  • Formation isolation valve and method of use
    Patent number: 7617876
    Abstract: The present invention provides for high volume flow from a well. A retrievable formation isolation valve allows high volume flow through the remaining casing or tubing. Alternatively, a large bore valve configuration that is not retrieved, but remains as part of the casing, can be used. The present invention also includes methods to allow for high volume flow using retrievable isolation valves or large bore valves.
    Type: Grant
    Filed: February 19, 2008
    Date of Patent: November 17, 2009
    Assignee: Schlumberger Technology Corporation

  • Complete trip system
    Patent number: 6745834
    Abstract: The present invention discloses apparatus and methods for perforating, completing, testing, and abandoning a wellbore in a single trip. One embodiment of the invention is a method that comprises perforating an interval within the wellbore, positioning a sand screen assembly adjacent the perforated interval, gravel packing the perforated interval, performing testing on the perforated interval, and then abandoning the well, all in a single trip in the wellbore.
