Mapping Research Trends in Oil Supply Chain Optimization: A Bibliometric Analysis

The oil industry operates in an increasingly competitive environment, making efficiencyimprovements across operational processes essential particularly in transportation logistics. The oilsupply chain is typically divided into three stages: upstream logistics, which ensures extractionfacilities have the necessary materials and equipment; midstream logistics, involvingtransportation, storage, and processing; and downstream logistics, which delivers refined productsto customers. A preliminary bibliometric review using the Publish or Perish software and Scopusdatabase highlights the limited attention given to oil supply chain optimization, with only 78relevant publications from 2014 to the present, most of which are concentrated in mining scienceand engineering rather than logistics-focused studies. To bridge this gap, this study applies thePRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) framework,integrating quantitative and qualitative approaches, combined with VOSviewer software for mapping and visualization of research trends. Results reveal that the keywords “optimization” and“production” have a relatively weak connection with the oil and gas supply chain literature,suggesting underdeveloped research linkages. Additionally, mathematical-based optimizationmethods dominate the existing body of work, while alternative approaches remain underexplored.This imbalance indicates the need for broader investigations that not only focus on individualstreams of the oil supply chain but also incorporate diverse optimization techniques beyondmathematical modeling. By doing so, future research can generate more comprehensive insights,support the design of more resilient and efficient supply chains, and provide practical contributionsto an industry that continues to face pressures of competition, energy transition, and global marketvolatility.
