Production test is one of very crucial activities in the geothermal field development process. The condition of the well, reservoir characteristics, and production capacity of the well can be determined by production test. This study describes the production analysis results based on case studies of XYZ-well production test at Lahendong geothermal field in Indonesia using Separator Method. Th…
In general, the geothermal reservoir in Indonesia is water dominated that produce steam and brine. The brine that produce is contained by silica, so that the brine needs a cooling process executed in pond. This process aims to precipitate silica contained in the brine, so that the occurrence of silica scaling in the pumping process towards the injection well could be avoided, yet based this stu…

Silika yang terlarut pada brine hasil pemisahan separator diendapkan pada pond-pond sehingga saat proses pemompaan tidak terjadi pengendapan silika amorf didalam pipa, namun hasil analisa menunjukkan bahwa masih adanya silika yang terbawa dan terendapkan dalam pipa saat proses pemompaan. Hasil analisa menunjukkan 33 ppm silika terendapkan disepanjang pipa alir brine, selain itu hasil analisa ju…
Tekanan kepala sumur merupakan aspek penting dalam proses produksi panas bumi, tekanan kepala sumur berperan sebagai pengontrol besar kecilnya laju produksi yang didasarkan atas beberapa aspek seperti Silica Saturation Index (SSC) dan kecepatan aliran fluida. Nilai dari tekanan kepala sumur berbanding berbalik dengan fluida yang diproduksikan, dimana semakin besar tekanan kepala sumur maka sem…
