Publication number: 20240068340Abstract: A method comprises measuring a pressure at a plurality of times and a measured flow rate in a well. A measured productivity index (PI) is determined based, at least in part, on the measured flow rate and the pressure at the plurality of times. A flow rate at a second time is simulated, and a fluid pressure at the second time and a third time is simulated. A simulated PI is simulated based, at least in part, on the flow rate at the second time, and the fluid pressure at the second time and at the third time. An updated reservoir simulation model is generated by updating at least one parameter of the reservoir simulation model based, at least in part, on a difference between the measured PI and the simulated PI.Type: ApplicationFiled: August 26, 2022Publication date: February 29, 2024Applicant: SAUDI ARABIAN OIL COMPANYInventor: Babatope Kayode

Patent number: 11852011Abstract: Systems and methods include a computer-implemented method for generating a detailed heterogeneities map of a main reservoir. Pressure data for multiple wells of a main reservoir is received during a simultaneous field shut-in of the multiple wells. A scaled rate of change of pressure for each well is determined using the pressure data for each well. Rates of change of pressure for the multiple wells are plotted using the scaled rates of change of pressure. Clusters of wells having rates of change of pressure within a threshold difference of other wells in a given cluster are determined based on the plotting. A detailed heterogeneities map of the main reservoir is generated based the clusters of wells. The heterogeneities map defines heterogeneous regions. Each region contains a set of wells assigned to the heterogeneous region based on the wells having similar rates of change of pressure.Type: GrantFiled: October 11, 2021Date of Patent: December 26, 2023Assignee: Saudi Arabian Oil CompanyInventors: Babatope Kayode, Nora Hamidaddin

Publication number: 20220374571Abstract: Systems and methods include a computer-implemented method for predicting values. A numerical simulation model is generated based on observed production rates and flowing pressure and build-up (FPBU) test rates. A simulated diagnostic plot is generated using simulated FPBU data extracted from the numerical simulation model. Simulation model properties of the numerical simulation model are adjusted until the simulated diagnostic plot matches within a tolerance to an observed FPBU diagnostic plot. Predicted values including a static pressure, a water cut, and a gas-oil rate (GOR) are predicted using the simulated FPBU data. Observed data of a reservoir is reviewed and quality-checked based on comparing the predicted values within a tolerance of the observed data.Type: ApplicationFiled: May 21, 2021Publication date: November 24, 2022Inventor: Babatope Kayode
