Patent number: 9027640Abstract: A method and apparatus for controlling the operation of a well involves locating a pressure monitoring device downhole and arranging it to be operative: to monitor a characteristic pressure profile of a well during a certain time span controlled by a downhole clock associated with the device; to monitor the temperature downhole in the region of the clock; to calibrate a time reading of the downhole clock with reference to the monitored temperature to correct for drift between the clock time and real time resulting from the downhole elevated temperature; and to respond and generate a triggering output when a significant deviation to the pressure profile is introduced into the well as a control signal to the monitoring device, by comparing two separate pressure profiles within the time span, the device only generating the triggering output when the same pressure profile is monitored twice within the time span.Type: GrantFiled: March 21, 2013Date of Patent: May 12, 2015Assignee: Omega Completion Technology Ltd.Inventors: Mark Buyers, David Forsyth

Patent number: 8544542Abstract: A method and apparatus for controlling the operation of a well which is not flowing or in which fluid is pumped or injected into the well utilising a downhole located pressure monitoring device which is operative to monitor a characteristic pressure profile of the well, and to respond and generate a triggering output when a significant deviation to the pressure profile is introduced into the well as a control signal to the monitoring device by comparing two separate pressure profiles within a certain time span, the device only generating a triggering output when the same pressure profile is monitored twice within the time span; and an actuator which is initiated into operation to control any required operation of the well when the monitoring device responds to the control signal and generates the triggering output.Type: GrantFiled: December 14, 2009Date of Patent: October 1, 2013Assignee: Omega Completion Technology Ltd.Inventors: Mark Buyers, David Forsyth
