There are 5 basic techniques which can be used to analyze transient pressure data from hydraulically fractured wells: modified pseudo-radial flow (semi-log analysis), formation linear flow (square-root time analysis), bilinear flow (fourth-root time analysis), type curve analysis, and reservoir simulation history matching analysis. These techniques are applied to evaluate formation matrix permeability, created fracture half length, and fracture conductivity. Each technique has its advantages and disadvantages in estimating the above-mentioned parameters. Examples of transient pressure analysis for hydraulically fractured wells in the Western Tight Sands area have been used to demonstrate how the different techniques can provide a range of values for the above parameters. A representative example shows the matrix permeability calculations to range between 0.02 and 0.051 md as compared to the design parameter of 0.025 md. The fracture half length and conductivity estimates varied between 242 to to 1,425 ft and 56 to 253 md-ft compared to the design parameter of 500 ft and 200 md-ft, respectively. 35 references.
