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. WebThe test, in short, consists of a 3” X 1.25” metal pipe and shale. The pipe is weighed, and then rolled in a jar with 20 grams of the shale cuttings for 30 minutes at a set temperature. The tube is removed from the jar and dried in an oven for …
