SPE Workshop: Diagnostic Fracture Injection Test (DFIT) - Processes and Applications 26 - 27 Oct 2016 BP Westlake Houston, Texas, USA


Wednesday, October 26

07:00 - 08:00
08:00 - 08:30
08:30 - 10:00
Session 1: DFIT Job Design and Execution
Session Chairpersons John Kalfayan, RDS; Mac Rincon, Oxy

This session will cover best practices and operational procedures when pumping a DFIT. It will explore how much rate and what volume to inject, how and what to monitor during the tests, and common issues and how to prevent them. 

10:00 - 10:30
10:30 - 12:00
Session 2: DFIT Analysis - Theories, Concepts, and Concerns
Session Chairpersons Larry Britt, NSI; Neal Hageman, IPT Energy Services

Is DFIT being used to determine information about the fracturing mechanics, the reservoir properties, or both? This session will explore the theories, concepts, and concerns of the DFIT and assess how this fundamental question affects the test design.

12:00 - 13:00
13:00 - 14:30
Session 3: DFIT Analysis - Data Signatures
Session Chairpersons Robert Hawkes, Trican; Steve Schubarth, Schubarth Inc.

Ever since Nolte developed an analysis of the pressure decline signature to provide fluid efficiency for determination of fracture parameters, engineers have refined the technique by using a combination of specialized square root-t, G-function, pressure derivatives, and log-log plots. This session will show recent advances in pressure decline analysis with examples of both before and after-closure signatures in some of our more challenging formations.

14:30 - 15:00
15:00 - 16:30
Session 4: DFIT Post-Analysis - Data Utilization
Session Chairpersons Lucas Bazan, Bazan Consulting

This session will focus on the larger utilization of mechanical or reservoir characteristics obtained from DFIT and after closure analysis (ACA).  Aspect related to production forecasting, reservoir and geology characterization, and calibration with core and logs will be explored.

07:30 - 08:00
08:00 - 09:30
Session 5: DFIT Post-Analysis - Modelling
Session Chairpersons Marisela Sanchez-Nagel, Oilfield Geomechanics; Peter Smeallie, ARMA

Numerical modeling of the rock mass behavior during a DFIT is done to consider the effects of critical aspects such as presence of natural fractures, local stress changes, pore pressure, poroelastic effects, mechanical properties of the rocks, fine layers, near wellbore effects and others.   This session will discuss the relevance and merits of these type of analyses, and how they can help in the interpretation of DFITs.

09:30 - 10:00
10:00 - 11:30
Session 6: Vertical Pilot Wells
Session Chairpersons James Rodgerson, Rodgerson Completion Consulting; Jeremy Viscomi, PTTC

The objective of this session is to explore injection tests techniques and best practices for vertical data wells. Vertical data wells are generally used to gain a better understanding of formation properties of potential pay and bounding intervals within a given geographical area.  Presenters will demonstrate the injection techniques deployed and how they are used to validate data modeled assumptions.

11:30 - 13:00
Panel Discussion Wrap-Up and Lunch
Moderator(s) Robert Hawkes, Trican; Dave Cramer, ConocoPhillips
