Abstract

This study interprets biomarker characteristics and evaluates the genetic relationship between oil samples and potential source rocks from the TNG-1 well in the Cekungan Sumatra Tengah. The analysis was conducted using oil and rock geochemical parameters, n-alkane chromatograms, terpene and sterane distributions, as well as sterane ternary plots (C₂₇–C₂₈–C₂₉). The results indicate that oil samples at intervals of 5238–5277 ft, 5246–5248 ft, and 5266–5268 ft exhibit consistent geochemical characteristics and suggest thermal maturity within the early to mid-mature oil window. In contrast, rock samples at intervals of 4814 ft, 5046 ft, and 5151 ft show immature characteristics, indicated by CPI > 1.0, high Pr/nC₁₇ ratios, and n-alkane distributions biased toward long-chain compounds. Biomarker analysis reveals similarities in n-alkane distribution patterns, isoprenoid ratios, and C₂₇–C₂₈–C₂₉ sterane compositions between oil and source rock samples, indicating a strong genetic relationship. Sterane compositional correlation suggests that most samples, both oil and rock, originated from shallow lacustrine to estuarine depositional environments with significant higher-plant input. Overall, the oil samples show a strong correlation with the source rock at the 5151 ft interval based on the consistency of n-alkane, hopane, and sterane patterns.

Abstract

The oil and gas sector is one of the main pillars of the national economy and is currently facing the challenge of declining production, making the enhancement of human resource (HR) quality in the upstream oil and gas industry a strategic necessity. The core problem lies in the absence of optimal synergy between the oil and gas industry and the education sector, as reflected in the mismatch between higher education graduates’ competencies and industry needs, including in the South Sumatra Region (Sumatera Bagian Selatan, Sumbagsel), which comprises South Sumatra, Jambi, Bengkulu, and Bangka Belitung Provinces. This study aims to describe the establishment and role of Migas Center UNSRI as a form of community service in improving oil and gas HR competencies in the Sumbagsel region through collaboration between Universitas Sriwijaya and SKK Migas Sumbagsel. A descriptive qualitative approach was employed to examine the implementation of community empowerment policies and the mapping of upstream oil and gas industry needs at the regional level. The findings show that the collaboration between Universitas Sriwijaya and SKK Migas Sumbagsel resulted in an agreement to establish Migas Center UNSRI as a center for research and training in oil and gas management in South Sumatra. The existence of Migas Center provides the education sector with a clearer picture of industry requirements, including the importance of establishing study centers and certification bodies located in Sumbagsel so that companies do not have to rely on facilities in Java. Conceptually, Migas Center UNSRI is positioned as the forerunner of the establishment of a Petroleum Engineering Department at Universitas Sriwijaya as well as an instrument for strengthening the capacity of local human resources in the oil and gas sector.
