| titleOfInvention | STABLE EMULSION DRILLING FLUIDS |
| abstract | A method for reducing the density of a stable emulsion drilling fluid may include using a stable emulsion drilling fluid comprising: an aqueous liquid; a biopolymer; an emulsifier; solid particles; and an oil; the stable emulsion drilling fluid being able to remain in a quiescent storage at about 70 F and at atmospheric pressure without phase separation for about 8 hours or more; circulating the stable emulsion drilling fluid through a drill string and an annulus; adding additional oil to the stable emulsion drilling fluid to decrease the density of the stable emulsion drilling fluid and to produce a stable low density emulsion drilling fluid; and circulating the low density stable emulsion drilling fluid through the drill string and the annulus. |
