Abstract: This paper gives following results.(1) A method is presented to deter-mine total pressure transmissibitity θby pressure build-up data from a well.Its advantage is that only pressure build-up data are required without pressure drawdown testing data,(2) A mehtod is presented to determine cross flow coefficient λ from pressuredrawdown data;(3) Two methods are presented to determine the crossflow coefficient λfrom pressure build-up data.Their advantages are that only data of build-upwell testing is required without pressure drawdown testing data.Thus they are better than the methods now in use.practical examples are given to demonstrate these methods.
