ABSTRACT:
The present invention discloses the use of calcium sulfonate based greases compounds for use in application where the compounds are continuously, periodically or intermittently exposed to fluids that tend to contamination, erode, ablate or otherwise remove or interfere with the compounds ability to protect contact surfaces such as those present in threaded connections, and, especially in threaded connections associated with oilfield applications. The present invention also discloses methods for making and using such greases and compounds in application where the compounds are continuously, periodically or intermittently exposed to fluids that tend to contamination, erode, ablate or otherwise remove or interfere with the compounds ability to protect contact surfaces.
