1. A wellbore production system for use with a wellbore having a casing containing hydrocarbon fluids, the system comprising:
a bailer vessel arranged to be received in the casing of the wellbore so as to be movable longitudinally along the casing between an upper position in proximity to a top end of the casing and a lower position arranged to be submerged in the hydrocarbon fluids at a predetermined depth within the casing;
the bailer vessel comprising (i) a production chamber, (ii) at least one bottom opening in communication with a bottom of the production chamber and arranged to receive the hydrocarbon fluids into the production chamber therethrough in the lower position of the bailer vessel, (iii) a bailer valve associated with said at least one bottom opening so as to be arranged to restrict removal of fluids from the production chamber through the at least one bottom opening when the bailer vessel is not in the lower position, and (iv) a top opening in communication with a top of the production chamber;
a lift assembly operatively connected to the bailer vessel through the top end of the casing and arranged to displace the bailer vessel between the upper position and the lower position thereof;
a wand member arranged to be supported within the casing in proximity to the top end of the casing such that a bottom end of the wand member is arranged to be received into the production chamber through the top opening of the bailer vessel in the upper position of the bailer vessel;
the wand member including (i) a receiving chamber, (ii) at least one bottom opening in communication with a bottom of the receiving chamber and arranged to receive the hydrocarbon fluids into the receiving chamber therethrough as the bailer vessel approaches the upper position and receives the bottom end of the wand member therein, (iii) a wand valve associated with said at least one bottom opening so as to be arranged to restrict removal of fluids from the receiving chamber through the at least one bottom opening when the bailer vessel is not in the upper position, and (iv) an outlet opening in communication with the receiving chamber;
an outlet passage arranged to communicate from the outlet opening of the wand member to a discharge location externally of the casing; and
a sealing interface between the wand member and the bailer vessel which seals the top of the production chamber in the bailer vessel closed when the wand member is received within the bailer vessel, the sealing interface being arranged to maintain a seal between the wand member and the bailer vessel throughout relative sliding movement between the wand member and the bailer vessel when the bailer vessel is in proximity to the upper position.
