Optimized Liquid or Condensate Well Production

摘要

A dedicated borehole for an ESP or artificial lift mechanism communicates with a sump or wellbore to collect liquids and/or condensate from one or more other bores where there can be laterals into a producing formation. If the ESP or artificial lift mechanism needs to be replaced the dedicated bore with the ESP or artificial lift mechanism can be closed off and the ESP or artificial lift mechanism removed without taking out the main bore or bores connected to the sump or wellbore. Those bores can continue to produce gas as liquids and/or condensate accumulate in the sump, sumps or wellbore. When the ESP or artificial lift mechanism is replaced the liquid can be pumped to surface without interruption of the gas production.

主权项

1. A well configuration, comprising:
at least one main borehole connected to a collection sump for produced liquid accumulation, said main borehole conducting produced gas to a remote location; an auxiliary borehole further comprising an artificial lift device connected to said sump for removal of said produced liquid to the remote location; a barrier in said auxiliary bore selectively closed to allow removal of said artificial lift device while continuing to produce gas to the remote location through said main borehole.
