Abstract
Methods and apparatus for producing hydrocarbons from a well, and especially for producing gas from low pressure gas wells containing water, are disclosed. An electrical submersible pump is attached to and in fluid communication with the bottom end of a string of pipe joints or tubing extending in the well bore from the surface to below the water-containing gas interval, a further string of pipe joints or tubing having one or more openings therein at the bottom end thereof extends from the surface to below the water-containing gas interval, and water supplied from the surface via the further string of pipe joints or tubing along with water from the water-containing gas interval is constantly pumped by the electrical submersible pump at a rate sufficient to prevent the pump from overheating and failing and to prevent production-limiting water build-up in the well bore.
