The orientation of the at least one tunnel ensures that the network of fractures extends through a target zone in a hydrocarbon bearing region of the formation. | 2021-05-06 |
| 20210131243 | Oil Recovery Method - A method for recovering crude oil from a reservoir including at least one layer of reservoir rock having crude oil and a formation water within the pore space thereof includes injecting into the layer(s) of reservoir rock from an injection well, alternating slugs of an aqueous displacement fluid comprising a concentrated solution of a water-soluble additive in an aqueous solvent and of an aqueous spacer fluid. The number of injected slugs of aqueous displacement fluid, n, is in the range of 15 to 1000 per swept pore volume, PVR, of the layer(s) of reservoir rock. The injected pore volume of each individual slug, PV | 2021-05-06 |
| 20210131244 | SUPER HEAVY OIL DEVELOPMENT METHOD FOR STRENGTHENING SAGD STEAM CHAMBER TO BREAK THROUGH LOW PHYSICAL PROPERTY RESERVOIR - Disclosed belongs to the technical field of oil and gas field development engineering, and particularly relates to a super heavy oil development method for strengthening an SAGD steam chamber to break through a low physical property reservoir. The super heavy oil development method for strengthening the SAGD steam chamber to break through the low physical property reservoir includes the following steps: (1) selection of a developed oil reservoir; (2) well distribution; (3) steam chamber forming; (4) steam chamber expansion; (5) steam chamber strengthening. The method may enhance the ability of the steam chamber to break through the low physical property reservoir, enlarge the development height of the steam chamber, and further improve the SAGD development effect of super heavy oil. | 2021-05-06 |
| 20210131245 | MICROBIALLY ENHANCED THERMAL OIL RECOVERY - A method and a system for recovering oil from currently inaccessible oil containing geological units by activating the deep biosphere microbial seed bank. Nutrient and thermal enhancement of microorganisms in oil containing geological units allows for stimulation of inactive and/or dormant microorganisms such that they proliferate and produce gas. The oil viscosity that is decreased by heat, along with the gas pressure produced by activated microbes which allows previously inaccessible oil to flow toward production wells. | 2021-05-06 |
| 20210131246 | METHODS TO PERFORM WELLBORE STRENGTHENING, METHODS TO PULSE HYDRAULIC FRACTURE A DOWNHOLE FORMATION, AND WELLBORE STRENGTHENING SYSTEMS - Methods to perform wellbore strengthening, methods to pulse hydraulic fracture a downhole formation, and wellbore strengthening systems are disclosed. A method to perform wellbore strengthening includes deploying an annular isolation device in a wellbore of a well. The method also includes pumping a fluid carrying a loss circulation material through a conveyance into a zone of an annular region of a wellbore. The method further includes activating the annular isolation device to reduce fluid flow in the zone. The method further includes generating a hydraulic pulse to form one or more fractures. The method further includes injecting a loss circulation material into the one or more fractures. | 2021-05-06 |
