Horizontal Bore Cryogenic Drilling Method
US Patent:
7000711, Feb 21, 2006
Filed:
Feb 9, 2004
Appl. No.:
10/774678
Inventors:
Thomas J. Miller - Shrewsbury MO, US
John R. Jansen - West Bend WI, US
John R. Jansen - West Bend WI, US
Assignee:
CH2M Hill, Inc. - Englewood CO

Ruekert & Meilke, Inc. - Waukesha WI
International Classification:
E21B 7/00, E21B 7/08
US Classification:
175 65, 175 18, 166 50
Abstract:
A horizontal bore cryogenic drilling method includes in a first embodiment forming a pilot hole of a first select diameter along a desired path of the horizontal bore. A grindable casing is inserted into the guide bore. A cryogenic fluid is flowed through the grindable casing to form a freeze zone of frozen moisture adjacent the grindable casing having a second select diameter. A primary bore is formed having a third select diameter greater than the first diameter and less than the second select diameter within the freeze zone along the desired path of the horizontal bore with the grindable casing in place. The second diameter is selected to be sufficiently greater than the third select diameter to prevent collapse of the freeze zone. Another embodiment of the invention is a method of forming a horizontal bore in an earth formation including providing a drill string having a conduit communicating with a cutting tool for engaging the earth formation. A cryogenic fluid is flowed through the conduit and the cutting tool to drive the cutting tool and remove cuttings from a bore formed by the cutting tool.
Method For Removing Radioactive Substances From Affecting Water Wells
US Patent:
6881347, Apr 19, 2005
Filed:
Jan 14, 2003
Appl. No.:
10/341790

Assignee:
Ruekert & Mielke, Inc. - Waukesha WI
International Classification:
C02F001/28
US Classification:
210670, 210682, 210747
Abstract:
The natural ability of an aquifer formation to remove radionuclides from ground water is recharged by injecting a leaching solution a well. The leaching solution replaces the radionuclides at natural sorption sites in the aquifer formation with ions that can be displaced subsequently by other radionuclides in the ground water. The leaching solution remains in the aquifer formation for a given period of time after which it is pumped out through the well. Thereafter, as water is pumped from the well, other radionuclides become lodged at the sorption sites in the aquifer formation thus being removed from the water.
Method For Improved Water Well Production
US Patent:
5579845, Dec 3, 1996
Filed:
Feb 7, 1995
Appl. No.:
8/385184

International Classification:
E21B 4300
US Classification:
166299
Abstract:
A non-destructive method for stimulating, refurbishing, or otherwise increasing production from water wells, using pressure waveforms and mass displacement within the well bore volume. The non-destructive methods are useful in a variety of water production contexts and can be modified downhole to meet specific performance requirements.
