Abstract
In this chapter, practical approaches for analyzing well performance in shale gas reservoirs are presented. Mini-frac test are performed before main fracturing to determine the reservoir and fracture properties for the main stimulation design. It is generally performed without proppant and the basic principles are analogous to those for pressure analysis of transient fluid flow in the reservoir. Decline curve analysis (DCA), which is used to forecast future production in the conventional reservoirs, can be also used to forecast future production in the shale gas reservoirs. In conventional reservoirs, engineers have used an empirical analysis method, .i.e. exponential and hyperbolic relations, introduced to the industry for evaluating estimated ultimate recovery (EUR).
