Abstract
A tubular for reservoir fines control includes a body having an outer surface and an inner surface defining a flow path. A plurality of openings are formed in the body connecting the outer surface and the flow path. A material mesh is overlaid onto the outer surface. The material mesh is formed from a material swellable upon exposure to a selected fluid. The material mesh has a selected porosity allowing methane to pass into the flow path while preventing passage of fines.
Claims16
A tubular for reservoir fines control comprising:
- a body including an outer surface and an inner surface defining a flow path, a plurality of openings are formed in the body connecting the outer surface and the flow path;
- and
- a material mesh extending along in contact with the outer surface, the material mesh being formed from a material swellable upon exposure to a selected fluid, the material mesh having a selected porosity allowing methane to pass into the flow path while preventing passage of fines, wherein the material mesh includes a first material mesh layer including a plurality of cord members extending axially along in contact with the outer surface and a second material mesh layer overlaid onto the first material mesh layer, each of the first material mesh layer and the second material mesh layer being expandable.
A method of forming a permeable cover on a perforated tubular comprising:
- positioning a material mesh permeable to a downhole fluid on and in contact with an outer surface of the perforated tubular, the material mesh comprising a first material mesh layer including a plurality of cord members extending axially along in contact with the outer surface and a second material mesh layer overlaid onto the first material mesh layer, each of the first material mesh layer and the second material mesh layer being expandable.
