摘要： Methods for treating a subterranean formation include providing a first treatment fluid comprising a plurality of degradable diverting agents, introducing the first treatment fluid into the subterranean formation via a wellbore, and allowing a portion of the plurality of degradable diverting agents to divert a flow of at least a portion of the first treatment fluid or a portion of a second treatment fluid from a first location within the wellbore to a second location within the wellbore. The plurality of degradable diverting agents includes a blend of polylactic acid (PLA) and an acid-soluble hard particulate. Compositions for treating a subterranean formation include the plurality of degradable diverting agents.

摘要： Catalyst extraction from polycrystalline diamond table may be achieved by treating with a halogen (in the gas phase or dissolved in a nonpolar organic solvent) to convert the catalyzing material to a salt. Then, polar organic solvents may optionally be used to leach the salt from the polycrystalline diamond table. The polycrystalline diamond (with the salt of the catalyzing material present or at least partially leached therefrom) may be brazed to a hard composite substrate to produce a cutter suitable for use in a matrix drill bit.

摘要： Certain metal surfaces are often unable to be effectively contacted with fluids containing hydrofluoric acid due to significant corrosion issues. Titanium and titanium alloy surfaces represent but one example. Corrosion inhibitor compositions comprising boron-hydroxyalkyl(amine) compound(s) can be used to suppress such metal corrosion, including that taking place on titanium and titanium alloy surfaces, particularly those in a wellbore or in fluid communication with a wellbore.

摘要： Methods of inhibiting corrosion of metal surfaces by aqueous acids are described. The methods include combining a corrosion inhibiting aqueous emulsion with the aqueous acid solution to form a treatment fluid and contacting the metal surface with the treatment fluid. The corrosion inhibiting aqueous emulsion includes one or more silicone polymers having hydrophilic functional groups.
