Trican Corporate Director Reservoir Services, Robert Hawkes, will demonstrate why some of the well testing practices of the ‘80s and ‘90s are worth revisiting. He’ll examine these “trade secrets” and show how they can be easily used in today’s complex reservoirs for closure identification and after-closure analysis in shale plays.

Mr. Hawkes’ presentation will be held Tuesday, January 26, 2016 in the Eau Claire Room at the Westin hotel (320 4 Ave SW), 11:30 - 1 p.m. Lunch is provided.

Registration can be made through the SPE Calgary Events webpage


By definition, during Nolte Flow, pressure versus G-time has a constant slope and Nolte Flow is a sign of an open fracture. The departure from this constant slope is evidence of closure. Everyone would typically agree on this closure pick. Height Recession, Transverse Storage, Pressure Dependent Leak-off and Tip Extension, however appear, to be the more common signatures reported in well reports highlighting a) more complex reservoirs b) problematic data sets c) incorrect use of the G-function plot d) misunderstanding of the fluid leak-off dynamics, or all of the above.
