Abstract

Abstract An unconsolidated subterranean zone (12) penetrated by a wellbore (10) is completed by placing a slotted liner (20) having an internal sand screen (35) disposed therein in the zone, isolating the slotted liner (20) and the wellbore (10) in the zone (12) and injecting particulate material into the annuli between the sand screen and the slotted liner an the slotted liner and the wellbore to thereby form packs of particulate material therein to prevent the migration of fines and sand with produced fluids. <IMAGE>

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 145 words
A method of completing an unconsolidated subterranean zone penetrated by a wellbore, which method comprises the steps of: (a) placing in said zone a slotted liner having an internal sand screen disposed therein whereby a first annulus is formed between said sand screen and said slotted liner and a second annulus is formed between said slotted liner and said wellbore; (b) isolating said second annulus between said slotted liner and said wellbore in said zone; and (c) injecting particulate material into said first annulus between said sand screen and said slotted liner and into said second annulus between said slotted liner and said wellbore by way of the slots in said slotted liner, whereby said particulate material is uniformly packed in said first and second annuli and the migration of formation fines and sand with fluids produced into said wellbore from said zone is prevented.
Claim 2
Dependent Claim 12 words
A method according to claim 1, wherein said particulate material is sand.
Claim 3
Dependent Claim 17 words
A method according to claim 1 or 2, wherein said wellbore in said subterranean zone is open-hole.
Claim 4
Dependent Claim 28 words
A method according to claim 1, 2 or 3, wherein said wellbore in said subterranean zone has casing cemented therein with perforations formed through the casing and cement.
Claim 5
Dependent Claim 27 words
A method according to claim 1, 2, 3 or 4, wherein said annulus is isolated in accordance with step (b) by setting a packer in said wellbore.
Claim 6
Independent Claim 33 words
A method according to any of claims 1 to 5, which further comprises the step of creating at least one fracture in said subterranean zone prior to or while carrying out step (c).
Claim 7
Dependent Claim 18 words
A method according to claim 6, which further comprises the step of depositing particulate material in said fracture.
