Patent number: 11603746Abstract: A physical modeling method that includes providing a reservoir core plug, the reservoir core plug having a wellbore interface end, an outlet interface end, and a cylindrical face and saturating the reservoir core plug with hydrocarbon and brine to form a saturated core plug. The method also includes positioning the saturated core plug within a flooding apparatus and pumping the fracturing fluid through saturated core plug to displace a portion of the hydrocarbon to form a displaced hydrocarbon plug. In addition the method includes positioning the displaced hydrocarbon plug in an imbibition cell and conducting an imbibition test to form an imbibed core plug having brine and hydrocarbon. Further the method includes positioning the imbibed core plug in core-flooding apparatus and displacing a portion of the brine and hydrocarbon from the imbibed core plug.Type: GrantFiled: April 12, 2021Date of Patent: March 14, 2023Assignee: ALCHEMY SCIENCES, INC.Inventor: Luchao Jin

Patent number: 11486871Abstract: A method includes determining reservoir rock and fluid characteristics of a reservoir rock and, based on the reservoir rock and fluid characteristics of the reservoir rock, selecting a core. The method also includes selecting a first surfactant and selecting a second surfactant. In addition, the method includes performing a water block mitigation test using the selected core, the first surfactant and the second surfactant and performing a proppant phase trapping mitigation test using the selected core, the first surfactant and the second surfactant.Type: GrantFiled: September 15, 2020Date of Patent: November 1, 2022Assignee: ALCHEMY SCIENCES, INC.Inventors: Luchao Jin, Shashidhar Rajagopalan, James Russum

Patent number: 11236265Abstract: A fluid injection process includes removing a core sample from a low permeability reservoir. The process also includes performing an imbibition test on a plurality of stage one surfactants, each stage one surfactant mixed with a first treatment fluid and using a portion of the core sample to obtain a wettability index or measurement of capillary pressure. The process includes selecting a stage one surfactant and performing an oil recovery test on a plurality of stage two surfactants, each stage two surfactant mixed with a second treatment fluid. The process includes selecting a stage two surfactant and injecting the selected stage one surfactant into a matrix of the low permeability reservoir. In addition, the method includes injecting the selected stage two surfactant into a fracture network of the low permeability reservoir.Type: GrantFiled: September 21, 2020Date of Patent: February 1, 2022Assignee: ALCHEMY SCIENCES, INC.Inventors: Luchao Jin, James Russum

Patent number: 10815416Abstract: A fluid injection process includes removing a core sample from a low permeability reservoir. The process also includes performing an imbibition test on a plurality of stage one surfactants, each stage one surfactant mixed with a first treatment fluid, using a portion of the core sample to obtain a wettability index or measurement of capillary pressure for each stage one surfactant. In addition, the process includes selecting a stage one surfactant by determining which of the plurality of stage one surfactants has the highest wettability index or lowest capillary pressure and performing an oil recovery test on a plurality of stage two surfactants, each stage two surfactant mixed with a second treatment fluid. Further, the process includes selecting a stage two surfactant by determining which of the plurality of stage two surfactants has the highest oil recovery test result and injecting the selected stage one surfactant into a matrix of the low permeability reservoir.Type: GrantFiled: April 9, 2019Date of Patent: October 27, 2020Assignee: ALCHEMY SCIENCES, INC.Inventors: Luchao Jin, James Russum
