Described herein are compositions and methods that stabilize an injection fluid when exposed to reservoir conditions, reducing formation damage and increasing the amount of hydrocarbon recovered. Specifically, the formulation is a single-phase liquid surfactant package which comprises an anionic surfactant and optionally one or more secondary surfactants.

Injection fluids comprising an anionic surfactant for treating unconventional formations

Compositions and methods that can be used to sequester carbon dioxide within a subterranean formation are described. The methods can include contacting carbon dioxide present in the subterranean formation with a complexing agent, resulting in precipitation of a carbonate or bicarbonate salt of the complexing agent within the subterranean formation.

Compositions and methods for carbon dioxide solidification

Provided herein are liquid polymer (LP) compositions comprising a synthetic (co)polymer (e.g., an acrylamide (co)polymer), as well as methods for preparing inverted polymer solutions by inverting these LP compositions in an aqueous fluid. The resulting inverted polymer solutions can have a concentration of a synthetic (co)polymer (e.g., an acrylamide (co)polymer) of from 50 to 15,000 ppm, and a filter ratio of 1.5 or less at 15 psi using a 1.2 μm filter. Also provided are methods of using these inverted polymer solutions in oil and gas operations, including enhanced oil recovery.

Methods for hydrocarbon recovery

Described are compositions and methods for use in oil and gas operations. The methods can decrease pressure drop along a lateral segment of a wellbore in an unconventional subterranean formation.

Compositions containing friction reducers and methods of using thereof in oil and gas operations

Provided herein are compositions comprising borate-acid buffers, as well as methods of using these compositions in oil and gas operations, including enhanced oil recovery (EOR) operations, fracturing operations, stimulation operations, etc.

Use of a borate-acid buffer in oil and gas operations

Disclosed are compositions and methods for the pressure protection of existing wells during infill drilling operations.

Compositions and methods for pressure protection

Disclosed are foam precursor compositions, foamed compositions, and methods of using these foamed compositions for the stimulation of unconventional reservoirs.

Methods for foam stimulation

Disclosed are compositions and methods for use in oil and gas operations.

Compositions for use in oil and gas operations
