Flowback Analysis (FBA)

Fracture Property Evaluation from Flowback and Early-Time Production Data

Flowback Analysis – Prepared and presented by SPE Distinguished Lecturer C. R. Clarkson and subject matter expert J.D. Williams-Kovacs, University of Calgary

Flowback analysis is rate transient analysis flowback data or that early time production data that is gathered immediately after a well is hydraulically fractured. With flowback analysis various outputs can be derived; the primary ones being those related to hydraulic fracture characterization. In this course, students will learn how to determine whether or not flowback data is sufficient for a model based analysis, identify flow regimes and extract reservoir and hydraulic fracture properties, including hydrocarbon-in-place assessment.

We're pleased to annouce that the contents of Chris Clarkson's FBA course reference Chapter 14 - Flowback and Early-Time Production Data Analysis within Hydraulic Fracturing: Fundamentals and Advancements by Jennifer Miskimins, (Editor-in-Chief) which is published by the Society of Petroleum Engineers.
