Abstract
Official abstract text for this publication.
A sand control tool including a base pipe having a radial port through a wall thereof, a plurality of volume increasing members disposed upon the base pipe, a filtration segment disposed upon the base pipe and disposed between and in physical contact with ones of the plurality of members, and a cover disposed radially outwardly upon the plurality of members and plurality of segments. An embodiment of a sand control tool including a base pipe having a radial port through a wall thereof, a volume increasing member helically disposed upon the base pipe, a filtration segment helically disposed upon the base pipe adjacent the member, and a cover disposed radially outwardly upon the member and segment.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for controlling sand in a borehole comprising: running a tool comprising a base pipe having a radial port through a wall thereof; a plurality of volume increasing members disposed upon the base pipe; a filtration segment disposed upon the base pipe and disposed between and in direct physical contact with ones of the plurality of members; and a cover disposed radially outwardly upon the plurality of members and the filtration segment into the borehole; allowing the plurality of members to volumetrically increase; and conforming the tool to the borehole. 2. The method as claimed in claim 1 , including expanding the cover and passing fluid through the cover. 3. The method as claimed in claim 1 , including degrading the cover. 4. The method as claimed in claim 1 wherein the plurality of volume increasing members are at least 3 members and the filtration segment is at least two segments ones of at least two segments being interposed between each of the at least three members. 5. The method as claimed in claim 1 wherein the plurality of volume increasing members compress the segment therebetween, causing the segment to extend radially into conformance with the borehole. 6. The method as claimed in claim 1 wherein the plurality of volume increasing members are annularly shaped. 7. The method as claimed in claim 1 , wherein the plurality of volume increasing members have a thickness longitudinally along the tool that ranges from about 2:1 to about 5:1 of a longitudinal thickness of the segment. 8. The method as claimed in claim 1 , wherein the filtration segment includes one or more of an inorganic pack material, a particulate based filter, a polymer gravel pack material, and a nutshell pack material. 9. The method as claimed in claim 1 , wherein the filtration segment is a shape memory material. 10. The method as claimed in claim 1 , wherein the cover includes radially directed holes. 11. The method as claimed in claim 1 , wherein the cover is an elastomer. 12. The method as claimed in claim 1 further including producing fluid through the tool.
