COLD HEAVY OIL PRODUCTION SYSTEM AND METHODS

摘要

A system for producing hydrocarbons and sand from a formation includes a wellbore having a substantially horizontal portion. In addition, the system includes a liner (16) disposed in the substantially horizontal portion. The liner has a longitudinal axis and includes a plurality of slots. Each slot is configured to pass sand from the formation into the wellbore. Further, the system includes a production string extending through the wellbore. Still further, the system includes a pump (18) disposed at a downhole end of the production string in the liner. The pump has a central axis, an outlet coupled to the downhole end of the production tubing, and an inlet distal the production string. The pump is configured to pump hydrocarbons and sand from the formation to the surface. The central axis of the pump is oriented at an angle a measured downward from vertical. The angle a is between 60° and 90°.
