APPARATUS AND METHODS FOR ENHANCED WELL CONTROL IN SLIM COMPLETIONS

摘要

Embodiments of the present invention relate to an apparatus and methods for enhanced well control in slim completions. An embodiment can include an electrical submersible pump (“ESP”) positioned within a casing and having at least a portion thereof extending outwardly from a production tubing positioned within the casing. The production tubing terminates adjacent a distal end portion of a pump discharge to thereby provide greater interstitial space between outer surfaces of the portion of the pump disposed to extend outwardly from the production tubing and inner walls of the casing. This increased interstitial space, for example, can assist in cost savings by reducing the rate of erosion damage to the ESP. Embodiments of the present invention can further include a valve connected to inner walls of the casing and positioned distal from the ESP to control the flow of hydrocarbons.

主权项

1. A system to enhance well control in slim completions in an oil well, the system comprising:
production tubing extending at partially into the well; and an electric submersible pump (ESP) assembly disposed at an end of the production tubing, the ESP assembly comprising:
a pump body portion having pump intake apertures in side surfaces thereof at a lower end, and pump discharge apertures at an upper end, so that when the ESP assembly is in position in the well the pump intake apertures are positioned below and outside the production tubing, and the discharge apertures are positioned within the production tubing; anda pump motor attached to and positioned below the pump body portion.
