Delineating Stacked Pay with Existing and Emerging Diagnostic Tools
by K. Haustveit (Devon Energy), H. Greenwood (Devon Energy)
Here at RDS, we have carved out a couple of niche specialties in the industry — Diagnostic Fracture Injection Tests (DFITs) and offset-well pressure monitoring. Although DFIT technology was pioneered many years ago, we continue to capture a significant number of these tests due to the valuable information they provide. Often, these tests are ordered by reservoir engineers simply hoping to improve the input values of their models, but lately, we have noticed some innovative individuals taking a different slant on the more traditional applications. These engineers understand DFITs to be another tool in their toolbox that helps to uncover those reservoir mysteries and unknowns, and in the case presented in this whitepaper, the authors use the findings from DFITs to evaluate potential pressure barriers as part of a multi-pronged approach to delineating stacked pay.
Few folks will argue that stacked pay is not an attractive quality when evaluating an asset. However, it does add another level of complexity in determining the best approach for proper development. Understanding reservoir qualities and fracture geometries are vital in this endeavor. This paper discusses the use of DFITs, offset pressure monitoring, radioactive proppant tracer (RA), and electrically conductive proppant in order to better reach that understanding. The authors make a clear case and point out that better data, in regards to fracture barriers and fracture height, can directly aid in both optimization and risk mitigation. The authors also state that the costs of these tests are “easily offset and justified.”
Overall, this is a good read through the lens of an innovative and science/data-driven operator, that addresses prevalent issues in the development of stacked pay in unconventional reservoirs.

Diagnostic Fracture Injection Tests: Common Mistakes, Misfires, and Misdiagnoses
by R.D. Barree, J.L. Miskimins, and J.V. Gilbert, Barree & Associates.
Over the last twenty years, Diagnostic Fracture Injection Tests, or DFIT’s, have evolved into commonly used techniques that can provide valuable information about the reservoir, as well as hydraulic fracture treatment parameters. Thousands are pumped every year in both conventional and unconventional reservoirs. Unfortunately, many tests that are pumped provide poor or no results due to either problematic data acquisition or incorrect analysis of the acquired data.
This paper discusses common issues and mistakes made while acquiring DFIT data, and provides details of what the author believes to be guidelines and rules of thumb on how to avoid them. It goes on to addresses potential problems that can occur during DFIT analysis, and more specific issues such as poor ISIP data from perforation restriction, loss of hydrostatic head, gas entry and the resulting phase segregation, and the use of gelled fluids.
Although industry thought-processes may have changed slightly since the paper was published in 2014, the ideas presented by the author are as relevant as ever — remember, you only have one shot at performing a DFIT correctly!
