2-Day Open DFIT/Fracture Pressure Analysis Course - Led by Dr. J.Y.Deng

$2350/USD

Led by Dr. Jiayao (J.Y.) Deng

The course is presented in a “workshop” fashion. After a brief review of frac­turing pressure analysis background, basic closure pressure analysis techniques, etc., we also discuss “non-ideal” cases. These are then reviewed by working through actual case history data. This includes natural fracture (pressure dependent) loss, horizontal well DFIT, After-Closure-Analysis (ACA) type curves for detecting stress sensitive permeability, etc. Time is also set aside to review cases/data brought by the participants – everyone is urged to bring their own data for review by the group. A planned agenda is included below, but this often changes during the course.
