  • Downhole surge pressure reduction and filtering apparatus
    Patent number: 7487831
    Abstract: The present invention provides a downhole cementing apparatus run into a borehole on a tubular. The apparatus is constructed on the pipe in such a way that pressure surge during run-in is reduced by allowing fluid to enter the pipe and utilize the fluid pathway of the cement. In one aspect of the invention, an inner member is provided that filters fluid as it enters the fluid pathway. In another aspect of the invention, various methods are provided within the cementing apparatus to loosen and displace sediment in the borehole prior to cementing.
    Type: Grant
    Filed: July 16, 2007
    Date of Patent: February 10, 2009
    Assignee: Weatherford/Lamb, Inc.
