A system for slowly releasing an oil-soluble well treatment agent into a well or a subterranean formation includes a composite of the oil-soluble well treatment agent associated with a second component. The amount of the oil-soluble well treatment agent in the composite is from 20 to 35 weight percent and the average particle size of the oil-soluble well treatment agent in the composite is less than or equal to 1 micrometer. The composite may further contain a water-soluble well treatment agent.

A method of treating a well or a subterranean formation with an aqueous treatment fluid containing one or more oil-soluble, water-insoluble well treatment agents. The fluid includes an aqueous dispersion containing the well treatment agent in an amount from 25 to 60 weight percent. The volume average particle diameter of the oil-soluble well treatment agent in the fluid may be less than or equal to 2.5 microns. The fluid may further contain a water-soluble well treatment agent.

Methods for creating or enhancing a fracture in a subterranean formation include introducing a pad fluid into a formation at a rate and pressure sufficient to create or enhance at least one fracture therein. The pad fluid can include a pad base fluid, micro-proppant particulates, a gas-generating chemical, and an activator, and wherein either the gas-generating chemical or the activator or both are encapsulated. The methods can include placing the micro-proppant particulates, etc. into the fracture; releasing the activator from its encapsulation; reacting the gas-generating chemical and the activator in the fracture so as to generate gas and heat, thereby creating or enhancing at least one microfracture therein; introducing a fracturing fluid into the formation, wherein the fracturing fluid comprises a fracturing base fluid and macro-proppant particulates and placing the macroproppant particulates into the fracture so as to form a proppant pack therein.

Discrete, individualized carbon nanotubes having targeted, or selective, oxidation levels and/or content on the interior and exterior of the tube walls can be used for nanotube-mediated controlled delivery of degradative molecules, such as oxidizers and enzymes, for oil-field drilling applications. A manufacturing process using minimal acid oxidation for carbon nanotubes may also be used which provides higher levels of oxidation compared to other known manufacturing processes.

Methods and compositions comprising an emulsion or a microemulsion for use in various aspects of the life cycle of an oil and/or gas well are provided. In some embodiments, the emulsion or the microemulsion comprises water, a solvent, and a surfactant, and optionally, one or more additives.

Methods and systems for facilitating extraction of subterranean hydrocarbons from a geologic structure. The present methods include causing corrosion of a base metal within a geologic structure to produce a gaseous product to increase pressure and form fractures in the geologic structure. Some embodiments of the present methods include injecting a fluid composition comprising the base metal into a wellbore (e.g., into a geologic structure via the wellbore).

Electro-responsive hydrogel particles are flowed into a first wellbore formed in a subterranean formation. An electric circuit is established between the first wellbore and a second wellbore formed in the subterranean formation. An electric current is applied through the electric circuit, thereby exposing the electro-responsive hydrogel particles to an electric field and causing at least one of swelling or aggregation of the electro-responsive hydrogel particles to form a flow-diverting plug within the subterranean formation. Water is flowed into the first wellbore to increase hydrocarbon production from the second wellbore.
