Sep 18, 2013 the cement mill certificate includes three performance tests that merit close attention: false set, vicat setting time and strength. false set. false set is the tendency for cement mixtures to stiffen early, typically due to the sulfate in the cement reacting with the water to form gypsum crystals over the first few minutes of mixing.One mill dressed with the advanced glyphaloy milling technology was able to mill through a total of 79 composite plugs in the two wells. milling this record number of frac plugs in two wells in one trip per well meant time savings that translated to significantly reduced cost for the operator. previously, the maximum number of plugs milled with grinding mill.
