Abstract
A well completion system for reducing the pressure drop in fluids produced from a downhole formation (14) traversed by a wellbore (32) comprises a production tubing (30) used to bring the formation fluids to the surface that is positioned within a well casing (34) that lines the wellbore (32). An expander member (56) is positioned within the production tubing (30) and travels longitudinally within the production tubing (30) to expand the flow area within the production tubing (30) once the production tubing (30) has been installed downhole, thereby reducing the pressure drop in fluids produced through the production tubing (30).
Claims56
A method for reducing the pressure drop in fluids produced through a production tubing from a downhole formation traversed by a wellbore, the method comprising the steps of:
- lining the wellbore with a well casing;
- disposing the production tubing within the well casing;
- and
- expanding the production tubing downhole, thereby reducing the pressure drop in fluids produced through the production tubing and increasing production.
A method for reducing the pressure drop in fluids produced through a production tubing from a downhole formation traversed by a wellbore, the method comprising the steps of:
- lining a first section of the wellbore with a first well casing having an inner diameter;
- lining a second section of the wellbore with a second well casing having an inner diameter that is smaller than the inner diameter of the first well casing;
- disposing the production tubing within the first and the second well casings;
- and
- expanding the production tubing downhole that is disposed within the first well casing.
A method for reducing the pressure drop in fluids produced through a main section of production tubing disposed in a multilateral well, the method comprising the steps of:
- lining at least a main wellbore portion of the multilateral well with a well casing;
- extending first and second branch wellbores from the main wellbore, the second branch wellbore being farther downhole than the first branch wellbore;
- disposing the main section of production tubing within the well casing in the main wellbore, a first branch section of production tubing within the first branch wellbore and a second branch section of production tubing within the second branch wellbore;
- and
- expanding the production tubing downhole that is uphole of the first branch wellbore.
A method for optimizing production from a downhole formation traversed by a wellbore, the method comprising the steps of:
- lining the wellbore with a well casing;
- disposing a production tubing within the well casing;
- testing the productive capability of the formation to determine whether production from the formation is constrained by the production tubing;
- and
- expanding the production tubing downhole if the production from the formation is constrained by the production tubing to increase production.
A well completion system for reducing the pressure drop in fluids produced therethrough from a downhole formation traversed by a wellbore, the system comprising:
- a production tubing that is positioned within a well casing lining the wellbore;
- and
- an expander member positioned within the production tubing that travels longitudinally within the production tubing to expand the production tubing downhole, thereby reducing the pressure drop in fluids produced through the production tubing and increasing production.
