Reinforced Legs For Ice Worthy Jack-Up Drilling Unit
US Patent:
2012012, May 24, 2012
Filed:
Oct 21, 2011
Appl. No.:
13/278795
Inventors:
Peter G. Noble - Spring TX, US
Randall S. Shafer - Houston TX, US
Dominique P. Berta - Katy TX, US
Michael B. Winfree - Anchorage AK, US

Assignee:
ConocoPhillips Company - Houston TX
International Classification:
E02B 17/08, E21B 7/00
US Classification:
405196, 175 57
Abstract:
The invention relates to an ice worthy jack-up rig that may extend the drilling season in shallow water off shore Arctic or ice prone locations. The inventive rig would work like a conventional jack-up rig while in open water with the hull jacked up out of the water. However, in the event of ice conditions, the legs are held in place by cans embedded in the sea floor to resist lateral movement of the rig and the hull is lowered into the water into an ice defensive configuration. The hull is specifically shaped with an ice-bending surface to bend and break up ice that comes in contact with the hull while in the ice defensive configuration.

Drilling With Casing And Retrievable Bit-Motor Assembly
US Patent:
5472057, Dec 5, 1995
Filed:
Feb 9, 1995
Appl. No.:
8/387959
Inventors:
Michael B. Winfree - Anchorage AK
Assignee:
Atlantic Richfield Company - Los Angeles CA
International Classification:
E21B 700
US Classification:
175 57
Abstract:
A wellbore is formed in the earth with an elongated, non-rotating tubular drillstem which may consist of a well casing or liner and including an expendable sub and reamer bit part connected to the lower distal end of the drillstem. A retrievable drilling fluid operated motor and drive member assembly are disposed in the drillstem. The motor and drive member include pressure fluid responsive mechanism for engagement with and disengagement from the reamer bit part to rotatably drive the reamer bit part and a central bit part connected to the drive member without rotating the casing type drillstem. The motor, drive member and central bit part may be retracted from the drillstem upon completion of drilling operations without retrieving the expendable reamer bit part.
