Core Fluid Preservation and Quantification in Liquid Rich Organic Shales

presented by 

Steve Brackeen
 (VP of Petrophysics, with Primexx Energy Partners in Dallas, Texas)


Unconventional core analysis of organic rich mudstones was developed in gas rich reservoirs where oil and water measurements were of little concern or importance.  As the industry has turned to exploration and development of liquid rich organic mudstones, core analysis has not been adequately modified to address the associated challenges.  Using rotary sidewall core data from 5 wells in the Southern Delaware Basin, a review of three common unconventional fluid analysis procedures will be examined, highlighting the strengths and deficiencies of each.  Core fluid preservation protocols will also be discussed, and a novel and inexpensive method of wellsite rotary sidewall core fluid preservation will be introduced that allows for non-destructive in-situ fluid preservation and quantification.
