Drill Spot is a free flowing concentrated powder formulated to make an oil base spotting mud. This spotting mud releases the stuck drill string and stops the migration of spot away from the stuck interval. Drill Spot can be mixed to prepare spotting mud of weight up to 18 ppg by using the given table.
Oxidized asphalt, organophilic clay, lubricants, high molecular weight fatty acids, emulsion stabilizers and surfactants are blended to Drill Spot to extricate severely stuck pipes.
Spotting fluids made by Drill Spot, when placed opposite the area of stuck pipe functions in duel way (i) it penetrates the mud cake, disintegrates it, equalizing the differential pressure hence stuck pipe is released, (ii) provides lubrication between drill string and mud cake resulting in increased mobility of drill string
