Abstract

The Bintuni Basin is one of the largest hydrocarbon-bearing basins in Eastern Indonesia, although only a limited number of oil and gas fields are currently. Consequently, further investigation into its petroleum system, particularly the potential of its source rocks. In hydrocarbon exploration, characterizing source rock is critical to evaluating the presence of organic-rich strata capable of generating hydrocarbons. Geochemical analysis is a widely used method for assessing source rock potential, utilizing total organic carbon (TOC), rock-eval pyrolysis, and vitrinite reflectance data. In this study, geochemical data were obtained from one well and two outcrop samples to evaluate the quantity, quality, and thermal maturity of organic matter. The geochemical assessment of rock samples from four stratigraphic formations indicates that the Permian Ainim Formation exhibits the highest source rock potential. TOC values range from 1% to 80% with hydrogen index (HI) values range between 13 and 431 mg HC/g TOC classifying the formation as a good to excellent potential. The dominant organic matter consists of kerogen type II/III suggesting the potential for both oil and gas generation. Thermal maturity analysis indicates that the Ainim formation has reached the oil and gas generation window at depths of 8,075–8,420 feet. These findings demonstrate that the Ainim Formation represents a significant source rock within the Bintuni Basin, contributing valuable insights into the region's petroleum system and hydrocarbon prospectivity.

Abstract

The length of time to produce reservoir fluid will definitely experience a decrease in the production rate. The decrease in production rate can be caused by inappropriate tubing sizes and Damage to formations that impede fluid flow.To overcome the decline in production rates, it is necessary to choose the appropriate tubing size and carry out acidizing activities. Appropriate tubing size can avoid pressure drop and extend the life of the well. Acidizing is the injection of acid to eliminate the effect of decreasing permeability. The tubing size of 2 7/8 inches is not suitable for the “REDD-24” well because the target Qopt value of 130.997 bfpd was not achieved and there was an indication of calcium carbonate scale in the formation. This study discusses production optimization by re-designing tubing id after acidizing. Calculating the inflow performance relationship (IPR) using the Wiggin's method and obtaining Qtmax results of 163.74583 bpd, calculating theProductivity Index (PI) of 0.0870911 psi which according to Kermit E. Brown, the PI value is classified as low, calculates the skin value and obtains the results (+) 37.35 which indicates that the formation of the "REDD-24" well has suffered formation Damage.

Abstract

This study aims to evaluate the effect of 3% fracseal addition on the rheological properties and filtration characteristics of drilling mud at temperatures of 80°F, 130°F, and 180°F. The research was conducted experimentally through laboratory testing of plastic viscosity, yield point, gel strength at 10 seconds and 10 minutes, and filtration loss based on API RP 13B-1 standards. The results indicate that standard drilling mud experienced rheological degradation with increasing temperature, characterized by reduced plastic viscosity, excessive gel strength, and increased filtration loss. In contrast, the addition of fracseal improved rheological stability, increased yield point, and reduced filtration loss up to 180°F. These findings suggest that fracseal functions not only as a lost circulation material but also as a rheological stabilizing additive for high-temperature drilling operations.

Abstract

The research aims to analyze the influence of clay mineral composition on the thermal evolution of source rock in the South Balikpapan area, Balikpapan City, East Kalimantan. Mudstone samples were analyzed by vitrinite reflectance (Ro), X-ray diffraction (XRD) and scanning electron microscopy (SEM). XRD analysis results show that the predominant clay minerals in the mudstone are mixed illite/smectite (35-42%), kaolinite (30-39%), illite (18-23%), and chlorite (5-10%). The predominant mineral presence of illite/smectite indicates a high heat retention capability. This plays an important role in the process of diagenesis and thermal transformation. High heat retention allows for localized temperature increases that further influence the thermal evolution of the host rock. The kaolinite mineral, which reaches 30-39%, contributes to the thermal stability of the host rock due to its inert nature in the medium temperature range. Meanwhile, the presence of illite minerals (18-23%) also supports thermal stability but with a smaller role than kaolinite. Otherwise, chlorite (5-10%) can increase the chemical reactivity of minerals under high temperature conditions, potentially triggering mild metamorphic reactions in rocks. The Ro values obtained from the samples range from 0.33% to 0.47%, which indicates a low to medium level of thermal maturity. This maturity level indicates that the mudstone rocks in the South Balikpapan area have not reached the optimal condition to produce hydrocarbons. These vitrinite reflectance values correspond to the estimated maximum temperature that the rocks have experienced, which is likely not high enough to trigger the formation of significant amounts of oil or gas.

Abstract

Shale formations in the 8 ½” section of MKLS Well in East Kalimantan present drilling challenges due to their reactive nature at high temperatures up to 250°F. The interaction between water-based mud and clay minerals can cause swelling, sloughing, and bit balling, which increase Non-Productive Time (NPT) and operational risks. This study aims to evaluate the effectiveness of a High Performance Water-Based Mud (HPWBM) system based on KCl–Polymer Polyamine in mitigating these risks. Testing included mud property evaluation, Linear Swelling Meter (LSM), Erosion Test, and Accretion Test using shale cuttings from MKLS Well. Results show a mud density of 1.36 g/cc, plastic viscosity of 15 cP, yield point of 25 lb/100 ft², filtrate loss of 4.8 mL/30 minutes, and pH of 9.40. Swelling of 3.5% (72 hours), erosion of 2.6%, and accretion of 1.45% indicate good inhibition, reducing wellbore instability, shale sloughing, tight hole, pack-off, and bit balling.

Abstract

Industri minyak dan gas bumi (migas) merupakan salah satu sektor strategis dalam perekonomian nasional maupun global. Dalam kegiatan produksi migas, khususnya pada fase hilir (downstream), terdapat berbagai aktivitas penting, salah satunya adalah proses pengangkutan dan penyimpanan kondensat. Penelitian ini menganalisis terjadinya losses atau selisih volume pada proses transfer kondensat dari tangki SNO-T-6001B ke tangki SNO-T-6010B di unit Central Plant Processing. Pengukuran dilakukan dengan metode tank Gauging pada tangki pengirim dan dibandingkan dengan volume aktual yang diterima tangki tujuan. Data diperoleh dari periode Februari hingga Oktober 2025. Hasil analisis menunjukkan bahwa rata-rata losses selama periode penelitian mencapai 38,39 bbl per kegiatan transfer. Faktor utama penyebab losses adalah perbedaan suhu antara tangki asal dan tangki penerima yang memengaruhi koefisien muai volumetrik kondensat, sehingga terjadi ekspansi atau penyusutan cairan yang berdampak pada perbedaan hasil pengukuran. Perhitungan kerugian finansial menunjukkan nilai rata-rata sebesar Rp.41.840.069. selama periode penelitian. Penelitian ini menyimpulkan bahwa kendali suhu tangki, kalibrasi alat ukur secara berkala, serta penggunaan koefisien muai kondensat yang lebih representatif diperlukan untuk meminimalkan losses dan meningkatkan keakuratan pengukuran transfer kondensat di fasilitas produksi.

Abstract

This study aims to analyze the impact of glycerol additives on the thermal stability of carrageenan biopolymers from Eucheuma cottonii at a salinity of 5000 ppm and a temperature of 60 °C, which serves as a simulation for Enhanced Oil Recovery (EOR) reservoirs. Carrageenan solutions were designed with varying glycerol concentrations, then tested for viscosity at room temperature and after heating using a viscometer. The results showed that the addition of glycerol had a significant effect on viscosity stability. The idea glycerol concentration was able to reduce the decrease in viscosity caused by heating, while too much glycerol actually reduced the effectiveness of the polymer due to its plasticizer effect. This study recommends the use of glycerol at an optimal concentration to improve the thermal stability of carrageenan as an environmentally friendly biopolymer alternative for EOR applications with a salinity level of 5000 ppm.
