Wellbore method and apparatus for sand and inflow control during well operations
Abstract:
Method and apparatus for producing hydrocarbons including a wellbore that accesses a subsurface reservoir; a production tubing string disposed within the wellbore; and sand control devices coupled to the production tubing string. At least one of the sand control devices includes a first tubular member having a permeable section and a non permeable section; a second tubular member disposed within the first tubular member. The second tubular member has a plurality of openings and an inflow control device that provides a flow path to the interior. The sand control devices include a sealing mechanism disposed between the first tubular member and the second tubular member to provide pressure loss during gravel packing operations that is less than the pressure loss during production operations.
