Methods of treating a subterranean formation including shale include preparing a treatment fluid by mixing an aqueous base fluid and a dry polyvinyl pyrrolidone (PVP) in flake or powder form having a molecular weight between about 500,000 and about 2,000,000 and introducing the treatment fluid in the subterranean formation.

Compositions and methods for inhibiting shale and preventing shale accretion

A method may include: circulating a drilling fluid in a wellbore, wherein the drilling fluid includes: an aqueous phase; and a reclaimed carbon black additive; and drilling into a subterranean formation to extend the wellbore while the drilling fluid is circulated therein.

Reclaimed carbon black drilling fluid additive

Described herein are fluids used to inhibit swelling of clay or shale formations, where the fluids include a drilling fluid and a clay stabilizer that include a potassium salt with a plurality of cations and are injectable into a wellbore.

Potassium salt treatment fluids for clay stabilization

De-oiled lost circulation materials and methods of using such materials to, for example, reduce fluid loss are provided. In some embodiments, such methods include introducing a first treatment fluid including a base fluid and a de-oiled plant material into a wellbore penetrating at least a portion of a subterranean formation including a loss zone; and allowing the de-oiled plant material to at least partially plug the loss zone.

De-oiled lost circulation materials

Methods of treating a subterranean formation and treatment fluids are discussed herein. The methods generally include treating the subterranean formation with a rare earth oxide by providing a first treatment fluid having a density of at least about 10 pounds per gallon including a rare earth oxide; and introducing the first treatment fluid into the subterranean formation.

Rare earth oxide as a weighting and bridging agent

The present disclosure may be directed to defoaming methods and compositions. A method of treating a subterranean formation may comprise providing a defoaming composition, wherein the defoaming composition comprises a tall-oil-derived surfactant. The method may further comprise mixing the defoaming composition with an aqueous fluid to form a treatment fluid such that foaming in the treatment fluid is reduced, wherein the treatment fluid is a water-based fluid. The method may further comprise placing the treatment fluid into the subterranean formation.

Defoaming composition comprising a tall-oil-derived surfactant

A treatment fluid comprising a peroxide source and a perovskite family catalyst is useful in processes for breaking the gelled component of a gelled fluid used in downhole operations. In particular, the treatment fluid can be useful in fracturing operations where it can not only break the gelled component of the fracturing fluid but the gaseous oxygen generated by the peroxide source and perovskite family catalyst can be used to further fracture a subterranean formation.

Peroxide containing formation conditioning and pressure generating composition and method

The present disclosure relates to a process for obtaining carbon black powder with a sulfur content of less than 0.07%. The process includes step of reacting carbon black powder with a sulfur content of 1-2% with an alkali metal or salt thereof, in a fluid media, at a temperature in the range of 100&#xb0; C. to 350&#xb0; C. and pressure in the range of 10 to 500 psig. It is found that in accordance with the process of the present disclosure, the sulfur content was reduced substantially from that of about 1.25% to that of 0.05%, resulting in about 96% desulfurization.

Process for obtaining carbon black powder with reduced sulfur content

The present disclosure provides a method for isolation and purification of sodium sulfide (NaS) formed during desulfurization of petroleum residue. The process involves treating a sludge containing NaS obtained during desulfurization of petroleum residue with a mixture of at least one organic solvent and water.
