Gel strength: a measure of the electrical attraction forces in a gel. Gel strength is the minimum shearing stress that will permanently defrom a gel such as drilling mud. Gel strength is usually reported in lb/100 sq ft. Common gel strength measurements are initial (after setting for 10 minutes). Gel strength defines the ability of the drilling mud to hold solids in suspension an gives an indication of the thixotropic properties of the muh. Gel strenth is measured on a viscometer of gelometer. Ngu?n: http://tinyurl.com/272rnz5
