摘要： A non-damaging slip assembly includes slips having grit on a smooth surface, the slips preferably made from a ductile material, such that the slips do not cause damage to the wall of a tubular when the slips are set. The slips fail under tensile force during setting. The cone used to expand the slips may have slits that narrow during setting of the slips. The slip assembly may be used to anchor a variety or devices inside a tubular. A drillable, non-damaging bridge plug using the non-damaging slip assembly has a threaded mandrel holding the cone by threads inside the cone. When the slips are set, the slits in the cone narrow such that threads in the cone do not allow rotation of the slips as they are drilled. The bridge plug can be drilled by a PDC bit without damaging the tubular.

摘要： Multiple ball launch assemblies comprise a plurality of ball launch pods disposed around an outer wall surface of a housing. The ball launch pods are operatively associated with a flow tube disposed within the housing. An actuator assembly rotates the flow tube to align a first opening in the flow tube with a first ball launch pod so that a first ball is launched into the wellbore. Further rotation of the flow tube aligns subsequent openings in the flow tube with subsequent corresponding ball launch pods so that subsequent balls are launched into the wellbore.

摘要： Bypass assembly 100 includes stinger 150 received by receptacle bore 172 of tubular receiver 120 attached to tube 106. Bypass pathway 140 connects stinger port(s) (158, 158′) to slip hanger 122 supported hydraulic conduit 108 to bypass the tube 106. Tube 106 can be a subsurface safety valve or hydraulic nipple anchored within production tubing. Bypass assembly 200 includes upper 202 and lower 203 hydraulic nipples in production tubing 210, with respective tubular anchor seal assemblies (220, 230) engaged therein. Bypass pathway 214 connects hydraulic conduit 208 to slip hanger 242 supported hydraulic conduit 216 to bypass tubular anchor seal assemblies (220, 230). Bypass assembly 300 includes upper 302 and lower 303 hydraulic nipples in production tubing 310, with respective tubular anchor seal assemblies (320, 330) engaged therein. Bypass passage 318 connects stinger 350 to slip hanger 342 supported hydraulic conduit 316 to bypass tubular anchor seal assemblies (320, 330).
