Abstract

"Since invert emulsions are being applied as drilling fluids to cope with special drilling and completion problems, evaluations of existing and new types of emulsions are needed. Three types of emulsions are evaluated in this study: (1) type A emulsions prepared with a commercial emulsifier, (2) type B emulsions prepared by adding clay to the external phase, and (3) type C emulsions containing no externally added emulsifier.

Standard testing procedures were used to measure the viscosity and filtration properties of the emulsions studied. Interfacial tension measurements were made using a technique described in the literature. The degree of stability for the emulsions studied was determined by the viscosity ratio method developed during this study.

A discussion of the effects of some of the recognized variables on the properties mentioned above is presented. The three types of emulsions studied are compared on the basis of the effects of the variables and on theoretical considerations.

Type A emulsions as investigated were found to be suitable for all conditions under which the use of an invert emulsion fluid is warranted. Type B emulsions as investigated were found to be suitable only over a narrow range of temperatures and phase volume ratios. Type C emulsions exhibited excessive filter losses over all phase volume ratios investigated and were eliminated from further consideration on this basis"--Abstract, page ii.
