Abstract

Kebocoran pipa produksi (production tubing) dalam kegiatan eksplorasi minyak bumi dan gas alam dapat mengganggu proses produksi. Untuk itu, diperlukan metode yang tepat untuk memperbaiki kebocoran tubing tanpa menghentikan proses (shutdown). Salah satu metode perbaikan yang dapat digunakan adalah in situ well repair. In situ well repair dilakukan dengan penambalan (patching) menggunakan polimer superabsorbent jenis polyacrylamide pada flow rate dan tekanan tertentu. Pada penelitian ini dilakukan simulasi dengan CFD dan FEM untuk menganalisis pengaruh tekanan dan flow rate yang menghasilkan kemampuan in situ well repair paling optimum untuk mengatasi kebocoran tubing dengan menggunakan software ANSYS. Hasil yang diperoleh yaitu semakin besar flow rate dan tekanan, maka akan semakin besar pula kemungkinan terjadinya deformasi patch pada lokasi in situ well repair. Flow rate yang menghasilkan kemampuan in situ well repair paling optimum adalah 1000 bpd dengan nilai tekanan sebesar 36,82 Pa pada lokasi patch dengan jarak 180 inch dari dasar tubing. ======================================================================================================= Leakage of production tubing in crude oil and natural gas exploration activities may disrupt production processes. Therefore, a proper method is needed to repair the tubing leakage without shut the process down. One of improvement method that can be used is in situ well repair. In situ well repair is done by patching using superabsorbent polymer, in this case is polyacrylamide, at certain flow rate and pressure. In this research, simulation using CFD and FEM is us ed to analyse the effect of flow rate and pressure that give the most optimum in situ well repair capability to overcome tubing leakage using ANSYS software. The results obtained are the greater flow rate and pressure, the greater possibility of patch defo rmation at the location of in situ well repair. Flow rate that produces the most optimum in situ well repair capability is 1000 bpd with a pressure value of 36,82 Pa at the patch site with a distance of 180 inches from the bottom of the tubing
