摘要:
The present technology relates to a process for enhancing hydrocarbon production from a shale formation. In particular, the present technology relates to a process wherein a treatment fluid comprising a water soluble delayed release carbonate-dissolving agent is introduced into the shale formation after or as part of a hydraulic fracturing process. The present technology also relates to a treatment fluid that can be used in such a process.

Self-suspending proppants including proppant particles coated with a CO2-philic coating are provided. The CO2-philic coating may be lightly crosslinked and may have a physical structure that constrains CO2 molecules. Methods of making self-suspending proppants may include coating a proppant particle with a polymerizable precursor material of a CO2-philic material and polymerizing the polymerizable precursor material to form a self-suspending proppant are also provided. Additionally, hydraulic fracturing fluids that may include a CO2-based fluid and the self-suspending proppants and methods of treating subterranean formations by contacting a subterranean formation with hydraulic fracturing fluid and propagating at least one subterranean fracture are provided.

A method of stabilizing one or more clays within a subterranean formation comprises forming at least one treatment fluid comprising anionic silica particles, cationic silica particles, and at least one base material. The at least one treatment fluid is provided into a subterranean formation containing clay particles to attach at least a portion of the anionic silica particles and the cationic silica particles to surfaces of the clay particles and form stabilized clay particles. A method of treating one or more clays contained within a subterranean formation, and a treatment fluid for a subterranean formation.

Disclosed is an alkaline earth metal peroxide concentrate, or fluidized suspension, for addition to aqueous hydraulic fracturing fluids to efficiently decrease the viscosity of the hydrated, hydrophilic polysaccharide polymer in the system. The concentrate comprises a hydrophobic, water insoluble liquid, an organophilic clay suspension agent, a polar activator, a sparingly-soluble alkaline earth metal peroxide, and an anionic surfactant. Advantageously, these concentrations, or suspensions, exhibit high flash points, making them easier to transport using commercial transportation means.

摘要:
A method of well treatment designed to enhance recovery of resources from the well. A solution with an alkaline pH greater than 8 is introduced into the well and allowed to react in the well for at least a minimum period of time. A neutral solution with a pH near 7 is introduced into the well and allowed to remain in the well for at least a minimum period of time. Finally, a solution with an acidic pH of approximately 1 is introduced into the well and allowed to react in the well for at least a minimum period of time.
