Multi-zone completions in Tight Gas Reservoirs seriously challenge all conventional attempts to understand the zone-by-zone flow properties. Core calibrated log analysis identifies matrix reservoir properties and are the basic start to understanding reservoir properties. However, there are other flow mechanisms such as natural fractures that can have a major impact on the stimulation treatment design and flow potential.
In low permeability reservoirs, traditional buildup tests are just not cost effective often requiring over a month shut-in time to reach pseudoradial flow which is required to determine reservoir properties. Data Frac Injection Tests (DFIT) are one way to examine each zone in the well as it is being completed and assess the flow potential. DFIT tests often provide information that cannot be obtained by any other technique regarding the natural fracture contributions to fluid flow.
This presentation will examine case histories in detail to highlight the optimum design and analysis of DFIT tests
