Abstract
Disclosed is a method of generating microbubbles in oleaginous liquids which comprises adding a silicone oil to the oleaginous liquid and thereafter subjecting the liquid to mechanical forces in the presence of a gas. Also disclosed are oil base well drilling and servicing fluids having a low shear rate viscosity as measured with a Brookfield Viscometer at 0.5 rpm of at least 10,000 centipoise and having incorporated therein microbubbles generated by the disclosed method, and a method of drilling a well wherein there is circulated within the wellbore during drilling the oil base, microbubble-containing fluid disclosed.

A method of generating gas microbubbles suspended in oleaginous liquids which comprises adding a silicone oil to the oleaginous liquid and thereafer subjecting the oleaginous liquid to mechanical forces in the presence of a gas.
An oil base well drilling and servicing fluid comprising an oleaginous liquid as the continuous liquid phase having incorporated therein one or more viscosifiers such that the fluid has a low shear rate viscosity as measured with a Brookfield Viscometer at 0.5 rpm of at least about 10,000 centipoise, a silicone oil for generating microbubbles in the oleaginous liquid, and microbubbles, wherein the microbubbles are generated by subjecting the silicone oil-containing oleaginous liquid to mechanical forces in the presence of a gas.
A chemical composition comprising:
- an oleaginous liquid;
- silicone oil;
- a viscosifier;
- and
- microbubbles, wherein the composition is a drilling fluid.
A chemical composition comprising:
- an oleaginous liquid;
- silicone oil;
- a viscosifier;
- and
- microbubbles, wherein the composition is a servicing fluid.
A process for drilling or servicing a wellbore in a subterranean formation wherein a drilling or servicing fluid is circulated in the wellbore, comprising:
- utilizing as the drilling or servicing fluid an oleaginous liquid, silicone oil and microbubbles.
