Reservoir simulation is a process of mathematically modeling reservoir conditions by integrating various existing data (geology, geophysics, petrophysics, reservoirs, etc) to obtain reservoir performance in well conditions so that the purpose of reservoir simulation is to determine the current and future reservoir performance to estimate the rate of oil production (production forecast rate). Rapid technological developments encourage experts to create computer software that is used as a simulation tool. The method in this study uses reservoir modeling simulation software. The production forecast rate in this reservoir model is carried out for 2 years by only adding one production well in the reservoir area that has not been drained, namely infill well A. This shows that the oil production rate continues to decrease but increases the cumulative oil production. The cumulative oil production produced by well A was 33,80 STB in 2014 with an average increase of 12%. Therefore, it is necessary to evaluate the reservoir model after 2014 in detail the value of the data again so that the reservoir simulation process for the next forecast gets good oil production results.

Abstract Wireline Logging is the activity of collecting and recording data on physical parameters according to the depth of the borehole during the drilling process. The measured data are radioactivity, speed of sound and electromagnetic. Methane gas trapped in coal or commonly referred to as Coalbed Methane is one of the alternative energy sources where the existing conventional gas has decreased production and no other new gas fields have been found. The Muara Enim Formation, which is the main target of mining companies, contains abundant brown coal or lignite from the South Sumatra region. The existing log data will be interpreted and evaluated qualitatively and identified the presence of the coal seam using wireline logging. Coalbed methane or CBM is an alternative energy source that can be utilized. The gas trapped in the coal seam will be utilized, because this research will identify the coal seam by using a wireline logging tool in well AB field X. Through the interpretation of logging results using gamma ray log data and density log data from several zones in the same location . Gamma ray log data and density logs will detect coal seams because there is a radioactive element in the coal, namely potassium. With a low gamma ray log value and a low density log value, it will be possible to have a coal seam in well AB field X. Keywords: Coal, CBM, Wireline Logging Abstrak Wireline Logging adalah kegiatan pengumpulan dan perekaman data parameter-parameter fisika sesuai kedalaman dari lubang bor selama proses pengeboran berlangsung. Data yang diukur adalah radioaktivitas, kecepatan suara dan elektromagnetik.Gas metan yang terjebak di dalam batubara atau biasa disebut dengan Coalbed Methane merupakan salah sau energy alternative yang dimana gas konvensional yang ada mengalami penurunan produksi dan belum ditemukan lapangan-lapangan gas baru lain nya. Formasi Muara Enim yang menjadi target utama dari perusahaan tambang yang didalamnnya terdapat batubara coklat atau lignit yang melimpah dari wilayah Sumatera Selatan. Data Log yang ada akan diinterpretasikan dan di evaluasi secara kualitatif dan di identifikasi keberadaan lapisan batubra dengan menggunakan wireline logging. Gas yang terjebak didalam lapisan batubara akan dimanfaatkan, karena hal itu penelitian ini akan mengidentifikasi lapisan batubara dengan menggunakan alat wireline logging pada sumur AB lapangan X. Melalui interpretasi hasil logging dengan menggunakan data log gamma ray dan data log density dari beberapa zona di lokasi yang sama. Data log gamma ray dan log density akan mendeteksi lapisan batubara karena didalam bautbara terdapat unsur zat radioaktif yaitu kalium. Dengan nilai log gamma ray yang rendah dan nilai log density yang rendah akan memungkinkan ada nya lapisan batubara didalam sumur AB lapangan X.

Salah satu tujuan yang sangat penting dalam penyelesaian sumur adalah mendapatkan hasil penyemenan yang baik, akan tetapi pekerjaan penyemenan (primary cementing) yang dilakukan tidak selalu berjalan dengan lancar seperti yang direncanakan. Penyemenan merupakan pekerjaan yang membutuhkan biaya yang cukup besar dan resiko yang tinggi dalam mengerjakannya, dan masalah – masalah pada pekerjaan penyemenan diantaranya yaitu : channeling, microannulus, dan freepipe. Sebagai solusi menangani masalah tersebut yaitu dengan dilakukannya pekerjaan squeeze cementing. Squeeze cementing ialah penyemenan kembali yang dikerjakan untuk salah satu cara perbaikan sumur dengan menginjeksikan bubur semen dengan volume yang kecil pada zona atau area yang terdapat masalah, dalam tugas akhir ini metode yang dipilih adalah metode balance plug. Pemboran sumur X bertujuan sebagai tempat penambahan area resap hidrokarbon dilapisan reservoir Batupasir TAF. Dari hasil Pemboran sumur – sumur lapangan Z yang ada telah dinyatakan dapat memperoleh hidrokarbon dari lapisan batupasir pada lapisan TAF-2, TAF3.1, TAF-3.2, TAF-3.3 dan TAF-4. Sumur usulan diperkirakan menembus bagian puncak reservoir tersebut, dan dibor directional dari cluster JAS-C sampai total kedalaman 3250 mTVDSS/3400.93 mD (Total Depth). Pada proses logging pertama setelah dilakukannya primary cementing didapatkan hasil data log dari logging Cement Bond Log (CBL) dan Variable Density Log (VDL) yang menunjukan bahwa adanya kejanggalan, masalah, atau sesuatu yang tidak baik pada data log. Terlihat adanya kenaikan nilai amplitudo sebesar 70 – 80 mV dan grafik yang tinggi pada kedalaman 2460.63 ft – 2624.67 ft yang menunjukan adanya freepipe pada area tersebut, maka dari itu perlu dilakukannya secondary cementing yaitu squeeze cementing dengan tujuan untuk memperbaiki primary cementing yang bermasalah supaya tidak terjadi hal – hal yang tidak diinginkan.

Abstract In an effort to lift oil and gas from a subsurface reservoir, companies engaged in oil and gas must carry out production operations. The production operation itself aims to make oil and gas produced or lifted to the surface. However, the problems faced to carry out maintenance in this production operation are not small and can even be categorized as a very expensive job. In order to reduce the budget of production operations there needs to be efficien by doing good maintenance and observation. One aspect that needs to be considered in the maintenance of production operations is the appropriateness of the equipment. This determination of feasibility greatly influences the cost of production operations due to maintenance, and observation is one of the most expensive part of production operations. Therefore it is necessary to have the right assessment and observation before deciding that the pump equipment used is suitable and efficient. In this study aims to evaluate the feasibility of surface and downhole pump equipment related to lower pump efficency. It is expected to be used as suggestions and consideration to evaluate the performance and safest downhole pump equipment. Keywords: production, downhole pump, production operations, production equipment Abstrak Dalam usaha untuk mengangkat minyak dan gas bumi dari reservoir, perusahan yang bergerak di bidang minyak dan gas harus melakukan operasi produksi. Operasi produksi ini sendiri bertujuan agar minyak dan gas bumi dapat diproduksikan atau di angkat kepermukaan. Namun permasalahan yang dihadapi untuk melakukan perawatan pada operasi produksi ini tidaklah sedikit bahkan bisa di kategorikan suatu pekerjaan yang sangat mahal. Oleh karena itu untuk menekan budget dari operasi produksi perlu adanya efisiensi dengan melakukan perawatan dan pengamatan yang baik. Salah satu aspek yang perlu diperhatikan dalam perawatan dalam operasi produksi adalah kelayakan equipmentnya. penentuan kelayakan ini amatlah berpengaruh pada biaya operasi produksi karena perawatan, dan pengamatan merupakan salah satu point yang paling mahal pada operasi produksi.

Well X is located in the offshore Y field, where there are 7 production wells, all of which use an artificial lift in the form of a gas lift. In this field, oil is produced from the N oil layer while the gas layer comes from the K layer. Well X was drilled in May 2013 with a target of N oil formation at a depth of 9,007 ft MD, slope (450) and 4-1/2" Liner completion. The initial production of well X was 1,632 BOPD; 5.3 MMSCFD; 0% BSW. Well X is the only well in the Y offshore field that does not penetrate the K gas formation, so gas production from nearby wells is used to produce oil from the N formation. well-to-well gas lift. Along with production time, the reservoir pressure in the N oil layer and K gas layer has decreased, so that oil production in well X has also decreased. With changes in company policy that optimize and increase gas production to increase gas sales to the industry around the company's operational areas since early 2017, the outgoing pressure on the Y platform has increased from 210 psi to 450 psi, causing a total oil well X could not pass through and produce due to high outgoing pressure on platform Y. Well X's last production data was on January 31 2017 with oil production of 179 BOPD and 1.25 MMSCD for gas production and gas lift injection of 0.75 MMSCFD, before finally shutting down. The selection of another artificial lift as a substitute for the gas lift has been carried out to revive well X later. Based on the alloy table made by Weatherford for the selection of artificial lifts for conditions on the Y field platform, ESP has many advantages and appropriate flexibility compared to other types of artificial lifts. The ESP type D1050N which is a mix flow ESP has been selected and after installation in well X in August 2019 it has successfully revived with a production test of 885 BFPD, 681 BOPD, and 23% water content on September 3 2019. ESP in well X has been in production for 2 years, until finally experiencing a leaky tubing problem in September 2021 and requiring a new tubing replacement job along with a new ESP replacement to revive the X well.

This study aims to evaluate how the Russian-Uk rainian war affects world crude oil prices. This conflict plays a significant role in disrupting the production and supply of crude oil in the Black Sea region, which could affect the global supply of crude oil. The evaluation method used is an analysis of the latest literature and economic data. The results show that the Russia-Uk raine war had a significant impact on world crude oil prices, although other factors such as oversupply and reduced demand due to the COVID-19 pandemic also play an important role in determining crude oil prices. Therefore, it is necessary to carry out a holistic and continuous evaluation of the various factors that affect world crude oil prices, including regional or geopolitical conflicts. This study provides a better view of how the Russo-Uk rainian war affected world crude oil prices and provides suggestions for a more comprehensive evaluation in the future. Based on the results of this research, it is hoped that it can become information and input for lecturers, researchers, practitioners, and all interested parties at the Faculty of Engineering, Bhayangk ara University, Jak arta Raya.
