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

In oil and gas production, horizontal wells are increasingly used to enhance reservoir performance by placing a longer wellbore section within the reservoir. These wells often adopt specific inclinations either upward-sloping or downward-sloping terminal sections to align with formation dip and minimize issues such as liquid loading. However, undulating trajectories in horizontal wells may lead to challenges such as liquid accumulation in downward-sloping sections and gas entrapment in upward-sloping sections, potentially reducing production efficiency. This study aims to predict fluid production rates and analyze multiphase flow behavior in horizontal wells with varying wellbore inclinations using a production simulator. Four scenarios were modeled: Original, True Horizontal, Upward-Inclined End (95° and 100° inclination), and Downward-Inclined End (80° and 85° inclination). The study utilized 20 deviation survey data points from Well F-14 in Field ‘V’ to construct the well trajectory models, adhering to the simulator’s input limitations. Simulation results indicate that the upward-inclined configuration with a 100° inclination achieved the highest oil production rate (9401.8 STB/day), outperforming other scenarios in both oil and gas flow rates. The enhanced performance is attributed to gravitational assistance in fluid movement and reservoir pressure expansion. In contrast, the downward-inclined geometry yielded the lowest production due to higher liquid holdup. Gradient matching was employed to identify dominant flow patterns and slip velocities, revealing bubble flow dominance in horizontal sections and transition to slug flow in mid-well segments. These findings highlight the importance of well trajectory design in optimizing multiphase fluid flow and maximizing production in horizontal wells.

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.
