Patent number: 11634958Abstract: A downhole tool having a mandrel, and a bottom slip disposed around the mandrel. The bottom slip includes a circular body having a one-piece configuration characterized by a plurality of slip segments by at least partial material connectivity therearound. The bottom slip is made of a filament wound composite material, which means the bottom slip has a plurality of layers joined by respective interface layers. An outer slip surface of at least one of the plurality of slip segments is defined in cross-section by a plane P that intersects a longitudinal axis of the downhole tool at an angle a1 when the bottom slip is in an unset position.Type: GrantFiled: June 24, 2021Date of Patent: April 25, 2023Assignee: The WellBoss Company, LLCInventors: Evan Lloyd Davies, Yi Xia, Luis Miguel Avila, David Hughes, Gabriel Slup, Ashton E.
