Abstract

The implementation of Indonesia’s Zero Oil Hydrocarbon (TPH) regulation for offshore drilling waste disposal by 2025 presents significant operational and technological challenges for oil and gas companies. This study aims to evaluate and prioritize strategic alternatives that support compliance with the 0% TPH requirement while maintaining operational efficiency and cost-effectiveness. Using a mixed methods approach, this study integrates thematic analysis of stakeholder interviews with quantitative assessment using the Analytical Hierarchy Process (AHP). Five key criteria – environmental compliance, operational efficiency, cost-effectiveness, technology readiness, and regulatory risk mitigation – are used to evaluate four strategic alternatives. Expert judgments from Medco Energi and SKK Migas are synthesized to develop a decision hierarchy. The results indicate that onshore treatment and disposal (30.73%) is the most preferred option, followed by third-party waste management services (26.15%), offshore reinjection (24.49%), and thermal desorption units (18.64%). The implications of this study are that qualified experts in environmental management, offshore drilling, and waste treatment provide input to the AHP model to ensure a robust and multidimensional evaluation. The novelty of this research demonstrates strategies that emphasize infrastructure optimization, stakeholder collaboration, and ESG-based innovation to support regulatory compliance and sustainability in offshore drilling waste management

Abstract

PetroComp, a private oil and gas operator in Eastern Indonesia, has a limited room for gas production growth. A potential new long-term gas sales agreement (GSA) with PT. SMC, could double PetroComp’s gas production and address its long-term growth needs. Jala field is the potential undeveloped resource to fulfill the gas demand requirement, however it contains high CO2 concentration which presents substantial investments for its development. Three development scenarios of Jala field are evaluated in the study, including a potential integration of CCUS.This study aims to evaluate the economic feasibility of the three development scenarios of Jala sour gas field using a Discounted Cash Flow (DCF) method to determine the best development strategy for PetroComp and Government of Indonesia. Conventional onshore development approach provides the highest NPV at US$ 113.8 million, meanwhile CCUS and full offshore development scenarios are not economic due to its high investment cost. Gas production volume and gas price are the most sensitive parameters affecting the project’s profitability based on the sensitivity analysis. Uncertainty analysis suggests a promising thick positive NPV is expected from the project with the P90-P50-P10 cases are ranging from US$ 50.8 – 173.9 million. Time-dependent evaluation concludes the impact on profitability start to de-escalate exponentially if the project is delayed for more than four years (>10% NPV impact) at the given PSC period until 2045. This study is intended to support evidence-based decision-making by PetroComp in developing the high-CO2 Jala gas field and advancing the company’s long-term growth strategy.

Abstract

The study evaluates the robustness of a gas settlement method using the Analytical Hierarchy Process (AHP) to systematically prioritize multiple variables in complex multi-seller, multi-product, and multi-buyer conditions, affected by technical, contractual, and regulatory factors. Expert interviews identified critical variables such as inlet volume, Gross Heating Value (GHV), and operational dynamics across upstream, midstream, and downstream process. AHP calculations and Consistency Ratios validated expert judgments, deriving priority weights for each criterion and subcriterion. Testing scenarios revealed gaps in the lowest scoring scenario, leading to a proposed business solution for dynamic monitoring and integration of system disruptions into the settlement model. The study concludes that AHP-based methodologies provide a structured, transparent decision-making framework suited for complex, multi-stakeholder environments in the East Kalimantan System, advocating for continuous improvement and monitoring to maintain alignment with operational conditions.

Abstract

Oil (crude) refineries are a fundamental infrastructure of the primary energy in the world. Fuel oil and its derivative products are important commodities needed by society and industry and have always been a concern for every government in the world because of its strategic values (economic, political, and security factors). In Indonesia, the oil and gas industry play a very important role for the nation. In the early days of independence, crude oil was the prima donna of exports commodities and as the foundation of development in Indonesia. But over time, when massive development took place and Indonesia's economy continued to grow into a developing country followed by population growth, this sector was in the spotlight because it was the culprit for contributing to Indonesia's massive import value. Various efforts were made by the Indonesian government to realize energy self-sufficiency so as not to depend entirely on imports, for example through Pertamina as a state-owned enterprise to build the Balongan Refinery. The Balongan refinery was designed and built using the most advanced technology and configurations at the time so that it could process low-cost heavy/very heavy crude oil into a variety of fuels, petrochemicals, and other products. Despite having a highly advanced configuration (11.9 NCI) that far exceeds other domestic refineries as well as refineries in Asia, the Balongan Refinery is under economic pressure from various external factors, such as rising crude oil prices and the preference for higher-priced product types by the market. This research seeks to address and formulate the strategies for the Balongan Refinery to improve its operating performance and economics. The important aspects of the strategy that were researched and evaluated, which were then proposed as the main findings in this study, were the strategy of utilizing potential crude oil alternatives and the strategy of diversifying superior products referring to product price trends in the market. This study also found that flexibility in the selection and processing of potential crude oil by means of an adaptive approach to the actual conditions faced, do not just be strict with design figures, at attractive prices is the key to ensuring the operational and business sustainability of the Balongan Refinery.
