Abstract

The demand for fossil fuels continue to increase, this encourages the production of hydrocarbons to be increased as well. Enhanced Oil Recovery is one option that can be considered to overcome this high demand. Technical complexity and sophisticated technology are commonly used in EOR implementation. This has become one of the obstacles to implement EOR, one of which is the requirement relatively large funding. Microbial Enhanced Oil Recovery is one method that can be considered as a technology that can fulfill commercial production gains and the resulting environmental impact is lower than other EOR methods. MEOR uses micro-organisms whose metabolism results can change the physical properties in the reservoir so that oil production can be increased.

Abstract

Lumpur Pemboran merupakan salah satu sarana yang penting dalam operasi pemboransumur-sumur minyak dan gas bumi. Pada proses pemboran berlangsung biasanya terdapat berbagai kendala, salah satunya adalah terjadinya Lost Circulation. Lost Circulation adalah hilangnya sebagian atau seluruh fluida pemboran saat sirkulasi sedang berlangsung. Lost circulation terjadi karena rekahan pada dinding pemboran baik rekahan yang terjadi secara alami atau secondary. LCM (Lost Circulation Material) adalah suatu metode yang digunakan untuk menanggulangi Lost Circulation dengan menambahkan sejumlah material pemberat kedalam lumpur pemboran ataupun dengan cara memompakan sejumlah material pemberat kedalam formasi lost. LCM yang digunakan pada penelitian ini adalah Fracseal dan CaCO3. Cara Kerja dari CaCO3 dan Fracseal ini terhadap lost circulation adalah dengan cara menutup pori pori atau zona rekahan formasi sehingga fluida tidak masuk kedalam formasi. Pada penelitian ini, pengaruh LCM terhadap filtrat lumpur pemboran mengalami penurunan jumlah filtrat yang hilang, pada pengujian 3% LCM mengalami penurunan filtrat dari 7 ml/ 30 menit menjadi 5 ml/ 30 menit, dan untuk 5% LCM mengalami penurunan menjadi 4,6 ml/ 30 menit.

Abstract

One phenomenon that can occur when a polymer solution is injected into an oil reservoir is adsorption. Adsorption occurs due to interactions between polymer molecules and the reservoir pore surface. Adsorption causes some polymer molecules to be removed from solution. So, this process results in a reduction in the polymer concentration in the solution. In this study, an artificial neural network (ANN) model is used to estimate the adsorption of shrimp chitosan polymer on the surface of 40 mesh and 60 mesh sand grains. The ANN model can estimate adsorption more accurately than previous models. This is because previous models only predicted certain adsorption patterns, while the ANN model is able to predict adsorption with complex relationships. The comparison of the mean absolute relative errors (MAREs) of the ANN, Langmuir, Freundlich, Henry, and Harkins-Jura models is 5.7%, 15.9%, 14.6%, 15.2%, and 14.5%, respectively.

Abstract

The amount of shrimp shell waste is quite abundant in Indonesia, but its utilization is not optimal. Shrimp shells contain chitin that can be processed into chitosan. Chitosan polymer can be developed for Enhanced Oil Recovery. Testing the characteristics of shrimp shell chitosan has been carried out, but the recovery factor results in coreflooding are still very small. Additional characteristic tests such as adsorption tests are needed. This study was conducted to determine the characteristics of shrimp shell chitosan polymers by conducting tests such as compatibility tests, viscosity, adsorption. In this study, an experiment was conducted using biopolymer-chitosan with shrimp shell raw materials. The material for making formation water used NaCl with a salinity of 10,000 and 20,000 mg/L. The concentration of chitosan biopolymer was varied with 5,000, 10,000, and 15,000 mg/L. The size of the sand grains used was 60 mesh. The results of the tests that had been carried out all samples were declared compatible for use. The highest viscosity value was 1,055.19 cP and adsorption was 26.63 mg/g.

Abstract

Drilling mud filtration plays an important role in maintaining wellbore stability and preventing excessive fluid loss during the drilling process. If uncontrolled, filtration can damage formations and disrupt operations. This study discusses the effectiveness of High-Pressure Water-Based Mud (HPWBM) with the addition of CaCo3 and Fracseal as an effort to reduce filtration and form a good mud cake. The purpose of this study is to evaluate the filtration performance of HPWBM in various well sizes under HighPressure High-Temperature (HPHT) conditions. This test was conducted in accordance with API standards ( 10 ml/30 minutes). The results show that the filtration rate for the 26“ trajectory is 4.6 ml/30 minutes, the 17-1/2” trajectory is 3.8 ml/30 minutes, the 12-1/4“ trajectory is 4.0 ml/30 minutes, and the 8-1/2” trajectory is 2.4 ml/30 minutes. All values were below the API limit, with a decreasing trend at greater depths. This study confirms that HOWBM with CaCo3 and Fracseal can control filtration, maintain well stability, and improve drilling efficiency and safety.

Abstract

This systematic literature review discusses the optimisation of steam flooding as one of the important enhanced oil recovery (EOR) methods for heavy oil production. Steam flooding is proven to reduce oil viscosity, increase fluid mobility, and improve sweep efficiency. However, the main challenges include high steam-oil ratio (SOR), large energy requirements, reservoir heterogeneity, and operational costs. Through a Systematic Literature Review (SLR) of 5 selected journals published in 2023-2025, this study identifies optimisation strategies such as injection pattern design, steam quality control, use of supporting technologies such as horizontal wells and solvent injection, and renewable energy integration. The results show that technical optimisation includes injection pattern design, steam rate and quality control, well configuration (including the use of horizontal wells), and remedial stimulation through acidising. On the economic side, the focus was on reducing Capex and Opex, increasing Net Present Value (NPV) and Internal Rate of Return (IRR), and oil price sensitivity. In addition, innovation in the form of Solar Enhanced Oil Recovery (S-EOR) offers a sustainable solution in reducing energy costs and reducing carbon emissions.

Abstract

Drilling mud is a crucial element factor in the drilling process, serving to clean cuttings also resolve downhole issues. High-Performance Water-Based Mud (HPWBM) is a significant advancement, utilizing polyamine to inhibit water absorption in shale and clay formations while offering ecological and economic benefits. A major challenge in drilling is lost circulation, where mud flows into formation gaps due to pressure differentials or formation characteristics. This study focuses on an HPWBM innovation using Calcium Carbonate CaCO3 and Fracseal as Lost Circulation Materials (LCM) to treat total lost circulation. CaCO3 and Fracseal act as effective plugging agents for fractures and pores. The objective is to analyze the performance of this system by evaluating the changes in rheological properties and the effectiveness of Fracseal dosages across different well sections, specifically the 17-1/2", 12-1/4", and 8-1/2" holes. The results demonstrate that this innovative mud system effectively restores wellbore stability and prevents severe mud loss, offering a viable solution that enhances safety, efficiency, and provides potential cost savings in oil and gas drilling operations.

Abstract

Enhanced Oil Recovery (EOR) merupakan metode penting untuk meningkatkan perolehan minyak, khususnya seiring dengan tuntutan praktik industri migas yang berkelanjutan. Penelitian ini bertujuan mengkarakterisasi kinerja kitosan dari limbah kulit udang sebagai biopolimer ramah lingkungan untuk aplikasi EOR, dengan fokus pada stabilitas dalam air formasi bersalinitas tinggi dan karakteristik adsorpsinya pada media batuan. Metode yang digunakan meliputi uji kompatibilitas visual dan uji adsorpsi sistem batch, di mana larutan kitosan dengan variasi konsentrasi (5.000–15.000 mg/L) diuji pada salinitas 10.000 dan 20.000 mg/L NaCl menggunakan pasir silika 40 mesh sebagai media berpori. Konsentrasi larutan dianalisis menggunakan spektrofotometer UV-Vis. Hasil penelitian menunjukkan larutan kitosan stabil secara visual tanpa membentuk endapan pada seluruh variasi konsentrasi dan salinitas. Nilai adsorpsi meningkat seiring kenaikan konsentrasi dan salinitas, dengan maksimum 14,13 mg/g pada salinitas 20.000 mg/L, yang disebabkan oleh interaksi elektrostatik dan efek charge screening. Temuan ini mengindikasikan bahwa kitosan berpotensi besar sebagai biopolimer EOR yang efektif dan berkelanjutan, dengan stabilitas tinggi pada kondisi salinitas serta sifat adsorpsi yang mendukung peningkatan efisiensi penyapuan minyak.

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.
