About this document
Drawdown and Buildup Test Analysis by leong_guo is a document available to read on EtoBox.
This document summarizes different methods for analyzing drawdown, buildup, and variable rate well tests: - Drawdown tests can be analyzed by plotting pressure vs. log(time) which should form a straight line. The slope and intercept are used to determine permeability and skin factor. Non-linear behavior indicates boundaries. - Buildup tests use a Horner plot of pressure vs. (shut-in time+elapsed time)/elapsed time which also forms a straight line. The slope and intercept again yield permeability and skin
