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

The present invention relates generally to systems and processes for improved drag reduction estimation and measurement and more specifically to portable drag reduction analyzers and processes for upscaling drag reduction data for a variety of field applications. A drag reduction parameter ΔB for the fluid mixture is used for determining drag reduction for a fluid mixture in an oil field or pipeline operation.
