Abstract:
A drilling fluid system comprising at least one of the following modules:an alkaline first module that contains (a) a source of caustic, (b) a natural wax, (c) a natural thinner, (d) glycerol, and (e) phosphoric acid and/or boric acid,a second module prepared by reacting (f) aluminum metal with the components of said alkaline first module thereby forming a soluble alkali metal aluminate;a third module containing said components of said first module in combination (g) with at least one of an alkali metal phosphate and sodium silicate;a fourth module containing said components of said first module in combination with (h) a saturated or unsaturated carboxylic acid source, ora fifth module containing said components of said first module in combination with (h) a saturated or unsaturated carboxylic acid source, and (g) at least one of an alkali metal phosphate and sodium silicate,wherein said third, fourth and fifth modules can be used for simultaneously thinning and increasing the lubricity of a drilling mud thus improving penetration of a drill bit, and said second module can be used for thickening a drilling mud.
