold Number (Nre) lebih dari 4000 dengan total pressure loss pada DST akibat friksi adalah sebesar 123046.724 kPa. Analisis dilakukan pada tiga titik rangkaian drill stem test (DST), yaitu saat pengecilan diameter pipa, fluida keluar melalui port rangkaian, dan pada saat fluida keluar menabrak casing. Hasil perhitungan pada pengecilan diameter pipa (0-30°) pipa tidak akan wash out hingga menit ke-47678411 dan pada output port (45°) akan wash out pada menit ke-188. Injeksi mainfrac juga dapat dilakukan selama 33 menit dengan friction angle maksimal pada 47.3° dan shearing rate sebesar 2.38 mm/min.Rekayasa pada rangkaian peralatan UKL sebagai alternatif dan solusi berhasil mencapai target NPT (<5%) serta tercapainya efisiensi hari kerja sebanyak empat hari.

Abstract

The production wells in the South-East Sumatra (SES) Block are characterized as a mature field with a high water cut, requiring significant energy to lift fluids to the surface. The main challenge faced is the high energy inefficiency of the Electrical Submersible Pump (ESP). Therefore, this study aims to evaluate ESP performance based on energy loss analysis, determine the best optimization scenario to reduce energy requirements, and analyze potential operational cost savings. The research method involves evaluating the distribution of energy losses in hydraulic components (friction, backpressure, and pumps) and electrical components (motor, cables, and surface equipment). Based on this evaluation, three optimization scenarios were conducted: backpressure loss, frictional loss, and pump loss. Furthermore, a cost savings analysis is carried out by comparing the costs before and after optimization. The results indicate that energy inefficiency in high flow rates wells is dominated by backpressure and friction, while in relatively small flow rates wells is caused by low pump efficiency and backpressure. The application of the best optimization scenario in the five wells can reduce the total energy requirement from 768.83 kW to 568.21 kW. This resulted in a cost reduction from US$512,641 to US$378,869.
