Abstract: A method of recovering hydrocarbons from a (non-bitumen) heavy crude oil bearing reservoir with structural relief uses the combination of Y-Grade NGL and steam assisted gravity drainage. The method includes injecting steam and Y-Grade NGL into the reservoir through a vertical injection wellbore, displacing hydrocarbons within the reservoir using a combination of the steam, the unfractionated hydrocarbon mixture, and gravity drainage, and then producing the displaced hydrocarbons from the reservoir through a horizontal production wellbore that is positioned structurally lower than and offset from the vertical injection wellbore.

Abstract: Use of a synthetic form of Y-grade natural gas liquids when in a supercritical state for a variety of processes and across numerous industrial applications is described herein. The low viscosity, high density, and tunable solvent properties of synthetic supercritical Y-grade natural gas liquids are useful for example in control of chemical reactions and processes, and/or single or two-phase separations.

Abstract: A method of dehydrating proppant is achieved by pressurizing a proppant silo that is filled with proppant and injecting gaseous nitrogen into the proppant silo. The gaseous nitrogen is used to exhaust moisture from the proppant silo until the proppant is in a bone-dry condition. The moisture is exhausted from the proppant silo while maintaining a back pressure within the proppant silo. The bone-dry proppant can be mixed with a stimulation fluid and injected into a hydrocarbon bearing reservoir.

Abstract: Systems and methods for enhanced or improved oil recovery includes injecting a Y-Grade NGL enhanced oil recovery fluid through an injection well into a hydrocarbon bearing reservoir to mobilize and displace hydrocarbons. The Y-Grade NGL enhanced oil recovery fluid comprises an unfractionated hydrocarbon mixture. Simultaneously and/or subsequently, a mobility control fluid is injected into the hydrocarbon bearing formation. Hydrocarbons from the hydrocarbon bearing reservoir are produced through a production well or the same injection well.

Abstract: A method for enhanced or improved oil recovery includes injecting a miscible injection fluid comprising an unfractionated hydrocarbon mixture through an injection well into a hydrocarbon bearing formation. Simultaneously and/or subsequently, a mobility control fluid is injected into the hydrocarbon bearing formation. Residual hydrocarbons in the hydrocarbon bearing formation are mobilized and displaced by the miscible injection fluid and/or the mobility control fluid to a production well through which they are produced to the surface.

Abstract: Y-grade NGL or L-grade is used as a carrier fluid to transport one or more chemical additives into a hydrocarbon bearing reservoir to treat the hydrocarbon bearing reservoir. The Y-grade NGL or L-grade and the chemical additives may be chilled and/or foamed.

Abstract: A method for enhanced or improved oil recovery includes injecting a miscible injection fluid comprising an unfractionated hydrocarbon mixture through an injection well into a hydrocarbon bearing reservoir at a structurally higher position to initiate gravity-stable displacement and gas cap expansion processes. Residual hydrocarbons in the hydrocarbon bearing reservoir are mobilized and displaced by the miscible injection fluid to a structurally lower position within the hydrocarbon bearing reservoir adjacent a production well through which they are produced to the surface.

Abstract: A method of treating a subsurface formation comprises mixing an unfractionated hydrocarbon mixture, water, and natural gas with a foaming agent to form a stimulation fluid comprising foam. The unfractionated hydrocarbon mixture comprises ethane, propane, butane, isobutane, and pentane plus. The method further includes increasing a pressure of the stimulation fluid and injecting the stimulation fluid into the subsurface formation.
