WebJul 11, 2013 · The reactivity of shale toward water is a much studied and debated topic. For years, the swelling of shale, which is due to the ingress of water and hydration of metal cations, has been considered the “best documented” and main failure mechanism. WebJan 4, 2006 · In reactive shales, the HPWBF helped minimize hole washout, optimize hole cleaning and improve the quality of cementing jobs. The HPWBF enabled a solids removal efficiency (SRE) in the 85% range, rivaling invert emulsion systems. Product consumption and discharge volumes were significantly lower compared to conventional WBFs.
