Abstract

The assessment of geothermal well production capability plays a crucial role in optimizing geothermal energy generation systems. This study focuses on evaluating the performance of two geothermal wells, ZM-42 and ZM-31, located in the AAP Field, by developing output curves through wellbore simulation techniques. The analysis utilizes field production test results, well casing configuration data, and PTS (Pressure, Temperature, and Spinner) survey data to generate key parameters such as wellhead pressure, fluid flow rate, fluid temperature, enthalpy, and vapor fraction (dryness). These parameters are essential for understanding the thermal and flow characteristics of each well. Wellbore simulations were conducted using specialized software to replicate the flow behaviour of geothermal fluids within the well system. The output curves produced provide a graphical representation of the relationship between wellhead pressure and mass flow rate under various operating conditions. Validation of the simulation was done by comparing the generated curves with actual field measurements. The results show that well ZM-31 demonstrates a higher production capability compared to ZM-42. ZM-31 recorded a flow rate of 96.61 kg/s and an enthalpy of 1134.5 kJ/kg, with a vapor fraction of 0.14. In contrast, ZM-42 exhibited a lower flow rate of 85.60 kg/s, enthalpy of 1027.7 kJ/kg, and a vapor fraction of 0.11. These differences indicate superior separation efficiency and thermal performance in ZM-31. Furthermore, ZM-31’s production is dominated by a single feed zone, while ZM-42 relies on multiple contributing zones. In conclusion, based on output curve analysis and well simulation results, ZM-31 is recommended as the primary production well for further optimization in the AAP geothermal field, contributing to more efficient and reliable energy output.

Abstract

Water-based drilling fluids commonly exhibit rheological degradation under high-temperature, high-pressure (HTHP) conditions, resulting in significant reductions in viscosity, yield point (YP), and gel strength (GS). Previous studies relying on conventional additives such as PAC, CMC, KOH, and NaOH have not fully resolved this issue, particularly in maintaining rheological stability at elevated temperatures. This study addresses this gap by introducing an alkaline polymer as a multifunctional additive intended to replace several conventional components while enhancing thermal resistance. Response Surface Methodology (RSM) with a Box–Behnken design was used to evaluate the combined effects of Carboxymethyl Cellulose (CMC) and alkaline polymer at three temperature levels: 80°F, 150°F, and 250°F. Experimental results show that at 150°F, the optimized formulation consists of 3.5 g CMC and 3.6 g alkaline polymer, yielding a viscosity of 17.64 cP, plastic viscosity of 12.46 cP, and a YP of 7.72 lb/100 ft², representing a substantial improvement compared to the baseline formulations, where YP values decreased significantly with temperature. The optimized mud also demonstrated improved gel strength and consistent filtrate control relative to non-optimized systems. The novelty of this study lies in the use of an alkaline polymer as a single multifunctional substitute for multiple drilling-fluid additives, combined with a multi-temperature RSM optimization framework. The findings provide a simplified, thermally stable drilling-fluid formulation suitable for HTHP environments.

Abstract

One physical characteristic that is helpful in comprehending the physical and chemical characteristics of a solution is the density of the polymer solution. Its primary function is to ascertain the polymer's concentration in solution. The density value can be used to estimate the polymer concentration in solution. The study of the flow and viscosity of polymer solutions also makes use of the interaction between the polymer and solvent. This study aims to establish a relationship between the density of porang and xanthan gum solutions and the percentage of porang, polymer content, and salinity. Machine learning models, like the Adaptive Neuro Fuzzy Inference System (ANFIS) and Artificial Neural Network (ANN), are used for modeling. The creation of these machine learning models used 471 digitized data of density curves of porang solution, xanthan gum solution, and porang-xanthan gum mixture solution. The training, validation, and testing processes of the ANN and ANFIS models provided average correlation coefficients of 0.99955 and 0.99999, respectively. Comparison between the estimates of the ANN and ANFIS models and the measurement results of 27 porang and xanthan gum solutions provided accurate results with correlation coefficients of 0.99893 and 0.99996, respectively.

Abstract

The upstream oil and gas industry is under global pressure to reduce carbon emissions while maintaining production levels. One of the key technologies projected to play a vital role in this energy transition is Carbon Capture and Storage (CCS). This technology captures carbon dioxide (CO₂) emissions from industrial activities and stores them in underground geological formations, including depleted oil and gas reservoirs. Indonesia, as an oil-producing G20 member, has a significant opportunity to develop CCS due to the availability of geological formations suitable for carbon storage. This study aims to identify the potential, challenges, and implementation strategies of CCS in Indonesia’s upstream oil and gas sector through a literature review and conceptual analysis approach. The findings indicate that CCS implementation could support Indonesia’s Net Zero Emission 2060 target, although challenges remain in terms of financing, regulatory framework, and technological readiness. Strategic efforts such as policy strengthening, cross-sector collaboration, and human capital development are essential to accelerate CCS deployment.

Abstract

Indonesia’s persistent dependence on imported diesel fuel poses significant challenges to national energy security, fiscal stability, and exposure to global market volatility. In response, the government plans to implement a mandatory B50 biodiesel blending policy starting in 2026 to reduce diesel imports by leveraging domestic bioenergy resources. While higher blending mandates are often assumed to directly lower imports, existing studies largely rely on static or deterministic approaches that inadequately capture feedback dynamics and long-term uncertainty. This study addresses this gap by integrating system dynamics modelling with Monte Carlo simulation to analyze the impact of biodiesel blending policies on diesel import dependency under structural and parametric uncertainty. The model incorporates biodiesel production growth, domestic allocation after exports, diesel demand growth, and blending effectiveness within a feedback-based framework calibrated using historical data from 2013 to 2024. Simulation results indicate that the B50 policy consistently reduces diesel import requirements relative to the baseline; however, absolute imports may continue to rise without sufficient domestic supply expansion. Cumulative results show that by 2035, the B50 policy achieves import reductions of approximately 55–58 million kiloliters, increasing to around 60 million kiloliters when combined with accelerated biodiesel production growth. Monte Carlo analysis reveals robust medium-term outcomes by 2030 but increasing uncertainty by 2035. The findings highlight that blending mandates must be accompanied by sustained supply-side development to ensure long-term effectiveness and resilience.
