A Study Of Invert Emulsion Drilling Fluids, Edward R. Tegland
Masters Theses
"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 …
