The lecturer at the College of Oil Engineering at Al-Ayen University Dr. Diyaa Khafeef has published his scientific research entitled: ((Performance evaluation of analytical methods in linear flow data of hydraulically-fractured gas))in the journal of Petroleum science and engineering which is classified under global capacity and one of the Elsvier: Q1 journals of impact factor: 4.346.
Through this study the appropriateness and accuracy, of the different analytical and mathematical methods used to measure the length of the hydraulic fractures at the wells of non- tradition gas field, were researched. diagnoses tools were discovered which determine when and where some of these mathematical methods can be used and when they give inaccurate results
