Reagents and materials for oil-based drilling fluids

R-MOD Viscosifier

R-MOD is a complex blend of dimer and trimer acids. It is especially formulated to improve rheological and suspension characteristics of all base fluids. The product increases low shear rate viscosities and gel strengths for improved hole cleaning. This permits high rates of penetration while maintaining wellbore stability. The recommended normal treatment range is 1.0-3.0 lbs/bbl.

 

MUL 1 Primary emulsifier

MUL 1 is a specially formulated modified crude tall oil in diesel designed to create stable emulsions of water and brine in refined or crude oil, esters, ethers, synthetics, mineral oil, or other hydrocarbons. It lowers interfacial tension between oil and brine and stabilizes emulsions of water in oil. Shales and clays can be drilled with gauge hole and increase of hole penetration. The recommended normal treatment range from 2.0 to 12.0 lbs/bbl.

 

MUL 11 Primary emulsifier

MUL 11 is a specially formulated derivate of vegetable oil designed to create stable emulsions of water and brine in refined or crude oil, esters, ethers, synthetics, mineral oil, or other hydrocarbons. It lowers interfacial tension between oil and brine and stabilizes emulsions of water in oil. Shales and clays can be drilled with gauge hole and increase of hole penetration. The recommended normal treatment range from 2.0 to 12 lbs/bbl

 

MUL 2 Secondary emulsifier

MUL 2 is a specially formulated tall oil fatty acid in a polyamide solution in diesel. It is a concentrated blend that aids in forming stable emulsion between synthetic oils, ethers, esters, poly-olefins and internal olefins as well as in calcium or sodium brines. MUL 2 tightens the emulsion and assures that solids are oil wet, making sure that the filtrate is water-free. The oil emulsion will drill shales and clays with excellent hole stability. The recommended normal treatment range is 2.0-8.0 lbs/bbl.

 

THIN Thinner OBM system

THIN is a powerful invert oil mud thinner, particularly effective in high weight muds where unacceptably high gel strengths can be generated. The material does not adversely affect other mud properties and in some cases as been shown to improve HTHP fluid loss. The recommended normal treatment range is 0.50-1.50 lbs/bbl.

 

OWA-100 Wetting agent

OWA-100 is a specially formulated amido imidazoline product that is blended in diesel. OWA-100 promotes rapid oil wetting of drill solids and barite in and between synthetic oils, ethers, esters, poly-olefins and internal olefins as well as in calcium or sodium brines. OWA-100 is a highly effective oil-wetting agent that prevents loss of favorable mud rheology that can occur from contamination by water-wet solids and water influx.

 

O-BENT Gelling agent

O-BENT rheological additive is an organic ammonium montmorillonite organoclay, for oil base drilling muds. O-BENT is applied to increase carrying capacity and suspension properties, providing support for weight materials and improved cuttings removal. O-BENT also aids in filtercake formation and filtration control. The recommended normal treatment range is 2.0-8.0 lbs/bbl.
