2023-05-29T11:40:15+07:00

The reservoir pressure in the P-N oil well is currently showing a significant decline. Some oil wells cannot flow naturally, so artificial lift is required to maintain Jabung oil production and deplete the remaining oil reserves. Analysis and evaluation of the use of artificial lift electrical submersible pump (ESP) in the P-N62 well using calculation and simulation to see the production performance of a well after adding artificial lift based on the results of the calculation it is determined that the ESP TD800 Series-400 with 117 stages with the ability to produce up to 990.96 BFPD and has an efficiency of 58.67% which will be used to increase the production rate at the P-N62 well.

The wells in Field J, using Electrical Submersible Pumps (ESP), have replaced their natural flow operations. To optimize this ESP well and pipeline network, the research focuses on adjusting the ESP pump frequency within the Pipesim simulator, increasing it to enhance oil flow rates. This study employs a quantitative approach, where field data is analyzed and input into a simulation model that replicates real-world conditions. The analysis encompasses changes in flow rates and pressures, comparing the base case to post-optimization simulations. The results indicate a substantial increase in the initial oil flow rate from 578 STB to 720 STB/d, with an increase of 142 STB/d, when the pump frequency is raised to 60 Hz. This frequency adjustment significantly boosts pump discharge pressure, providing the added energy needed to transport fluid to the surface.

Penentuan Nilai Porositas pada Sample Berea di Routine Core Analysis Laboratorium BBPMGB “LEMIGAS”

2023-12-26T23:19:37+07:00

This study aims to analyze routine cores, especially for determining the porosity of a rock. The samples tested by the coreval tool were 3 samples of 1.5 inch diameter with a length of 4.5 cm each. The sample used is a sample of Berea sandstone. When the core sample comes, it is continued with ct-scan and spectral gamma ray. The next process is washing the fluid in the core sample. After cleaning from other fluids, the core sample will be dried in the oven. After it is completely dry, the sample must be stored in a desiccator containing silica gel. After ambient temperature, then the core sample is tested using Coreval 700. The data inputted into the coreval computer are the name of the core sample, the dry weight of the core, the length of the core, and the diameter of the core. The coreval tool takes readings of bulk volume, pore volume, and porosity. This reading resulted in bulk volume values of 50.091 cc; 53.446 cc; and 52.410 cc, respectively. The pore volume value of each sample is 12.091 cc; 13.787 cc; and 13.385 cc. As for porosity, the value of each sample is 25.767%; 25.795%; and 25.540%.

ANALISIS PERBANDINGAN PRODUKSI SEBELUM DAN SETELAH WELLSERVICE PADA SUMUR X LAPANGAN Y PT PERTAMINA EP

2023-10-25T13:42:26+07:00

Well X started production on February 9^th, 2012 with oil production of 217 BOPD and peak production on March 1^th, 2012 with oil production of 2756 BOPD. As production progresses, the reservoir pressure will decrease resulting in a decrease in the production rate. Well X was shut-in on March 7^th, 2023 with oil production of 197 BOPD and watercut reaching 91.27%. The location of this study is administratively located in Campurejo Village, Bojonegoro District, Bojonegoro Regency. Analysis of well potential and well forecasting are carried out by the Wiggins method. This method was chosen because the X well has a three-phase fluid and a high water cut. The calculation results show a maximum flow rate of 4111.52 BFPD and an optimum flow rate of 2466.91 BFPD. After calculating the optimum flow rate, and to avoid water cloning, it is recommended that wells be produced with a production flow rate of 2412.54 BFPD at a well base flow pressure (Pwf) of 1368 Psi.
