Patent number: 10202829Abstract: A sand screen joint screens borehole fluid during production and bridges off loss control fluid during loss control. The joint has a basepipe having a bore and defining at least one elongated slot therein. Filter media is disposed on the basepipe and screens the borehole fluid. At least one flow device is disposed on the basepipe and restricts communication of the borehole fluid from the filter media to the at least one elongated slot. During the production, the at least one elongated slot communicates the borehole fluid from the at least one flow device to the bore. During the loss control, the at least one elongated slot bridges off with particulate from the loss control fluid communicated from the bore to the at least one flow device.Type: GrantFiled: November 21, 2014Date of Patent: February 12, 2019Assignee: WEATHERFORD TECHNOLOGY HOLDINGS, LLCInventor: Andrew McGeoch

Patent number: 9945211Abstract: A gravel pack assembly for a borehole has first and second joints and a foil. The basepipes of the joints connect end-to-end, and both of the basepipes having filters for filtering fluid passage from a borehole into bores of the basepipes. Transport tubes are disposed along the first and second joint, and a jumper tube expands across the connected ends of the basepipes and connects the transport tubes together. The foil encloses an area across the connected ends. The foil has an external surface defining an annulus thereabout with the borehole. The foil has end rings abutting the filters of the joints. At least a section of the foil leaks fluid from the borehole to the area enclosed by the foil, and at least a filter portion of the assembly filters the leaked fluid from the area to at least one of the first and second bores.Type: GrantFiled: January 22, 2015Date of Patent: April 17, 2018Assignee: Weatherford Technology Holdings, LLCInventors: Stephen McNamee, John S. Sladic, Stephen Reid, Andrew McGeoch, Matthew Manning, Daniel G. Purkis
