Single-Well Benefit Classification in Oil and Gas Reservoirs: Current Insights and Future Prospects

Against the backdrop of continuously growing global energy demand and increasingly tight oil and gas resources, single-well economic benefit evaluation has become a crucial tool for optimizing resource allocation and enhancing development efficiency. This paper reviews recent research progress in single-well benefit evaluation within oil and gas fields, covering benefit evaluation metrics, benefit classification standards, benefit-based production allocation, and single-well economic thresholds. It analyzes the achievements and shortcomings of existing research and outlines future research directions.
