Summary:
The problems of planning of well tests by the methods of pressure build-up or drawdown curves registration are considered in the article.The existing approaches to the estimation of the time of the radial filtration start are analyzed. Based on the results of modeling and analysis of actual examples of the studies, a criterion of achieving the start time of the radial fi ltration depending on the productivity for horizontal and fractured wells was obtained.Examples of using the obtained relationships to assess the reliability of PBU interpretation parameters are presented
