Abstract: Offshore systems and methods may be configured for offshore power generation and carbon dioxide injection for enhanced gas recovery for gas reservoirs. For example, a method may include: providing an offshore facility including a gas turbine, and a gas separator; producing a produced gas from a gas reservoir to the offshore facility; combusting the produced gas in a gas turbine to produce power and a flue gas; at least partially removing nitrogen from the flue gas in a gas separator to produce a carbon dioxide-enriched flue gas and a nitrogen-enriched flue gas; compressing the carbon dioxide-enriched flue gas in a gas compressor to produce a compressed gas; and injecting the compressed gas from the gas compressor into the gas reservoir, wherein 80 mol % or more of hydrocarbon in the produced gas is combusted and/or injected into the gas reservoir.

Abstract: Systems and methods are provided for improving product yields and/or product quality during co-processing of fast pyrolysis oil in a fluid catalytic cracking (FCC) reaction environment. The systems and methods can allow for co-processing of an increased amount of fast pyrolysis oil while reducing or minimizing coke production for a feedstock including fast pyrolysis oil and a conventional FCC feed. The reducing or minimizing of coke production can be achieved in part by adding a low molecular weight, non-ionic surfactant to the mixture of fast pyrolysis oil and conventional FCC feed.

Abstract: Systems and methods are provided for performing CO2 sorption and desorption using a sorbent structure with an integrated heat pump. The integrated heat pump can allow at least a portion of the heat generated during sorption to be recovered by forming steam from water. The steam raised during the sorption process can then be compressed and optionally heated to raise the temperature of the steam. The compressed and optionally heated steam can then be used as at least a portion of the steam for desorption of CO2 in the same sorbent bed or a different sorbent bed. By recovering the heat of sorption to raise steam, substantial energy savings can be achieved relative to a conventional process.

Abstract: Methods for electrohydraulic fracture stimulation of formations may include producing an acoustic shock wave having a compressive wave character in a wellbore penetrating a formation and manipulating the acoustic shock wave. The acoustic shock wave may be manipulated in one or more of the following steps: channeling the acoustic shock wave down the wellbore to change a shape of the acoustic shock wave to less spherical; converting the compressive wave character to an expansion wave character; and changing an acoustic impedance of the acoustic shock wave. The acoustic shock wave having the changed shape, the expansion wave character, and the changed acoustic impedance is distributed into the formation.

Abstract: Molten carbonate fuel cells (MCFCs) are operated to provide enhanced CO2 utilization. This can increase the effective amount of carbonate ion transport that is achieved. The enhanced CO2 utilization is enabled in part by operating an MCFC under conditions that cause transport of alternative ions across the electrolyte. The amount of alternative ion transport that occurs during enhanced CO2 utilization can be mitigated by using a more acidic electrolyte.

Abstract: Herein disclosed are methods and systems related to processes for injection wells generally utilized in the oil and gas industry. The methods herein include a method of estimating the relative cumulative volume of fluids injected into multiple zones of an injection well located in a hydrocarbon reservoir, the injection well including a plurality of zones. The method comprises injecting fluid into a wellbore of the injection well. The method further includes measuring temperature at points along the wellbore to produce a warm-back data set that includes data for a plurality of times and depths. The method also includes modifying an initial geotherm using only data from the warm-back data set that is in a middle-time region (MTR) of the warm-back data set to produce a calculated pseudo-geotherm. The calculated pseudo-geotherm may be used to estimate a volume of fluid injected into each of the plurality of zones.

Abstract: Methods for the in-situ application of coating agent to production tubing within wellbores using plunger lift systems are provided herein. One method includes shutting in the wellbore, pressurizing the production tubing to displace fluids from the production tubing, and dropping a plunger from the surface into the production tubing such that the plunger travels toward the bottom of the production tubing until landing on a bumper spring. The method also includes pumping a predetermined amount of the coating agent from the surface into the production tubing such that the coating agent flows to the bottom of the production tubing and settles on top of the plunger and utilizing the differential pressure between the production tubing and the annulus to return the plunger and the coating agent to the surface, where the coating agent is applied to the inner diameter of the production tubing as it flows toward the surface.
