METHODS AND SYSTEMS FOR MONITORING NEAR-WELLBORE AND FAR-FIELD RESERVOIR PROPERTIES USING FORMATION-EMBEDDED PRESSURE SENSORS

摘要

A method for measuring formation property includes obtaining a set of measurements indicative of wellbore pressures for a selected duration after a pressure perturbation is created in a wellbore; obtaining at least one additional set of measurements indicative of formation pressures for the selected duration after the pressure perturbation; and deriving the formation property based on the set of measurements indicative of the wellbore pressures and the at least one additional set of measurements indicative of formation pressures. A system for measuring formation property includes a first pressure sensor disposed proximate a wellbore for measuring pressures in the wellbore; a second pressure sensor disposed in a formation at a predetermined distance from the wellbore; and a flow rate measuring device.
