A shaker assembly and method, of which the shaker assembly includes a shaker tank, a mixing tank in fluid communication with the shaker tank and positioned adjacent thereto, an overflow weir positioned between and separating the shaker tank and the mixing tank, a first shaker positioned over the shaker tank, and a second shaker. The first and second shakers are configured to operate in parallel to partially separate a solid from a liquid of a drilling waste fluid. During normal operation, at least some of the liquid flows from the first and second shakers to the shaker tank, and from the shaker tank over the overflow weir and into the mixing tank.

A power generation assembly and related methods to enhance power efficiency and reduce greenhouse gas emissions associated with a power-dependent operation, may include a gas turbine engine. The power generation assembly also may include a heat exchanger positioned to receive exhaust gas from the gas turbine engine during operation. The heat exchanger may include an exhaust gas inlet positioned to receive exhaust gas and a liquid inlet positioned to receive liquid. The heat exchanger may be positioned to convert liquid into steam via heat from the exhaust gas. The power generation assembly further may include a steam turbine positioned to receive steam from the heat exchanger and convert energy from the steam into mechanical power. The power generation assembly still further may include an electric power generation device connected to the steam turbine and positioned to convert the mechanical power from the steam turbine into electrical power.

This invention relates to a method and a system for abating hydrogen sulfide (H.sub.2S) and carbon dioxide (CO.sub.2) from H.sub.2S and CO.sub.2rich gas mixtures such as geothermal non-condensable gas mixtures (NCG). The H.sub.2S and CO.sub.2 gas is separated from the remaining gases contained in the H.sub.2S and CO.sub.2rich gas mixtures by pressurizing the gas stream and feeding it into an absorption column where H.sub.2S and CO.sub.2 are preferentially dissolved in a water stream, resulting in water stream rich in H.sub.2S and CO.sub.2. The H.sub.2S and CO.sub.2 rich water stream may then be re-injected into a geological reservoir or used for pH modification of another water stream of geological origin.

A method for managing a sequestration fluid including sequestering a fluid in a subsurface formation downhole of a caprock and downhole of a seal in a borehole, targeting a sample of formation fluid in the borehole uphole of the caprock and uphole of the seal in the borehole. A sequestration system including a borehole in a formation, the borehole extending downhole of a caprock, a string disposed in the borehole, a seal between the string and a wall of the borehole uphole of the caprock, and a port in the string uphole of the seal and the caprock, the port having access to a portion of the formation uphole of the caprock.

A method for operating a kerogen-rich unconventional gas reservoir characterized by there being multiple hydraulically-fractured wells drilled thereinto comprises: recovering a methane-containing gas from a first hydraulically-fractured well drilled into the gas reservoir, steam-methane reforming the recovered methane-containing gas to yield a hydrogen gas and an inorganic carbon-containing gas, injecting at least a portion of the hydrogen gas into a second hydraulically-fractured well drilled into the gas reservoir, and injecting at least a portion of the inorganic carbon-containing gas into a third hydraulically-fractured well drilled into the gas reservoir.

To control hydrostatic backpressure of disposal wells connected to a disposal plant surface network, density of water to be injected from a water disposal plant system into disposal wells formed in a subterranean zone, a density of a hydrostatic backpressure-modifying additive to modify a density of the water, a target total injection flow rate of the water, and a vertical depth of a portion of the subterranean zone through which the water is to be injected are identified. Injected water flow rate upstream of an injection point into the multiple disposal wells, wellhead injection pressure needed to achieve the target total injection flow rate and a total injection rate are periodically received. Based on these parameters, dosage rate of the additive to maintain the target total injection flow rate is periodically determined. An additive quantity is injected into the water and periodically modified based on the periodically determined dosage rate.

The present invention discloses a multi-energy complementary system for a co-associated abandoned mine and a use method. The multi-energy complementary system for a co-associated abandoned mine includes a mining mechanism, a grouting mechanism and an energy mechanism. In the present invention, the mining of coal and uranium resources is realized through the mining mechanism, the subsidence and seepage reduction of the stratum is realized through the grouting mechanism, and the effective utilization of waste resources is realized through the energy mechanism. Finally, with the efficient cooperation of the three mechanisms, safe and efficient development and utilization of co-associated resources in the full life cycle are realized, and the purposes of green and efficient mining of coal and uranium resources and secondary development of a coal seam goaf are achieved, thereby facilitating the realization of dual-carbon goals and the development of low-carbon green energy.

Systems and methods for monitoring and managing day to day performance of a group of salt water disposal wells in a network include performing operations including performing a well measurement to generate salt-water disposal (SWD) well data; retrieving a machine learning model that is trained using labeled SWD data, the labeled SWD data representing one or more SWD well faults causing respective data signatures in the SWD data, each respective data signature being associated with a corresponding label identifying the SWD well fault for a particular SWD well; inputting the SWD well data generated in real-time based on SWD well operation, into the machine learning model; generating, by the machine learning model based on the inputting, a classification output representing a predicted well injection pressure or injection rate of the particular SWD well including SWD wells faults/anomalies; and generating, based on the classification output, control data for changing operation of the particular SWD well.

Steel and/or copper spherical capsules are specifically engineered and manufactured for housing uranium waste products. The uranium waste products are placed within the spherical capsules. Human-made cavern(s) and/or substantially lateral wellbore(s) are constructed for receiving the uranium waste containing spherical capsules. The human-made cavern(s) and/or the substantially lateral wellbore(s) are deeply located in specific types of geologic rock formations thousands of feet below the Earth's surface. These uranium waste containing spherical capsules are loaded from the Earth's surface into the human-made cavern(s) and/or into the substantially lateral wellbore(s). The emplaced spherical capsules are surrounded by an immersive protective medium within the given human-made cavern(s) and/or within the substantially lateral wellbore(s). The given human-made cavern(s) and/or the given substantially lateral wellbore(s), with the uranium waste containing spherical capsules, are sealed off.
