Abstract: A system and method for producing hydrocarbons from a well with a dual sleeve valve assembly. The dual sleeve valve assembly has a toe valve assembly and a production assembly. The toe valve assembly has a valve sleeve positioned in a valve housing comprising at least one fracturing port. The valve sleeve is shiftable to allow fluid through the least one fracturing port. The production assembly comprises a production sleeve positioned within a production outer housing comprising at least one screen port and at least one production port. A sand screen assembly disposed around the production outer housing. The production sleeve shiftable by a ball to allow fluid through the at least one screen port and the at least one production port.

Abstract: A backup ring for a frac plug. The backup ring may include a plurality of segments defined by a plurality of slots, where each segment is defined by a sequential pair of the plurality of slots. The backup ring may also include a plurality of buttons, wherein at least one button is disposed on each segment. The backup ring creates a backup anchor for the sealing element and reduces or prevents extrusion of the sealing element.
