Abstract

PT Pertamina Hulu Mahakam (PHM) is an oil and gas exploration and production operator in the Mahakam block, East Kalimantan, and conducts drilling operations for development and exploration wells using five offshore rigs. Mudlogging services are crucial for real-time geological monitoring and operational safety in offshore drilling. Mudlogging plays a crucial role in maintaining well integrity and enhancing drilling efficiency. From 2019, these services have been delivered through two major contracts, one awarded to PTGI and the other to a consortium between PTEN and PTGS. However, the second period (2022-2024) saw a sharp decline in performance, resulting in an estimated USD 350,000 in rig standby costs. This research aims to identify the root causes of the decline in mudlogging performance and propose practical improvement strategies to restore operational reliability and minimize non-productive time (NPT). A mixed-method approach was adopted, combining structured interviews with key stakeholders, and Likert-scale questionnaires were collected from the stakeholders and expert. Qualitative data analysis, utilizing root cause methodologies, fishbone diagrams, and current reality trees (CRTs), revealed that the absence of clear governance structures and role clarity led to weak coordination, delayed decisions, ineffective communication, and inadequate technical oversight. Insufficient training, high turnover, and limited motivation among contracted personnel in one of the consortium company were also identified as contributing factors in this research. The analytic hierarchy process (AHP) was applied to prioritize improvement strategies, with restructuring the consortium scoring highest and training enhancement being the most impactful levers for restoring performance.

Abstract

The persistence of manual weighing practices in coal transportation has led to significant revenue losses at PT Borneo Indobara, with a recorded discrepancy of -1.218% in coal tonnage reconciliation during Q4 2023—exceeding the company’s ±0.5% threshold. This research aims to identify the root cause of this issue, evaluate alternative solutions, and propose a strategic implementation plan to eliminate manual weighing. Employing the Current Reality Tree (CRT) method, the study found that the core issue was the absence of prior investigation into weighing alternatives. Using both primary (interviews, FGDs, observations) and secondary data (company reports, standards), three alternatives—Weighbridge, Low-Speed Weigh-in-Motion (LS-WIM), and High-Speed Weigh-in-Motion (HS-WIM)—were assessed using the Analytic Hierarchy Process (AHP) based on accuracy, productivity, and investment cost. The LS-WIM alternative emerged as the most optimal, scoring 0.37, due to its high productivity and moderate cost, despite slightly lower accuracy. Implementation is planned through a structured PDCA-based approach, covering proposal development, tendering, construction, and commissioning. With LS-WIM's expected accuracy of ±2%, the study projects a reversal of revenue loss into a gain of approximately USD 314,963.27, illustrating the business value of replacing manual weighing. This research contributes a novel integration of CRT and AHP methodologies in the coal logistics context and provides an actionable, stakeholder-informed roadmap for technology implementation. Future studies are encouraged to explore long-term performance, hybrid system integration, and cross-industry applicability of weigh-in-motion technologies.
