Abstract: A method of enhanced oil recovery from an unconventional resource reservoir comprises injecting an enhanced recovery fluid into the unconventional resource reservoir via an injection well and producing hydrocarbons from the unconventional resource reservoir via the injection well or a production well offset from the injection well.

Abstract: An in-line L-Grade recovery system having a first in-line separator in communication with a natural gas stream and configured to separate the natural gas stream into a gas stream and a liquid stream, a second in-line separator in communication with the first in-line separator and configured to separate the liquid stream into L-Grade and water, and a storage tank in communication with the second in-line separator and configured to store the L-Grade.

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 of treating a subsurface formation comprises mixing an unfractionated hydrocarbon mixture with a foaming agent to form a waterless 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.

Abstract: A prong is configured for use with a concrete reinforcement element and includes first and second legs positioned opposite first and second sides of the prong and a bridge portion connecting distal ends the legs, where the bridge portion forms a first end of the prong. The legs extend from the bridge portion to a second end of the prong opposite the first end, and each of the legs has a proximal end at the second end of the prong. The proximal end of the first leg is bent toward the second leg, and the proximal end of the second leg is bent toward the first leg, such that the proximal ends of the legs overlap each other. Inner surfaces of the proximal ends of the legs define engagement surfaces configured to engage a tie wire, enabling the proximal ends to be connected to the tie wire.
