Abstract

Oil-based drilling muds are effective in protecting formation integrity and resisting high temperatures, but additives are necessary to optimize their performance. This study proposes using potato starch as an additive to improve the performance of oil-based drilling mud. Potato starch was chosen because of its ability to act as a viscosifier or thickener that remains unaffected by water salinity. The research involved adding different concentrations of potato starch to a fresh oil-based drilling mud, with two Oil-to-Water Ratio (OWR) ratios, 75:25 and 80:20, employed for the two trials. Rheological testing was utilized to assess the influence of potato starch additives on the viscosity, gel strength, plastic viscosity, and yield point of drilling mud. The findings showed that the incorporation of potato starch in oil-based drilling mud can enhance its rheological values. Using potato starch as an additive offers the potential to tackle wells that have formation conditions that are brittle and sensitive to water and high temperatures. This research provides novel insights into the development of more effective and eco-friendly drilling mud formulations.

Abstract

Kegiatan karakterisasi reservoir memiliki peran yang penting untuk dapat mengidentifikasi sifat-sifat batuan dan fluida, serta dapat mengestimasi besar cadangan hidrokarbon dibawah permukaan. Estimasi metode tradisional memiliki akurasi yang rendah, sangat memakan waktu, dan kesalahan yang lebih besar selama memprediksi porositas dan permeabilitas reservoir menggunakan data well logging serta pengukuran sample core yang cukup memakan biaya. Dalam penelitian ini, metode machine learning Random Forest diterapkan sebagai solusi yang cepat, hemat biaya untuk mengestimasi parameter reservoir dari data well logging. Enam model telah dikembangkan pada kondisi yang berbeda (jumlah fitur dan transformasi data) yang dibagi menjadi 85% training data dan 15% test data. Penentuan hyperparameters merupakan hal yang penting dikarenakan akan sangat berpengaruh ke performa pada setiap model. Hasil Exploratory Data Analysis menunjukkan bahwa fitur-fitur yang dapat digunakan sebagai input data untuk memprediksi nilai porositas core adalah fitur GR (-0.54), RHOB (-0.51), LLS (-0.44), LLD (-0.4), dan CXO (0.32). Sehingga dilanjutkan kedalam proses pelatihan model dan ditemukan bahwa model B dengan fitur tiga teratas (GR, RHOB, dan LLS) tanpa transformasi data mendapatkan hasil yang optimal dengan mendapatkan nilai R2 sebesar 0.8 dan RMSE sebesar 0.034 dengan menggunakan hyperparameter n_estimators=19 dan random_state=42. Penelitian dilanjutkan dengan melakukan pelatihan model ulang dengan menggunakan seluruh data well logging untuk dapat mengembangkan model prediksi porositas. Prediksi porositas core berhasil dilakukan hingga 1393 data pada baris kosong yang terdapat pada kolom porositas core.

Abstract

Lapangan HRD adalah lapangan salah satu lapangan minyak dan gas yang paling tua yang terletak di Offshore Delta Mahakam, Indonesia. Semua hidrokarbon terakumulasi pada reservoir kompleks yang terdiri dari banyak lapisan, di mana minyak, gas dan tekanan reservoir yang berbeda setiap saat. Integrated Production Modelling dengan menggunakan simulator GAP menawarkan teknik yang efektif dalam memperkirakan performa sumur yang mana diproduksi dari reservoir multifasa dan tekanan yang bervariasi. Integrated Production Modelling mampu mengelola dengan baik kompleksitas reservoir, skenario produksi yang bermacam - macam bentuknya, dan juga dengan keterbatasan fasilitas produksi di permukaan. Salah satu kelebihan dari GAP adalah dapat membuat produksi dari bermacam – macam reservoir multifasa yang digabungkan dalam satu bentuk Network Simulation tentunya dengan data PVT yang berbeda – beda, yang mana respon dari satu sumur dapat mempengaruhi produksi sumur yang lainnya. Tujuan utama dari penggunaan GAP adalah untuk mendapatkan respon penuh dari Lapangan Hidrokarbon dengan menggunakan sifat fisik dari setiap data yang pastinya dapat mempengaruhi produksi. Melalui proses Integrated Production Modelling ini, Sumur Lapangan HRD di Zona Lower dan Deep berhasil memberikan tambahan produksi sebesar 0.15 MMbo dan memberikan justifikasi kebutuhan Gas Lift Network di Lapangan HRD. Singkatnya, Model ini memberikan optimasi ekonomi dari minyak dan gas yang terproduksi.

Abstract

Penelitian ini bertujuan untuk menganalisis rata-rata ukuran lubang bor (Average Hole Size) pada sumur Sonos A15 serta mengevaluasi kebutuhan aktual volume semen berdasarkan hasil perhitungan hidraulik dan geometri lubang bor. Data diperoleh dari laporan lapangan serta hasil pemantauan oleh Mud Engineer dan tim Mud Logging. Analisis dilakukan terhadap konfigurasi casing, open hole, dan rangkaian pipa (Bottom Hole Assembly/BHA) dengan menggunakan pendekatan matematis berbasis volume silinder dan efisiensi pompa. Hasil menunjukkan bahwa diameter aktual lubang bor mengalami pelebaran dari 8.5 inci (ukuran bit) menjadi 8.88 inci. Akibatnya, volume ruang annulus meningkat dan berdampak pada bertambahnya kebutuhan semen dari nilai teoritis sebesar 33.38 bbl menjadi 44.75 bbl. Perbedaan ini menegaskan pentingnya evaluasi aktual ukuran lubang dalam perencanaan program penyemenan untuk menghindari kekurangan slurry saat operasi berlangsung.

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

Oil production from a well often decreases due to reduced reservoir pressure, so a production increase method or artificial lift is needed to maintain or increase the production flow rate. One of the commonly used artificial lift methods is the Electrical Submersible Pump (ESP). This study aims to design an optimal ESP system for the DT014 well, which is experiencing decreased production. The analysis was carried out by considering reservoir parameters, fluid characteristics, and well operating conditions. The design process includes the selection of pumps, motors, and electrical cables that are in accordance with production needs. Simulations were carried out to ensure the performance of the ESP in increasing oil production efficiently and economically. The design results show that the application of ESP to the DT014 well can significantly increase the production flow rate compared to previous methods. By considering pump efficiency and energy consumption, the selection of the right ESP can maximize production while minimizing operational costs. Thus, the implementation of ESP has proven to be an effective solution to increase oil production in wells experiencing decreased reservoir pressure. This study is expected to be a reference for the optimization of artificial lift systems in oil fields with similar conditions.

Abstract

Hydrocarbon production forecasting is the process of projecting oil or gas production over a period of time. One commonly used method is production modeling with Decline Curve Analysis (DCA). Many previous studies have used the Trial Error and Chisquare test method in DCA. However, this method has limitations including: long calculation time, modeling is done manually and not automatically, and the fit of the production curve with the data is often inaccurate. To overcome these limitations, a method that is fast, automatic and produces accurate curves with data is needed. One of them is the Levenberg-Marquardt Algorithm (LMA) numerical optimization approach. The Levenberg-Marquardt Algorithm method is an iterative method used to solve nonlinear optimization problems. The Levenberg Marquardt Algorithm method has advantages such as: reliability, fast convergence, and has been widely applied in engineering optimization problems. This study aims to forecast hydrocarbon production, calculate EUR (Estimated Ultimate Recovery) and ERR (estimated remaining reserve) at well HS-0105 AG field. First, a DCA program based on LMA was developed with the MATLAB programming language. After that, the production data is inputted into the LMA program to do production modeling until the optimum curve is obtained. After obtaining the optimum DCA curve, a comparison was made with the curve resulting from trial and error. From the results of DCA curve optimization with LMA, the RMSE (Root Mean Square Error) value = 101,756, R2 (R-squared) value = 0,574, computation time 2-3 seconds in the Levenberg-Marquardt Algorithm (LMA) method while the Trial Error and Chisquare test method RMSE (Root Mean Square Error) value 128.905 R2 (R squared) value = 0.569 and long computation time. From the comparison results, the Levenberg-Marquardt Algorithm (LMA) method is much better than Trial Error and is recommended for use. Based on the Decline Curve Analysis with the Levenberg-Marquardt Algorithm (LMA) method, the EUR (Estimated Ultimate Recovery) value is 14339,525 STB and the ERR (estimated remaining reserve) value is 7693,091 STB at the HS-0105 well in the AG field. With the results of this projection, it is expected that the production of the HS-0105 well in the AG field can be stimulated to withstand the rate of decline in production and even increase.
