Claims20
A SAGD system comprising:
- at least one borehole having a tubular therein;
- and
- at least one baffle disposed on the tubular, the baffle extending radially outwardly of the tubular into proximity with a formation.
A downhole configuration for a SAGD system comprising:
- a tubular;
- and
- one or more baffles on the tubular, the one or more baffles configured to be extendible in a radial direction from the tubular to reduce annular flow along the tubular when installed in a borehole.
A borehole system comprising:
- a borehole;
- and
- one or more metal-to-formation baffles extending radially to proximity with a formation interface.
A borehole system comprising:
- a tubular configured to be disposed within an open hole borehole, the tubular being intended to be exposed to a heated fluid;
- and
- one or more tubular-to-formation baffles spaced along the tubular and extending into proximity with the formation.
