Type Curve Analysis 2 Upon completion of this section, the student should be able to: 1. Identify wellbore storage and middle time regions on type curve. 2. Identify pressure response for a well with high, zero, or negative skin. 3. Calculate the equivalent time for use in analyzing pressure buildup tests using drawdown type curves. 4. Calculate wellbore storage coefficient, permeability, and skin factor from type curve match.

Type Curve Analysis 6 The Gringarten type curve describes the pressure response under the following assumptions: 1. Constant rate production from a 2. Vertical wellbore in an 3. Infinite-acting homogeneous reservoir that is 4. Filled with single phase liquid of small and constant compressibility 5. Infinitesimal skin that may be modeled with an apparent wellbore radius 6. Constant wellbore storage coefficient The Gringarten type curve was specifically developed for drawdown tests in oil wells. We will see that we may use it
