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.
Claims20
A method of injecting a treatment fluid into a hydrocarbon bearing reservoir, comprising:
- mixing an unfractionated hydrocarbon liquid mixture and a chemical additive, wherein the unfractionated hydrocarbon liquid mixture is a by-product of a de-methanized hydrocarbon stream and comprises ethane, propane, butane, isobutane, pentane, and less than one percent methane by liquid volume, wherein the unfractionated hydrocarbon liquid mixture is sourced and transported from a separate processing facility that is located at a location remote from the hydrocarbon bearing reservoir, wherein the separate processing facility comprises at least one of a splitter facility, a gas plant, and a refinery, wherein the unfractionated hydrocarbon liquid mixture is transported via pressure storage vessels from the separate processing facility to the hydrocarbon bearing reservoir;
- pressurizing the unfractionated hydrocarbon liquid mixture and the chemical additive with a first pump;
- pressurizing a liquefied gas with a second pump;
- vaporizing the liquefied gas with a vaporizer;
- mixing the pressurized, vaporized gas with the pressurized, unfractionated hydrocarbon liquid mixture and chemical additive to form a treatment fluid;
- and
- pumping the treatment fluid into the hydrocarbon bearing reservoir at a pressure greater than a formation pressure of the hydrocarbon bearing reservoir.
