Analysis Analysis of Energy Consumption Performance in Oil and Gas Utility Systems Using Baseline and Specific Energy Consumption (SEC) Approaches

Abstract

Abstract

This study examines the performance of energy consumption in utility systems within Indonesia’s oil and gas industry by employing a baseline model and the Specific Energy Consumption (SEC) indicator. Using national secondary data, the research develops an operational energy profile, evaluates the relationship between production levels and energy demand through linear regression, and assesses potential energy savings under various conservation scenarios. The analysis shows that monthly energy consumption remained within 305,000–321,000 kWh, reflecting the continuous nature of oil and gas operations. SEC values ranged from 28.0 to 28.4 kWh/BOE, indicating relatively consistent energy intensity. The baseline model produced a slope of 29.504 kWh/BOE and an R² of 0.94, confirming a strong correlation between production and energy use. Two conservation scenarios demonstrated annual savings of 179,109 kWh (moderate) and 554,419 kWh (aggressive). These findings demonstrate that baseline and SEC analyses serve as effective engineering tools for identifying inefficiencies and supporting energy optimization efforts in oil and gas facilities.
