A drilling fluid includes a base fluid and a circulation loss reducing additive package having a polysaccharide, a cellulose derivative and a pH controlling component.

Drilling fluid with circulation loss reducing additive package

A combustible fuel for diesel engines and a process for forming same in the form of a water in hydrocarbon emulsion wherein the mean water drop diameter is .ltoreq.4 .mu.m with a maximum diameter of .ltoreq.10 .mu.m.

Water in viscous hydrocarbon emulsion combustible fuel for diesel

A low viscosity, non-aging hydrocarbon in water emulsion formed from a viscous hydrocarbon comprises from about 70 to 80%/wt. oil, from about 20 to 30%/wt. water, from about 0.1 to 5.0%/wt. of an emulsifying agent, and an average oil droplet size of greater than or equal to 15 microns wherein the emulsion is characterized by a viscosity of less or equal to 1500 centipoise at 80.degree. F. and substantial non-aging over time wherein the change in viscosity of the emulsion is less than 100 centipoise per month.

Emulsion of viscous hydrocarbon in water which inhibits aging

A stable, low viscosity bimodal oil in water emulsion having an emulsifier, a continuous water phase and a discontinuous oil phase having an oil:water ratio of from about 70:30 to about 85:15 by weight, the discontinuous oil phase being characterized by two distinct oil droplet sizes D.sub.L and D.sub.S wherein D.sub.L is about 10 to 40 microns and D.sub.S is less than or equal to 5 microns, the ratio of D.sub.L /D.sub.S is greater than or equal to 4 and about 45 to 85% by weight of the oil is in oil droplet size D.sub.L.

Bimodal emulsion and its method of preparation

A method for the preparation of a hydrocarbon in water emulsion from viscous hydrocarbons wherein aging of the emulsion over time is substantially eliminated comprises forming a concentrated emulsion characterized by a water content of less than or equal to 15%/wt. and an average oil droplet size of less than or equal to 4 microns and thereafter forming a final emulsion by diluting the concentrated hydrocarbon in water emulsion with water so as to obtain a water content of less than or equal to 30%/wt. and stirring said diluted emulsion so as to obtain a final hydrocarbon in water emulsion having an average oil droplet size of greater than or equal to 15 microns.
