This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 175004, “The Reservoir-Technical-Limits Approach Applied To Maximizing Recovery From Volumetric and Aquifer-Drive Gas Fields,” by Abdelmadjid Alane, Peter J. Lumsden, P. Craig Smalley, Richard Hallam, Peter A. Salino, SPE, Steven J. Wells, and Tim J. Primmer, BP, prepared for the 2015 SPE Annual Technical Conference and Exhibition, Houston, 28–30 September. The paper has not been peer reviewed.
Maximizing recovery of hydrocarbons from oil and gas fields represents responsible asset management and is extremely valuable to both the operator and the host country. Successful pursuit of this goal involves a complex combination of technical, commercial, organizational, and human factors. This paper describes recent progress in developing a proprietary recovery-factor-evaluation process.
In 2002, a root-cause analysis was carried out on the basis of both externally published and internally held data to identify key success factors for increasing recovery factor in both gas and oil fields. This root-cause analysis led to the development of a robust and systematic approach to identify and describe opportunities called the Reservoir Technical Limits (RTL) system. Since its first application, this process has provided a systematic framework to identify new recovery-improving activities across a portfolio of fields, generate clear ownership of the activities by field teams and individuals, and identify technology requirements (existing or new) to progress the opportunities. This process has proved highly effective in identifying and evaluating the practical recovery potential within these fields.
The process hinges on breaking the overall recovery factor into separate-component efficiency factors so that targeted recovery-enhancing methods can be evaluated.
The system is used to evaluate the life-of- field recovery potential of oil and gas fields, and the steps required to achieve this potential, on the basis of the following key factors:
- Depth of technical knowledge across multiple functions
- Innovation, creativity, and awareness of latest technologies
- Understanding field specificity, so that identified opportunities are properly applicable to the field under review
