Patent number: 11308409Abstract: A method for quantifying frac hits within a few days using a novel pressure-transient analysis technique called differential pressure-transient analysis (DPTA). Unlike pressure transient analysis (PTA) methods, focused on single-well analyses, DPTA evaluates pressure response from two or more wells simultaneously to (1) determine the existence of frac hits, and (2) determine the degree of interference, defined as the ratio of inter-connected to total number of primary fractures from a given well. The output from (2) can be subsequently used to accurately predict oil and/or gas production rates for infill and offset wells.Type: GrantFiled: February 12, 2020Date of Patent: April 19, 2022Assignee: ENOVATE CORP.Inventor: Oscar Mauricio Molina Ortiz

Patent number: 11126762Abstract: A data processing system is provided which determines the migration of oil and gas by a basin simulation section and predicts future reservoir performance from current reservoir production measures. The data processing system provides more accurate reservoir rock and fluid property distribution in reservoir locations between well locations where such attributes cannot be measured. The data processing system operates based on physical realities captured from migration by the basin simulation section. The data processing system differs from conventional methods, which use measurements obtained at the wells and interpolate between for regions between the wells using statistical techniques. Results from the data processing system shed more light into reservoir discontinuities among the wells, and yield better distribution of hydrogen sulfide, tar zones (Heavy Oil) within the reservoir.Type: GrantFiled: February 28, 2018Date of Patent: September 21, 2021Assignee: Saudi Arabian Oil CompanyInventor: Ali Haydar Dogru

Patent number: 11098582Abstract: Earth models of stress conditions in subsurface reservoirs are formed reflecting rock mechanical properties, stress regime and also wellbore stability. A number of variables related to the rock mechanical properties and stress conditions are parameterized. The variability of minimum horizontal stress magnitudes as a product of the relative contributions of the various rock properties and input parameters or variables used to form the model is analyzed. Differences between predicted minimum horizontal stress magnitudes in the formation and an actual measurement obtained from the formation (for example, fracture closure pressure) are determined. The determined differences are the minimized through an optimization methodology to find a best set of parameters suitable to match the minimum horizontal stress to actual formation measurement.Type: GrantFiled: February 17, 2020Date of Patent: August 24, 2021Assignee: Saudi Arabian Oil CompanyInventors: Otto E Meza Camargo, Tariq Mahmood
