Abstract: Hydrocarbons are produced from a wellbore using a wand member supported within the top end of the casing and a bailer vessel supported within the casing of the wellbore to reciprocate between (i) a lower position submerged in the hydrocarbon fluids at a predetermined depth within the casing such that fluids enter a production chamber of the bailer vessel and (ii) an upper position receiving the wand member therein through an open top of the bailer vessel so as to force the hydrocarbon fluids in the production chamber under pressure through a bottom opening in the wand member and into a receiving chamber of the wand member. The hydrocarbons in the wand member are then discharged to a location externally of the casing for storage.

Abstract: In a coiled tubing assembly for use in a wellbore, the tubing assembly uses longitudinally spaced apart clamping members to clamp two or more coiled tubing members alongside one another. Each clamping member includes a clamping portion extending circumferentially about each coiled tubing member so as to be rotatable in relation thereto, and a connecting portion joined between the clamping portions. A longitudinal positioning element is fixed relative to one of the tubing members in association with each clamping member such that the clamping member remains pivotal relative to the positioning element and the tubing members upon which it is fixed. The longitudinal positioning element thus only restricts the respective clamping assembly in the longitudinal direction along the tubing members without restricting relative twisting between the tubing members.

Abstract: A motor and pump assembly for use in a wellbore includes a downhole motor producing a rotary output, a reciprocating plunger for pumping fluid up a tubing string, and a drive linkage supported within the hollow tubular housing having a rotary input in connection with the rotary output of the motor and a reciprocating output which is arranged for longitudinal sliding movement with the reciprocating plunger and which is driven responsive to rotation of the rotary input to drive the plunger. The drive linkage includes a lead screw, a sleeve member having a closed end coupled to the plunger, and a follower supported on an inner side of the sleeve member in operative connection to the lead screw to drive longitudinal sliding movement of the sleeve member responsive to rotation of the lead screw.
