PRODUCT DESCRIPTION PIPE FREE additive is used in diesel oil or in oil-based muds to form a highly effective stuck-pipe spotting fluid. PIPE FREE enables spotting fluids to penetrate and "crack" the water-based-mud filter cake with an extremely high-fluid-loss and solids-free filtrate. These features allow the PIPE FREE and oil solution to pass through the water- based-mud filter cake between the stuck pipe and wellbore wall to facilitate freeing differentially stuck pipe. PHYSICAL & CHEMICAL PROPERTIES Appearance Dark brown to black colored liquid pH 5.6 - 6.6 (1% aqueous solution) Specific Gravity 0.90gm/cm3 Solubility Slightly soluble in water APPLICATION PIPE…

Spot in hole prior to logging operations. Allows more true weight to bit. Spot in key seats to reduce torque, drag, and sticking problems. Apply NC-LUB G fine beads for torque and drag in coil tubing operations or with work strings. Lubricant for OBM or SBM. Aids in prevention of differential sticking when using OBM or SBM. Aids in directional changes or sliding. RECOMMENDED TREATMENT Concentrations…

PRODUCT DESCRIPTION NC-DRILL is a proprietary blend of synthetic fluids specifically engineered to enhance the rate of penetration while drilling. PHYSICAL & CHEMICAL PROPERTIES Appearance Transparent colorless liquid pH 7.5 - 9.0 (5% aqueous solution) Specific Gravity 0.79 - 0.81g/cm3 Solubility Insoluble in water APPLICATION Enhance rate of penetration. Increase the ability to slide while directionally drilling. Increase lubricity. Effective in small concentrations. RECOMMENDED TREATMENT 1 - 4% by volume in water-based drilling fluids. Add 3 - 10% NC-DRILL in sweeps and pump as needed or inject directly down hole. These volumes may then be incorporated into the active mud…

PRODUCT DESCRIPTION NC-DD a blend of water-soluble anionic surfactants that can be used in fresh or saltwater and in low-solids muds as a wetting agent. PHYSICAL & CHEMICAL PROPERTIES Appearance Light Green liquid pH 8.2 Specific Gravity 1.01 - 1.02g/cm3 Boiling Point 98.9°C Flash Point > 93.3 °C Solubility Partially soluble in water APPLICATION Increase the drilling rate by improving bit cleaning and release of cuttings from the bit surface. Retard breakup of cuttings in the annulus. Promote settling of cuttings at the surface. Counteract the sticking tendencies of clays and thereby reduce wall-packing, bit-balling, booting-off, and formation of mud…

PRODUCT DESCRIPTION NC-CLEAN is a heavy-duty, water-soluble, dynamic surface cleaner. It can be used directly or watered down. The agent act to make oily surface clean easily. PHYSICAL & CHEMICAL PROPERTIES Appearance Clear, Blue Liquid pH 11 - 12 (5% aqueous solution) Specific Gravity 1.024 - 1.036 g/cm3 Bulk Density 53 - 8.63 lbs/gal Boiling Point 170.8°C Melting Point -70 °C Solubility Soluble in water APPLICATION NC-CLEAN is used for cuttings wash solution when using oil-based mud.
