This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 175537, “Novel Proppant Surface Treatment Yields Enhanced Multiphase- Flow Performance and Improved Hydraulic-Fracture Cleanup,” by Terry Palisch, Mark Chapman, and Joshua Leasure, SPE, Carbo Ceramics, prepared for the 2015 SPE Liquids-Rich Basins Conference—North America, Midland, Texas, USA, 2–3 September. The paper has not been peer reviewed.
This paper describes the development and testing of a new proppant designed to exhibit a neutrally wet surface. The modified surface does not have a preferential affinity for oil, gas, or water and therefore will not promote the preferential entrapment of any phase within the proppant pack. This proppant technology and the results described in this paper should be useful for completions, production, and the work of reservoir engineers dealing with hydraulically fractured wells, particularly in oil- and condensate-rich reservoirs that are particularly challenged by multiphase flow.
