| Abstract: | A theoretical development is presented in this paper which provides a concise and accurate method of handing the drawdown analysis for variablerate case. In this mothod the curves of production variation are replaced by broken-lines istead of a steped lines. Eq (6) is deduced to analyse pressure drawdown performance, the X in Eq (6) is given by Eq (7), (14) and/or Eq (19) for one, two and/or three line-segments respectively. |
