Pheno Seal is a chemically stable thermoset laminate used as a drilling additive. It has superior performance in lost circulation, bit balling, and pipe and casing sliding in all water, oil, and synthetic based fluids and cements.
Pheno Seal is manufactured from laminate sheets which are ground into flakes and sized to provide maximum sealability using minimum pounds per barrel. Pheno Seal is safe and effective in all water, oil, and synthetic-based muds, and is also compatible with squeezes and cements. Pheno Seal is one of the most effective lost circulation materials on the market, offering tremendous performance advantages in cases of fractured formations, seepage loss, and bit balling.
Pheno Seal provides a hard, smooth, pressure resistant barrier between the drillstring and wellbore. This reduces the pressure differential along the wellbore, as well as reducing the adhesion between the drillpipe and filtercake. Unlike granular materials, Pheno Seal does not degrade filtercake quality.
The strong, thin edges of each Pheno Seal particle cut away at formation build-up on bits and stabilizers like a knife blade. Pheno Seal also contains approximately 7 times more particles per pound than nut plug. Pheno Seal’s inherent hardness, multiple cutting edges, and optimum hydraulic shape allow for an effective and economical solution for controlling formation buildup on bits and stabilizers.
