Abstract

The basalt of "Ohi" Mount and the Andesite Hornblend on "Ser" Mount are a barrier to the flow of groundwater from "Ifa" Mount. Both are an influence on the productivity aquifer. The characteristic of lithology in water is an influence of the permeability coefficient. Falling head is one of the methods of measuring the determination of coefficient permeability. Based on the location measurement, To know the units of rock formed, (2) To know the Productivity aquifer system (local, medium and small); (3) To know the coefficient permeability of characteristics of lithology. Coefficient of Permeability A stream is said to be good if the nature of the rock type has a positive result or the greater the water pass rate, and conversely, the passing value of a negative result has a very small water pass rate. Its goal was to determine the relationship between lithology characteristics and permeability coefficients in the "BRG" area and surroundings. The "BRG" area and its surroundings, based on the location point of measurement of the rock unit, were the Breccia Andesite Hornblend unit, The Medium Productivity Aquifer Dominated. The average coefficient of permeability (K) is 63,300 cm/day. The five location measurements were: 1 st area DS, S1, 2 nd DS area, S2, 3 rd DN area, 4 th DD area, and 5 th DR. The aquifer of the five locations had through fracture permeability and had a type of steep hill morphology

Abstract

This research is a study of surfactant injection to increase oil production in layer AB-2B Meruap field managed by BWP MERUAP. Meruap field has decreased oil production. To increase production, one way to do this is by doing Enhanced Oil Recovery (EOR) so that oil production in the AB-2B layer increases. EOR is an advanced drainage from the reservoir. Surfactants and KCl as injection fluid in this layer are selected based on the results of laboratory data that have been carried out on the AB2B layer Meruap field. surfactant injection is used to reduce the fluid oil interface tension, where oil is trapped by capillary pressure and cannot move, so that the trapped oil can be removed by injecting the surfactant. Mixing surfactant with oil to form an emulsion that will reduce capillary pressure. The results obtained in the AB-2B Meruap field after surfactant injection was carried out was increased oil production

Abstract

Pada sumur “L-18” tekanan reservoir mengalami penurunan yang mengakibatkan laju produksi juga menurun, oleh karena itu dibutuhkan bantuan artificial lift jenis Electrical Submersible Pump (ESP) untuk mengoptimalkan laju alir produksi. Metode penelitian yang digunakan dalam tugas akhir ini yaitu dengan melakukan perencanaan desain. Hasil  perencanaan  desain   pompa    didapatkan pilihan  pompa  jenis  REDA  GN3200-60Hz  dengan  jumlah  stage  yang terpasang  sebesar 162.34 stage BHP motor sebesar 227.3 HP serta efisiensi pompa sebesar 62%, lalu  dipilih  jenis  motor  456  series  motor  dengan spesifikasi 60 iHz, 240 HP, 1993 V dan 78.6 A.
