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

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.

Abstract

Acid Mine Drainage (AMD) represents a critical environmental challenge in coal-mining regions, particularly due to its long-term impacts on surface water quality and surrounding ecosystems. This study investigates the lithological controls on AMD formation in the Sungai Seluang area, East Kalimantan, Indonesia, through an integrated rock characterization approach. The novelty of this research lies in linking detailed lithological attributes and pyrite micro-morphology with AMD generation potential and its implications for riverine water systems. Macroscopic lithological observations were combined with standardized pH testing (SNI 6989.11:2019) and Scanning Electron Microscopy (SEM) to evaluate the acid-generation characteristics of representative rock units. The results indicate that 92% of the analyzed samples are classified as Potentially Acid Forming (PAF), while only 8% are Non-Acid Forming (NAF). The study area is lithologically dominated by claystone (42%), sandstone (31%), and shale (27%), all of which commonly exhibit intense oxidative staining, pervasive fracturing, and weathering features that significantly enhance sulfide exposure to oxygen and water. SEM analyses reveal the presence of both euhedral and framboidal pyrite, with framboidal pyrite identified as particularly reactive and influential in accelerating acid production. Measured pH values are predominantly acidic (<6), indicating a high AMD potential that poses a serious threat to the Sungai Seluang system through acidification and metal mobilization. These findings demonstrate that lithology and micro-scale mineralogical characteristics play a decisive role in controlling AMD formation and its environmental consequences. The integrated approach adopted in this study provides a robust framework for early AMD source identification and supports the development of more effective geochemical management strategies aimed at protecting water quality and minimizing long-term environmental degradation in coal-mining areas.

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

This research aims to design a squeeze squeeze cementing job for well “RF-L” in field “D” using the balance plug method to isolate the MFS-8 formation layer, which has shown a decline in productivity and an increase in water production. The research method using the balance plug technique . The calculations were based on casing, tubing, perforation, and reservoir pressure data. The results indicate that the squeeze cementing operation requires 46 sacks of Class G cement with a total slurry  volume of 9.402 bbl and 5.5 bbl of mixing water. The volume of spacer ahead was 12.81 bbl and spacer behind was 1.09 bbl, while the displacement fluid volume was 4.5 bbl (after subtracting 1 bbl of underdisplacement). Reverse circulation of 5.2 bbl was performed to clean residual slurry  from the tubing. Hesitation and Waiting on Cement (WOC) were applied to ensure the cement hardened properly in the target zone without damaging the formation

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.
