a sand control completion that uses a screen and a gravel pack to stop formation sand production.

expandable sand control screen.

a sand control technique coupling fracture treating (usually a tip screenout fracture) with a screen and gravel packing of the wellbore.

n: a mass of very fine gravel placed around a slotted liner in a wen. See gravel packing.

n: A sand-control method used to prevent production of formation sand. In gravel pack operations, a steel screen is placed in the wellbore and the surrounding annulus packed with prepared gravel of a specific size designed to prevent the passage of formation

a sand control completion that uses a larger gravel to stop the formation sand and a screen to stop the gravel.

a sand control operation in which gravel is injected into a well where a screen has been placed. The pressure of the injection is usually at or near the fracture pressure of the reservoir and a pressure packing of all perforations ensues. Some perf breakd

a perforated, drilled or slotted liner for formation control or to preserve wellbore access.

a sand control screen made from steel wool trapped between two perforated or slotted liners.

n: naked section of oil layer is filled with gravel and evenly distribution, which prevent inrush of sand.


a sand control completion for high permeability soft sand formations where the small amount of area offered by the perforations is a restriction on what the formation can deliver to the wellbore.

n: a liner that has had holes shot in it by a perforating gun. See liner.

n: the liner in which the hole have been made before it assembled and run in the wellbore, it provides the channel for the oil flow.

a liner with holes drilled for fluid entry. Not usually for sand control but may be useful for increasing hole stability or access.

a sand control screen that uses a captured gravel or resin coated gravel to assist in restraining formation sand or gravel packing gravel.
