Abstract

Faktor emisi metana (CH₄) dari pabrik kelapa sawit (POM) di Indonesia merupakan salah satu penyebab utama peningkatan gas rumah kaca yang berkontribusi terhadap perubahan iklim. Untuk mengatasi permasalahan ini, penelitian ini menerapkan machine learning berbasis data satelit guna mendeteksi dan menganalisis pola emisi metana secara otomatis dan efisien. Data yang digunakan diperoleh dari GHGSat, Sentinel-5P TROPOMI, PRISMA, EnMAP, dan EMIT, yang menyediakan informasi spasial dan temporal mengenai distribusi metana di atmosfer. Data ini diproses menggunakan Google Colab, dengan tahapan pembersihan, normalisasi, transformasi variabel, dan seleksi fitur sebelum dilatih menggunakan beberapa model machine learning, yaitu Logistic Regression, XGBoost, Gradient Boosting, Decision Tree, dan K-Nearest Neighbors (KNN). Hasil evaluasi menunjukkan bahwa XGBoost memiliki performa terbaik, dengan akurasi 73.53% dan F1-score 52.28% untuk wilayah dengan emisi tinggi, diikuti oleh Decision Tree dengan akurasi 73.44% dan recall 54.90%. Model lainnya, seperti Logistic Regression dan KNN, menunjukkan hasil kurang optimal dengan recall rendah, yang menyebabkan banyak sumber emisi tidak terdeteksi. Dengan metode ini, deteksi emisi metana dapat dilakukan lebih cepat, akurat, dan dalam skala luas, sehingga mendukung strategi mitigasi perubahan iklim serta keberlanjutan industri kelapa sawit di Indonesia.

Abstract

Sumur WY-31 merupakan sumur hidrokarbon baru yang telah berproduksi selama 97 jam. Oleh karena itu, perlu dilakukan uji sumur pada sumur WY-31 untuk mengetahui karakteristik dan kemampuan produksinya. Pada penelitian ini, dilakukan uji sumur menggunakan pressure build-up (PBU) test dengan metode analisis Pressure Derivative. Tahap pertama melibatkan PBU Test dengan produksi selama beberapa waktu, kemudian sumur ditutup. Hal ini bertujuan untuk mengamati respons tekanan dasar sumur terhadap gangguan. Data yang diperoleh berupa tekanan dan laju alir dasar sumur dianalisis untuk menentukan karakteristik dan parameter produktivitas reservoir, seperti permeabilitas, skin factor, flow efficiency, radius investigasi, boundary reservoir, dan productivity index (PI). Hasil analisis menunjukkan nilai tekanan ekstrapolasi (P*) sebesar 891 psia, permeabilitas 718 mD, skin -1.87, ΔPskin -25 psia, radius investigasi 389.76 ft², productivity index ideal 3.59 bbl/d.psi, productivity index aktual 5.4 bbl/d.psi, flow efficiency 1.4, serta laju alir maksimal 353.27 BOPD yang dihitung menggunakan persamaan Standing. Berdasarkan fitting pada kurva Pressure Derivative, reservoir sumur WY-31 bersifat homogen dengan boundary model parallel fault. Nilai skin negatif mengindikasikan perbaikan formasi di sekitar sumur, serta adanya kenaikan tekanan selama produksi. Kenaikan tekanan ini menyebabkan PI aktual lebih besar daripada PI ideal. Dengan demikian, produksi di masa depan diperkirakan lebih tinggi dari yang diharapkan.

Abstract

This study investigated the use of Xanthan gum as an additive to improve the rheology of drilling mud. The parameters used in this rheology are viscosity, yield point, shear stress, and gel strength. This experiment was conducted in the laboratory to evaluate the effects of bentonite, fresh water, and Xanthan gum additives at various concentrations. During the experiment, five drilling mud samples containing 1, 3, 5, 7, and 15 grams of Xanthan gum were prepared. In the sample containing 1 gram of Xanthan gum, the viscosity was measured for 120 seconds/quarter, the yield point was found to be 24 lb/100ft², the plastic viscosity was found to be 4 cp, and the gel strength was found to be 0.78 lb/100ft². Meanwhile, the sample containing 15 grams of Xanthan gum has a viscosity of 4800 seconds/quarter, a plastic viscosity of 20 cp, a yield point of 52 lb/100ft², and a gel strength of 1.3 lb/100ft². The final result shows that the increase in the rheological properties of the mud is due to Xanthan gum which is in accordance with API standard drilling.

Abstract

The goal is to drill an MFA well down to 4593 feet (MD) in the NKL field. At a depth of 4593 feet, the MFA well had a well kick problem as a result of drilling into the high pressure formation zone while gas was present in the formation. Gas bubbles in the soil are a sign that the MFA well has kicked. Correct handling of this well kick issue is necessary to avoid blowout. Well kick countermeasures on the MFA well in the NKL field are evaluated using the concurrent method, which includes collecting data from drilling implementation reports, analyzing new mud (kill mud) weight, maximum allowable mud weight (maximum allowable mud weight), pump, and formation pressure calculations when a well kick occurs. Make an evaluation by comparing the results of the calculation with the implementation data from the field, and then make inferences. The evaluation of the well kick countermeasures' implementation using the concurrent approach revealed that the kill mud weight was 12.21 ppg. The muck had to be moved using 2208 pump strokes and 36.79 minutes of pumping time. When the mud pump is stopped and the SIDP price is zero, there is no flow in the annulus, indicating that the well kick has been managed well. The most effective method for developing well-thought-out countermeasures is the concurrent strategy.

Abstract

Optimizing artificial lift systems according to well conditions is essential to achieve the desired production rate. Continuous production often leads to declining flow rates and reservoir pressure, causing incomplete fluid recovery. Water injection helps maintain pressure, while workover operations enhance production rates. This study optimizes well "E-030" by redesigning the artificial lift system from a Sucker Rod Pump (SRP) to an Electrical Submersible Pump (ESP) post-workover. The goal is to evaluate pre-workover production, justify the workover, and assess the redesigned lift system's efficiency. Initially, well "E-030" used an SRP. Due to a water flooding project, a workover was conducted, adding production layers to boost capacity. The best artificial lift post-workover was determined using an Inflow Performance Relationship (IPR) curve, applying Wiggin's method to analyze well conditions. The post-workover IPR analysis showed a maximum flow rate of 1104 bfpd and an optimal rate (Qopt) of 883 bfpd, a significant increase from 145 bfpd pre-workover. This led to replacing the SRP with an ESP to accommodate higher production. The redesigned ESP system includes a REDA D725N pump, a REDA 456 series motor, and AWG#4 cable, improving production efficiency.

Abstract

Over time the flow rate will decrease so that the reservoir pressure will decrease, so it is necessary to optimize or increase the flow rate. To overcome the above, an artificial lift is used or what is called an “Artificial Lift”. Artificial Lift is an artificial lift method that is useful for adding pressure to the fluid so that it can flow up to the surface. At this well, the initial Artificial lift Design is being carried out using ESP (Electrical Submersible Pump) to become a Gas lift with the Continuous flow method. The purpose of this analysis is to see the potential installation of a continuous flow gas lift in the “F-1” well. The result of the IPR curve analysis from the calculation show that the “F-1” well has a maximum flow rate of 6704.7 bfpd. So that the well can still be optimized with the Gas lift design. Based on the Gas lift design, the desired flow rate is 5300 bfpd. In the F-1 well, it is known that the injection gas is 1,355,600 scf/day. As well as the location of the depth of valve 1 is at a depth of 2100 ft, valve 4 is at a depth of 2500 ft, valve 5 is at a depth of 2850 ft ( operation valve), and additional valves can be installed BE1 at 2344 ft and BE2 at 2489 ft.

Abstract

Well X is one of the gas wells owned by PT Pertamina EP Cepu Donggi Matindok Field, with the ongoing gas production process, the reservoir experiences a decrease in pressure over time which affects the productivity of the well so that the production rate of the well can decrease. In conditions where the pressure continues to decrease, it will cause the flow rate to no longer be able to lift the fluid, this is called liquid loading.The purpose of this study is to analyze and calculate the minimum flow rate and calculate the future IPR. The problem limitation in this study is emphasized on the analysis of well X to determine the minimum flow rate value and the minimum flow rate value when there is a decrease in pressure in the well. The method used is the Turner method in calculating the critical flow rate and the LIT calculation method in calculating the future IPR to determine the shape of the IPR curve in the future. The results of the calculation of the minimum flow rate of well X vary depending on the size of the Casing or tubing through which the fluid passes, at 7"Casing of 11.64 MMscfd, at 4.5" Casing of 4.87 MMscfd, and 3.5" tubing of 2.5 MMscfd. Based on the results of the IPR curve correlation with OPR using commercial software, using a choke size of 0.5625 inches with the actual flow rate obtained of 12.38 MMscfd.
