Abstract: Methods to optimize solvent use in solvent-dominated processes for recovery of hydrocarbons are disclosed herein. In some embodiments, disclosed methods include injecting a solvent composition into a reservoir at a pressure above a liquid/vapor phase change of the solvent composition; injecting a chaser into the reservoir at a pressure above the liquid/vapor phase change of the solvent composition; allowing the solvent composition to mix with hydrocarbons in the reservoir and at least partially dissolve into the hydrocarbons to produce a solvent/hydrocarbon mixture; reducing the pressure in the reservoir below the liquid/vapor phase change pressure of the solvent composition thereby flowing at least a fraction of the solvent/hydrocarbon mixture from the reservoir; and repeating these steps as required.

Abstract: An internal combustion engine operates in a homogeneous-charge compression-ignition combustion mode. A method for controlling the internal combustion engine in response to a fast transient event from a low-load state to a high-load state includes operating the engine with a negative valve overlap between an intake valve and an exhaust valve, and determining a preferred combustion phasing responsive to the high-load state. A preferred EGR mass and a preferred intake valve timing corresponding to the preferred combustion phasing are determined. A first intake valve timing is determined in response to a difference between the preferred EGR mass and an actual EGR mass. The intake valve timing is controlled in response to a difference between the preferred intake valve timing and the first intake valve timing.

Abstract: Systems and methods for controlling in situ resistive heating elements may be utilized to enhance hydrocarbon production within a subterranean formation. An in situ resistive heating element may be controlled by heating a controlled region associated with the in situ resistive heating element, injecting a control gas into the controlled region, and adjusting the electrical conductivity of the controlled region with the control gas. The controlled region may be located such that the heating and injecting may change the shape of the in situ resistive heating element and/or guide the in situ resistive heating element towards subterranean regions of potentially higher productivity and/or of higher organic matter.
