Flowing Material Balance (FMB) Analysis

The flowing material balance (FMB) analysis is a practical technique designed to estimate hydrocarbons-in-place from production rates and pressures. It uses precisely the same principles as a classical material balance analysis, but requires no shut-in data. This analysis method can be applied to all gas reservoirs (including dry or dewatered CBM reservoirs), and to oil reservoirs above the bubble point. It is designed for wells that have reached boundary-dominated flow, but can also be used to identify minimum original gas / oil in place (OGIP / OOIP) in transient cases.

Note:   The FMB analysis is available with an IHS RTA or IHS CBM license.

These items apply to the FMB analysis:

• Creating an FMB Analysis
• Analyzing a Group of Wells within a Single Reservoir
• Analyzing Reservoirs with Aquifer Support
• Including Pressure-Dependent Permeability / Rock Compressibility in the Analysis
• Accounting for Adsorbed Gas-in-Place for Shale Gas Plays
• Accounting for Changing Oil Properties
• FMB theory
