OILFIELD DEEP WELL PROCESSING AND INJECTION FACILITY AND METHODS

Systems and methods for processing one or more waste fluids by measuring one or more properties of a waste fluid and adjusting the flow and/or flowability of the waste fluid based on the measurement are disclosed. The one or more properties of the waste fluid can include a viscosity of the waste fluid, a pressure of the waste fluid, and/or or a difference in pressure of the waste fluid. Adjusting the flow and/or flowability of the waste fluid can include adjusting the one or more properties of the waste fluid and/or affecting the direction of flow of the waste fluid in a manner which changes the destination of the waste fluid.

METHOD FOR DETECTING GAS-STORING PERFORMANCE OF SOLUTION-MINED SALT CAVERN IN HIGH-INSOLUBLE SALT MINE
20220099519 · 2022-03-31 ·

The present disclosure discloses a method for detecting gas-storing performance of solution-mined salt cavern in a high-insoluble salt mine, comprising: detecting water-tightness of the cavern and water-tightness of a wellbore; arranging a gas sealing tubing in a production casing for the wellbore, and arranging a packer; detecting gas-tightness of the wellbore; injecting test gas into the cavern through the gas sealing tubing at a gas-injection well; calculating a volume of a discharged brine; closing the debrining well, and injecting the test gas into the cavern through the gas sealing tubing at the gas-injection well; after a pressure value above a gas-liquid interface in the cavern reaches a set pressure value, closing the gas-injection well; and detecting gas-tightness of the cavern. The method can be used for effectively, accurately and economically detecting the available gas storing space volume and the gas-tightness of the solution-mined salt cavern in salt mine.

Slurrification and disposal of waste by pressure pumping into a subsurface formation

A computerized method for management of a slurry injection well and the associated surface facility. The method utilizes real time and historical data of injection and slurry parameters in conjunction with computer simulations on a computer-modelled reservoir to predict well behavior during one or a series of injection events. The system determines optimized injection operation schedules, recommends and implements changes to an injection operation, including while in process such as through automated equipment control.

Emergency method and system for in-situ disposal and containment of nuclear material at nuclear power facility

A system and method to safely isolate mobile radioactive material during an emergency includes a borehole located in close proximity and at a depth sufficient to safely isolate the material and a man-made vertical-oriented gravity fracture located at the bottom end of the borehole. During an emergency, the mobile radioactive material enters the borehole and then passes from there into the gravity fracture. The mobile radioactive material may have sufficient density to further propagate the fracture vertically downward or a dense slurry or fluid could be mixed with the mobile radioactive material.

SYSTEM FOR FRICTION REDUCTION USING NANO-BUBBLES
20220065076 · 2022-03-03 ·

An automated produced water treatment system that injects ozone or an ozone-oxygen mixture upstream of produced water separators, with the dose rate changing dynamically as the produced water quality changes, as determined by continuous monitoring of the produced water quality by a plurality of sensors that detect water quality parameters in real time. The system may operate as a “slipstream” injection system, that draws a portion of produced water from the produced water pipeline and injects ozone or an ozone-oxygen mixture back into the pipeline with disrupting or slowing normal operations. Disinfectants or other additives may also be injected. The treatment system may be wholly or partially contained in mobile containers or trailers, for on-the-fly use in existing produced water treatment facilities. Ozone and/or nitrogen micro-bubbles and/or nano-bubbles may be introduced for friction reduction in oil and gas operations.

METHOD AND SYSTEM FOR REMOVING CARBON DIOXIDE

The method and system for removing CO.sub.2 from the atmosphere or the ocean having the steps of, feeding a solid oxide fuel cell (SOFC) system with a gaseous hydrocarbon feed, converting the gaseous hydrocarbon feed in the SOFC system into an anode exhaust stream having carbon dioxide CO.sub.2, the SOFC system thereby producing electricity; injecting the anode exhaust stream as an injection gas into an underground coal bed; in the underground coal bed the injection gas causing coal bed methane (CBM) to desorb from the coal and CO.sub.2 to adsorb onto the coal; extracting the coal bed methane (CBM) from the underground coal bed; and discharging a production gas having the coal bed methane (CBM) from the underground coal bed.

Optimizing waste slurry disposal in fractured injection operations

Methods and apparatus are provided for optimizing operations for a fracturing injection waste disposal well especially where the formation is damaged or tight such that pressure fall-off tests are impractical due to extended leak-off rate times. Formation closure pressure and formation stress are calculated using Instantaneous Shut-in Pressure rather than traditional methods requiring actual fracture closure.

HYDROFRACTURING APPLICATIONS UTILIZING DRILLING CUTTINGS FOR ENHANCEMENT OF WELLBORE PERMEABILITY

The present disclosure provides methods and systems for hydrofracturing processes utilizing native drilling cuttings to enhance wellbore permeability. The native drilling cuttings are obtained during drilling operations and may be used in hydrofracturing applications without further grinding or processing. The native drilling cuttings can be combined into a slurry and injected into a well for the hydrofracturing application. In some cases, the native drilling cuttings are dried before combining them with the slurry.

Protection of Structures with Subterranean Injection of Lignocellulosic Solids
20210324258 · 2021-10-21 ·

A method for altering a characteristic of the ground. The method comprises the steps of preparing a lignocellulosic material, suspending the lignocellulosic material in a slurry to create a lignocellulosic slurry, and creating a fluid movement of the lignocellulosic slurry. The method further includes the steps of resuspending a portion of the lignocellulosic slurry with the fluid movement; and injecting the lignocellulosic slurry below the surface of the ground.
