Microbial Enhanced Oil Recovery (MEOR) is a tertiary methods to increase oil production using bioproduct of microorganisms form acidic compounds, gases, polymers, and surfactants, as an agent that can alter the characteristics of the reservoir rock and oil. Previous laboratory research indicated that bacterial isolates indigen from petroleum reservoir, MSD4 and MSD5, with the amount of inoculum ratio 1:1 in recovery medium can reduce the viscosity value and interfacial tension of oil. The aim of this research was to determine the amount of oil recovery from low saturated oil in limestone artificial core by using bacterial core flooding method, also to determine the physical character and chemical character changes in limestone rocks and petroleum. Each bacteria, MSD4 and MSD5, were adapted to the medium SMSS that have been added by 5% oil. Inoculum of indigen bacterial cultures to be injected into the limestone core was bred in the SMSS culture medium added molasses with a varied amount, as much as 1%, 2%, and 3%. From the those variation, the amount of molasses added as much as 1% in the medium SMSS, is known that MSD4 and MSD5 cultures can grow to the highest μ respectively at the age of 16-hour and 24-hour with a value at 0.9992 hours-1 and 0, 9993 hours-1. Inoculum MSD4 and MSD5 cultures with the amount of 1:1 ratio and each bacterial cell density 107-108 cells/mL, were injected into artificial limestone cores with oil saturated less than 15%. The value of rock porosity range used for the simulation of bacterial flooding is 37% -42%, while permeability range used low permeability value (1mD-10mD) and fair permeability value (10mD-50mD). High oil recovery factor (RF%) were obtained from bacterial flooding simulation and incubated for 7 days in a temperature of 55°C on medium SMSS for cores with low permeability values and fair, has a range of 16,3% - 32% and 12% -15,3%. The result of microorganisms activity in limestone rocks from a change on physical character, have a range at -41,8% - 698% on permeability value and a range at -63,85% - 1,03% on porosity value. Indicator of bacterial attachment on limestone cores can be determined by photomicrographs analyzing Scanning Electron Microscope and Energy Dispersive X-ray Spectroscopy.

Metode EOR merupakan salah satu cara yang biasa dipergunakan agar produksi minyak dari suatu reservoir semakin meningkat. Salah satu metoda EOR yang biasa dipergunakan yaitu injeksi surfaktan. Fungsi injeksi surfaktan ini shingga nanti terjadi penurunan IFT (Interfacial Tension) minyak dengan air sehingga nanti berkurangnya tekanan kapiler di daerah penyempitan pori-pori sehingga minyak yang tersisa di daerah mendapat pengaruh dari tekanan kapiler itu agar bisa didorong untuk berikutnya bisa dilakukan produksi. Dalam tugas akhir ini akan dibahas mengenai pengaruh surfaktan dengan penambahan air kulit nanas terhadap perolehan minyak yang paling optimal. Salinitas yang dipergunakan untuk tugas akhir ini beragam, yaitu 4000 ppm dan 15000 ppm. Dari kedua salinitas tersebut selanjutnya dicampurkan dengan surfaktan AOS dengan konsentrasi masing-masing 2,5 %, dan 3 % dan penambahan larutan air kulit kulit nanas sebanayak 10%, selanjutya akan di lakukan uji fisik berupa pengukuran IFT, viskositas, dan juga densitas. Setelah dilakukan pengukuran tersebut maka selanjutnya merupakan proses saturasi dan injeksi. Selanjutnya melakukan perbandingan RF yang didapatkan dari menetapkan konsentrasi dan salinitas mana yang teroptimal terhadap tiap larutan salinitas itu.

Produksi sumur minyak mengunakan artificial lift electric submersible pump memiliki beberapa keterbatasan, salah satunya adalah gas yang terproduksi bersama dengan minyak, gas yang terproduksi bersama dengan minyak dapat menurunkan nilai head dari pompa electric submersible pump. Sumur pada penelitian kali ini memproduksi minyak ringan dengan nilai GOR yang tinggi, peningkatan nilai GOR membuat desain electric submersible pump yang terpasang tidak mampu mempertahankan jumlah produksi yang ditentukan, untuk itu dilakukan penelitian mengenai pengaruh head degradation terhadap laju produksi pada sumur ESP dengan GOR tinggi. Penelitian ini menggunkan variabel nilai GOR 3000 scf/stb. Sumur ini mampu untuk berproduksi maksimum 8202,2 STB/day, sehingga laju produksi yang ditentukan sebesar 6600 STB/day. Saat ini telah terpasang pompa ESP tipe Reda S8900N. Hasil desain pada GOR 3000 pompa S8900N tidak mampu untuk berproduksi sesuai yang ditentukan maka dilakukan pergantian pompa Reda H15500N 155 stage dan membutuhkan intake gas separator 80%. Berdasarkan hasil analisis terjadi penurunan head pompa atau head degradation akibat nilai GOR.

Reservoir X is located in West Tanjung Jabung Regency, Jambi, Indonesia, with initial pressure is 2,028 psia, and a temperature is 226°F. The reservoir has been produced from February 2018 to the present (February 2021), with cumulative gas production of 5.17 Bscf. Based on the Plan Of Development (POD) study in 2016, the initial gas in place was determined volumetrically to be 49,92 Bscf. To compare the initial gas in place, it is deemed necessary to recalculate the initial gas in place by utilizing another method. The calculation of Initial Gas In Place (IGIP) is conducted by using the P/Z method. In this method, the Initial Gas in Place is obtained 49.01 Bscf. Based on analyzing the phase diagrams and the prevailing reservoir conditions, reservoir X indicated a dry gas reservoir. Such reservoir drive mechanism is a depletion drive, determined from the P/Z vs Gp plot, generating a straight line. Based on the assumed abandonment pressure value of 300 psia, the estimated ultimate recovery value is 41.93 Bscf, with the recovery factor value of 87.65% and the remaining reserves of 36.76 Bscf.

Indonesia is a developing country that still depends on fossil fuels. Natural gas is one of the energy sources used as an alternative fuel for Indonesia's future to support national energy needs. This is because the amount of natural gas reserves in Indonesia are still classified as safe for the next several decades with increasing demand. The government has imposed a gas price for industry of USD $ 6 per MMBTU in accordance with the implementation of Presidential Regulation Number 40 of 2016 concerning Natural Gas Pricing. This strategic policy is believed to be able to boost the competitiveness of the domestic manufacturing sector so that it will make a significant contribution to the national economy. However, on the business entity side, this policy is considered to be detrimental because it is still unclear about the government intensive that is given to business entities. The purpose of this study is to analyze a case regarding the determination of the downstream selling price of natural gas for industrial costumers which should be in accordance with the parameters of the downstream selling price of natural gas. The results (output) obtained from this study indicate the process of optimizing the selling price of natural gas in downstream business activities to obtain the ideal value.

Waterflooding is one of the most effective methods to improve oil recovery in mature fields because of its high success ratio, easy in application and cost efficiency. Development until now has shown that Capacitance Resistance Model (CRM) can be used as alternative from reservoir model and simulation studies. CRM can be used as model to predict reservoir characterization and reservoir performance quickly and accurately with only require historical production and injection data. CRM characterizes the reservoir by calculating the connectivity value and the response delay between the injections well and the production well as unknown parameters. Pandhawa Field is a heterogeneous carbonate reservoir with an average permeability of 65 mD with peripheral waterflood since 20 years ago. By knowing the injection efficiency, the optimization process can be carried out by increasing the water injection rate in injection wells that have high efficiency and vice versa. In this study, the performance of waterflood is analyzed using the Capacitance-Resistance Injection-Production Model (CRM-IP) to determine the connectivity of each injection and production well. This study also discuss CRM-IP implementation on MATLAB programming language and optimization of injection rate allocation for the most optimum cumulative oil production. Result of this study indicate total additional oil 505 MBO will be obtained during 120 months period by conduct redistribution water injection management for each injector. By using CRMIP methodology, waterflood management in this field can be done much faster, therefore decision taken for this field will be more effective.
