Is well classification determined solely by gas-oil ratio (GOR)?

Can a gas well produce oil and still remain classified as a gas well?

Can historical well classifications be evaluated using today's rules?

What is one of the most common misconceptions about well classification?

Benoit Technical Tools: Declines, Volumetrics and Material Balance

Reservoir Management

Jun 26, 2026

Benoit Regulatory's Declines, Volumetrics and Material Balance tool is designed to help operators evaluate reservoir performance using practical forecasting and reserves-analysis workflows.

Decline analysis, volumetric estimates, and material balance reviews are commonly used to understand production behaviour, estimate recoverable volumes, and support reservoir-management decisions. These workflows can also help operators communicate technical assumptions and review development opportunities, performance trends, and recovery expectations.

The tool allows users to work with production and pressure data, evaluate decline behaviour, estimate reserves, and connect analysis results to broader reservoir-performance interpretation. The objective is to provide a practical web-based workflow that supports clear technical outputs without requiring a full enterprise software environment.

This tool is part of the Benoit Technical Toolkit, a collection of web-based applications created for oil and gas operators who need practical engineering and regulatory tools. The Toolkit supports common workflows related to H2S release-rate adjustments, pressure-loss analysis, VRR monitoring, decline analysis, volumetrics, and material balance.

Benoit Regulatory can also assist with reservoir-performance reviews, reserves support, waterflood evaluation, material balance interpretation, and regulatory submissions where supporting technical analysis is required.
