US Patent:

6357523, Mar 19, 2002

Filed:

Nov 19, 1999

Appl. No.:

09/444029

Inventors:

Joseph A. Zupanick - Pineville WV

Assignee:

CDX Gas, LLC - Dallas TX

International Classification:

E21B 4300

US Classification:

166 52, 166 50, 166245, 299 12

Abstract:

Improved method and system for accessing subterranean deposits from the surface that substantially eliminates or reduces the disadvantages and problems associated with previous systems and methods. In particular, the present invention provides an articulated well with a drainage pattern that intersects a horizontal cavity well. The drainage patterns provide access to a large subterranean area from the surface while the vertical cavity well allows entrained water, hydrocarbons, and other deposits to be efficiently removed and/or produced.

International Classification:

E21B 4700

US Classification:

1662552, 1662413, 166104, 405 55

Abstract:

A cavity positioning tool is provided that includes a head piece adapted to receive a downhole string having a longitudinal axis. A plurality of blunt arms are coupled to the head piece. The blunt arms are operable to be radially extended outward from a first position of substantial alignment with the longitudinal axis to a second extended position.

International Classification:

E21B 704

US Classification:

175 61, 175 62, 166 50, 166 52, 166245

Abstract:

A method and system for accessing subterranean zones from the surface includes a substantially vertical well bore extending from the surface to a target zone, and an articulated well bore extending from the substantially vertical well bore to the target zone. The articulated well bore diverges from the substantially vertical well bore between the surface and the target zone. The system also includes a well bore pattern extending from the articulated well bore in the target zone operable to collect resources from the target zone. The system also includes a subsurface channel operable to communicate resources from the well bore pattern to the substantially vertical well bore. The system further includes a vertical pump disposed in the substantially vertical well bore and operable to lift resources collected in the substantially vertical well bore to the surface.

Joseph A. Zupanick - Pineville WV

Assignee:

CDX Gas, LLC - Dallas TX

International Classification:

E21B 2300

US Classification:

166243, 166105, 1662411

Abstract:

A subterranean cavity positioning system includes a down-hole device and a cavity positioning device rotatably coupled to a well portion of the down-hole device. The cavity positioning device includes a counterbalance portion operable to automatically rotate the cavity positioning device from a retracted position to an extended position as the cavity positioning device transitions from a well bore into the subterranean cavity. The counterbalance portion is also operable to align the cavity positioning device with the well bore as the down-hole device is withdrawn from the subterranean cavity.

International Classification:

F04B 2314

US Classification:

417 85, 417278, 417284, 13756535

Abstract:

A fluid level controlled pumping system includes a pumping unit disposed within a fluid cavity. The pumping unit includes an inlet operable to receive a fluid to be pumped from the fluid cavity. The system also includes a valve slidably coupled to the pumping unit. The valve includes a passage for receiving pumped fluid from an outlet of the pumping unit. In response to a decreasing fluid level within the fluid cavity, movement of the valve relative to the pumping unit aligns the passage with a port of the pumping unit to recirculate the pumped fluid from the outlet to the inlet.
