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.
