Abstract:
A method for joining tubulars that includes preparing a fast-setting epoxy compound, wherein the preparing comprises: mixing a first micro-crystalline filler into an epoxidized glycerol fatty ester, mixing a titanium oxide, a first talc, and a flatting agent into the first mixture, mixing a hydrocarbon resin into the second mixture, and mixing a hardenable epoxide containing liquid to form an epoxy base. A second micro-crystalline filler, a second talc, and a glycidyl ether are mixed into a phthalocyanine, a hybrid reactive polyamide is mixed into this mixture, a modified aliphatic amine is mixed into the resulting mixture, and a methylamino accelerator is added to form an epoxy accelerator. Substantially equal portions of the epoxy base and the epoxy accelerator are mixed to form the fast-setting epoxy compound.

Abstract:
Disclosed is an effective thermal grease comprising a hyperbranched olefinic fluid and a thermally conductive filler. Property-modifying additives and fillers may also be included. The hyperbranched olefinic fluid is selected to have an average of at least 1.5 methine carbons per oligomer molecule and at least 40 methine carbons per one thousand total carbons. The thermal grease exhibits a flash point of 180° C. or higher, a pour point of 0° C. or lower, and a kinematic viscosity at 40° C. of no more than 200 cSt (0.0002 m 2/s). The composition may offer improved thermal conductivity, reduced tendency to migrate, and lower cost when compared with many other thermal greases, including silicone-based thermal greases.
Abstract:
The present disclosure relates to greases containing metal sulfonate thickeners. In one example the thickener may be a calcium sulfonate thickener. In other examples grease may contain a combination of a metal sulfonate thickener and another thickener, such as a metal complex soap grease, detergent, or non-soap thickener. The grease may be formulated to meet specific performance criteria relevant to lubrication of a roller cone drill bit in downhole conditions. The disclosure also relates to a roller cone drill bit containing a grease of the disclosure.
