Minimize Losses and Maximize Profits

Our Products

A unique blend of resilient sealant components, including graphite, minerals, and polymers designed to help reduce seepage losses during the drilling of a depleted zone. BLACK JACK™ is temperature stable up to 450º F and disperses easily in Diesel, Oils, synthetic and aqueous-base fluids.

BLACK JACK™ can be mixed in all types of drilling and completion fluids. Additions of up to 30 ppb of this unique product will not increase the ECD, thus helping to reduce or eliminate seepage loss.
