| titleOfInvention | Oil well drilling fluids with improved anti-settling properties and methods of providing anti-settling properties to oil well drilling fluids |
| abstract | An improved drilling fluid with enhanced anti-settling properties useful for oil well drilling systems is described. The invention includes a process for providing anti-settling properties to oil invert (i.e., water in oil emulsion) based fluids. The drilling fluid/drilling mud invention contains at least one copolymer reaction product of which the reactants comprise at least one ethylenically unsaturated carboxylic compound and at least one alpha-olefin. As an alternative embodiment one or more rheologically-active clays including organoclays and smectite clays in combination with such copolymer reaction product are also added to the drilling fluid. The invention also includes an anti-settling additive comprising a rheologically active clay and the above described copolymer. |
