  • Method for determining parameters of a bottomhole and a near-bottomhole zone of a wellbore
    Patent number: 9556724
    Abstract: Whiles moving a pipe string in a wellbore during tripping operations, pressure and temperature are measured. Based on the measured pressure and temperature, such parameters of a bottomhole and a near-bottomhole zone of the wellbore are calculated as skin factor, permeability, reservoir thickness, bottomhole pressure, and outflow or inflow from/to the zone under consideration.
    Type: Grant
    Filed: December 17, 2013
    Date of Patent: January 31, 2017
    Assignee: SCHLUMBERGER TECHNOLOGY CORPORATION
