Performance Evalu​ation of Refractured Wells



Well refracing has become a game changer in the oil industry. However proper planning, selection of candidate wells, and prediction of refrac results is essential. This course deals with how to evaluate the expected performance of refracing and the comparison of other option such as infill drilling using various up-to-date analytical and numerical software.


This course is aimed at all the technical staff such as reservoir, petroleum and exploitation engineers/technologists, geophysicists, who are involved in hydraulic facing
