Premium emulsifier application, performance, and product usage evaluation
Summary
Exploration and developmental assets, both conventional and unconventional, continue to pose new and more demanding drilling environments for which Operators must find economical solutions. One such environment is elevated bottom-hole temperature (BHT) in which the temperature exceeds 350°F and approaches 400°F. When using an OBM for drilling, most typical emulsifier packages begin to deteriorate around 350°F requiring increased product usage to maintain a stable emulsion. Even then, overall stability and performance may be affected. Furthermore, recent field trial results indicate the operational, technical, and commercial benefits of a premium high-temperature (HT) emulsifier in a non-HT application may be substantial. This study demonstrates how the implementation of a premium HT emulsifier in a non-HT environment (< 350°F) resulted in lower product usage, stronger emulsion (ES) values, and reduced overall fluid cost.
