    Abstract: TELEMETRY OPERATED CEMENTING PLUG RELEASE SYSTEM A plug release system (60) for cementing a tubular string (15) into a wellbore (24) includes: a wiper plug (60b); a tubular housing (61); a latch (66) for releasably connecting the wiper plug (60b) to the housing (61). The latch (66) includes: a fastener (71) engageable with one of the wiper plug (60b) and the housing (61); a lock (70) movable between a locked position and an unlocked position, the lock (70) keeping the fastener (71) engaged in the locked position; and an actuator (69) connected to the lock (70) and operable to at least move the lock (70) from the locked position to the unlocked position. The plug release system (60) further includes an electronics package (62) disposed in the housing (61) and in communication with the actuator (69) for operating the actuator (69) in response to receiving a command signal. 60a 0 69g 69s 66+ -70 -- 61 a 60a 72h'~ 72g 60b ~ 72g 72s 61b 78u 73g 62e 62b P-62r 62t 62 73p 69hc 62m73 68 67 61 c 76+- 6 h - 078b r' it- OA69 1feIl

    Abstract: Methods and apparatus enable expanding tubing in a borehole of a hydrocarbon well. According to some embodiments, an expander device includes a collapsible swage formed of collets, at least one slip arrangement and a hydraulic jack to stroke the swage through tubing to be expanded. In operation, expanding tubing may include securing an expansion tool to the tubing, lowering the tool and tubing into a borehole, actuating a collapsible expander of the expansion tool to an extended configuration, and supplying fluid pressure to a jack coupled to the expander thereby moving the expander through the tubing which is held by at least one of first and second tubing holding devices disposed respectively ahead of the expander and behind the expander.
