Benoit Technical Tools: Voidage Replacement Ratio
Reservoir Management
Jun 26, 2026
Benoit Regulatory's Voidage Replacement Ratio tool helps operators calculate, monitor, and communicate VRR performance by pattern or pool.
Voidage replacement ratio is an important reservoir-management measure for waterfloods and other injection-supported recovery schemes. Operators need to understand how produced reservoir volumes compare with injected volumes and whether injection is keeping pace with production. Tracking VRR over time can help identify trends, evaluate injection effectiveness, and support decisions related to pressure maintenance and scheme performance.
The VRR tool is designed to simplify this analysis by organizing production and injection data into practical outputs that can be reviewed over time. It supports monthly and cumulative VRR evaluation and can help operators communicate reservoir-management performance in a consistent format.
This tool is part of the Benoit Technical Toolkit, a suite of web-based tools built to support practical regulatory and technical workflows for oil and gas operators. The Toolkit is intended to reduce spreadsheet complexity, improve consistency, and make technical analysis easier to document and review.
Benoit Regulatory can also support operators with waterflood performance reviews, reservoir-management reporting, injection scheme support, Directive 065 applications, and related regulatory compliance requirements.
