Embodiment Construction

[0031] Certain aspects and embodiments of the present invention relate to screen assemblies capable of being disposed in a perforation (eg, a wellbore) of a formation for producing hydrocarbon fluids from the formation. The screen assembly can be configured to support the conduit and reduce or eliminate clogging of the conduit by the expandable material. Screen assemblies according to some embodiments include a support material positioned between the conduit and the expandable material external to the base pipe. The conduit may include a plurality of perforations and may receive and direct hydrocarbon fluids from the formation. The expandable material is capable of expanding upon contact with the activating fluid and displacing the surface of the catheter towards the bore. The expandable material is capable of expanding to a greater extent than the support material, and the support material can reduce or prevent blockage of the perforation caused by expansion of the expandabl...

Abstract

The present invention describes an expandable screen assembly, specifically a screen assembly capable of being disposed in a wellbore for hydrocarbon fluid production. The screen assemblies can support tubes for receiving hydrocarbon fluid and reduce or eliminate plugging of the tubes by swellable material. A screen assembly may include a support material between a tube and swellable material located exterior to a base pipe. The tube may include perforations and can receive and direct hydrocarbon fluids from the formation. The swellable material can expand after contact with an activating fluid and can displace the tube toward a surface of the bore. The swellable material can expand more than the support material and the support material can reduce or prevent plugging of the perforations by the swellable material expanding.

Description

technical field [0001] The present invention relates generally to control screens for subsurface fluid production, and more particularly (though not necessarily exclusively) to a swellable screen assembly having Support material for catheters. Background technique [0002] Hydrocarbons may be produced by wellbores penetrating the formation. In some cases, the formation may be unconsolidated or loosely consolidated. Particulate matter such as sand from such formations may be produced along with hydrocarbons. The output of particulate matter can cause many problems. These problems include, for example, production of particulate matter at the surface, causing wear of components in the production assembly, partially or completely clogging the production interval, and causing damage to the production assembly by collapsing onto some or all of the production assembly. damage. [0003] Expandable control screens, such as sand control screens, may be used to provide stability t...
