摘要： A method of formulating an oil-based wellbore fluid, the method comprising adding at least a plurality of conductive carbon black agglomerates or pellets having an average size of at least 500 μm to an oleaginous base fluid, and applying energy to the oil-based wellbore fluid to disperse the plurality of conductive carbon black agglomerates or pellets into the oleaginous base fluid as finer particles than the agglomerates or pellets.

摘要： An environmentally responsible iron chelating additive and method for removing hydrogen sulfide or sulfide ions from drilling and packer fluids and preventing settling of precipitates. Iron chelating agents selected from the group consisting of ferrous lactate, ferrous gluconate, ferrous bis glycinate, ferrous citrate, ferrous acetate, ferrous fumarate, ferrous succinate, ferrous sacchrate, ferrous tartarate, ferrous glycine sulfate, ferrous glutamate, ferrous ascorbate, ferrous polymaltose, or a combination thereof, may be used. When the fluids are oil based, the iron chelating agents are added to the water phase of an emulsion, and the emulsion is added to the fluid. Viscosifiers may also be added to the drilling fluid with the emulsion.

摘要： A method of hydraulically fracturing a subterranean formation penetrated by a wellbore comprises: providing a diverting fluid comprising a carrier fluid, a first superabsorbent polymer and a second superabsorbent polymer, the second superabsorbent polymer having a shape, or a composition, or a combination thereof different from that of the first superabsorbent polymer; injecting the diverting fluid into the subterranean formation; and injecting a fracturing fluid into the formation after injecting the diverting fluid. A viscosity modifying agent can be present in the diverting fluid. Superabsorbent polymers can also be used to develop a temporary filter cake at the formation face to reduce or eliminate the fluid leakoff out of the wellbore.

摘要： An oil-based drilling fluid and method of preparing an oil-based drilling fluid are disclosed. The oil-based drilling fluid comprising a base oil continuous phase, an aqueous discontinuous phase, and at least one rheology modifier. The at least one rheology modifier including an alkaline-earth diamondoid compound. The method of preparing the oil-based drilling fluid including mixing a base oil, at least one emulsifier, and at least one wetting agent to form a first mixture, adding and mixing at least one rheology modifier into the first mixture to form a second mixture, adding and mixing at least one fluid-loss control additive into the second mixture to form a third mixture, adding and mixing a brine solution into the third mixture to form a fourth mixture, and adding and mixing a weighting additive into the fourth mixture to form the oil-based drilling fluid.
