Abstract

Electric Submersible Pump (ESP) merupakan jenis dari Centrifugal Pump untuk mengangkat fluida darireservoir ke permukaan pada laju produksi tertentu, maka kemampuan suatu pompa untuk mengangkatsuatu level fluida tertentu hingga kepermukaan seharusnya disesuaikan dengan kapasitas sumur itusendiri. Sumur X110 berada di lapangan Bentayan dimana reservoir sumur ini memiliki tenaga pendorongair (water drive). Sumur X110 dari perhitungan kurva IPR Vogel memiliki produksi optimum 1227,853BFPD menggunakan pompa ESP TD 850 140 Stages 60 Hz dengan ukuran motor30 HP 425 V 44,5 A.Dari test produksi aktual 4 April 2014 diketahui produksi sebesar 460 BFPD sehingga produksi masihdapat dioptimasi dengan mengevaluasi pompa ESP terpasang. Dari hasil evaluasi didapatkan tipe pompauntuk mendapatkan produski optimum sumur X110 adalah dari EJP dengan tipe IND 1300 147 stages 60Hz dengan ukuran pompa 50 Hp, 815 V, 39 A.

Abstract

PT BaturonaAdimulya is a coal mining company located in BabatSupatSubdistrict, MusiBanyuasin Regency, South Sumatera Province. Based on the calculation of overburden digging volume at Pit 2 with progress survey that is measurement using total station sokkia set 3010 instrument and the processing and calculation using surpac 6.5.1 result in overburden volume or cover ground 251,941 BCM. Coal mining in open pit will cause environmental changes, either small hills or mined holes (voids). The burden removing from Pit 2 by backfilling method in the mining area will minimize the voids that occur. PT BaturonaAdimulya has void in Pit 1 as large as 4.8 Ha, and will do backfilling that requires overburden material as much as 295.721 BCM / Ha and top soil as much as 33,600 LCM / Ha. The voids left at the end of the mine without any utilization planning have the potential to cause undesirable impacts on the environment. Therefore, PT BaturonaAdimulya is planning to revegetate the void area so it can be utilized and become a green field again as before
