Westside: DFIT’s in the Bakken Three Forks: Are We Getting Our Money’s Worth?
Diagnostic Fracture Injection Tests (DFIT) have become the standard method for evaluating closure stress and reservoir parameters in unconventional plays. ConocoPhillips alone has performed over 50 DFIT’s in Bakken Three Forks (BTF) wells since 2010. In the process, it has been determined that DFIT’s conducted in down-spaced wells in the BTF play yield estimates of reservoir pressure that are often far less than the initial reservoir pressure - and sometimes sub-hydrostatic in wells that offset the parent well. Are these DFIT results reliable enough to aid in the design of treatments for infill wells and to guide in well-spacing decisions, or should they be heavily discounted due to inadequacies in the testing conditions? This presentation will highlight perplexing DFIT results and is intended to generate a spirited discussion amongst the attendees on the merits of DFIT’s in unconventional plays.
