Filed:

Jan 13, 2004

Appl. No.:

10/757111

Inventors:

Jared M. Potter - San Carlos CA, US

Assignee:

Coretest Systems, Inc. - San Jose CA

International Classification:

G01N015/08
E21B049/00

US Classification:

73 38, 7315205

Abstract:

A compression cell for rock or soil core samples applies and restores lithostatic or overburden pressure to core samples extracted from wells drilled deep into the earth. A method of applying lithostatic pressure to a core sample is disclosed along with the apparatus which effects the application. The cell construction that maintains the litho static pressure and the process of utilizing the cell and sample under essentially deep earth ambient conditions are set forth.

International Classification:

E21B 7/18

US Classification:

175067000, 175091000

Abstract:

System and methods for creating shaped, non-circular boreholes in rocks especially for use with geothermal heat pump applications and for increasing wellbore support in applications such as horizontal oil and gas drilling are described. The systems and methods when applied to geothermal heat pumps create an elliptical shaped hole that is optimized for placing heat transfer tubes with a minimum of grout used. The significantly reduced cross-sectional area of the elliptical borehole also increases the overall drilling rate in rock and especially in hard rocks. In horizontal hard-rock drilling, creation of a horizontal non-circular borehole or modification of a circular borehole to a non-circular geometry is used to stabilize the borehole prior to casing insertion, and may also allow the use of lower mud pressures improving drilling rates. The system uses a non-contacting drilling system which in one embodiment uses a supersonic flame jet drilling system with a movable nozzle that swings between pivot points. In a second embodiment the elliptical shaped hole is created by an abrasive fluid or particle bearing-fluid or air jet drill that moves between pivot points. In another embodiment a non-contacting drill can use dual parallel nutating nozzles that create a pair of overlapping circular holes. The non-circular shaped hole is created by either the high temperature flame or water-particle jet or chemically active fluid jet as it removes rock material by erosion, dissolution and or thermal spalling. Modifications of circular boreholes to a generally elliptical shape can also be done using milling or jetting techniques.

International Classification:

E21B 10/60

US Classification:

175 17

Abstract:

Methods and apparatus for excavation of a borehole in a geological formation are provided. Such methods may include providing a thermal system capable of providing substantially hot fluid, and comprising at least one jet nozzle, providing a mechanical drilling system comprising a drill bit, directing the substantially hot fluid through the jet nozzle towards the geological formation causing an altered portion of geological formation to form, and removing the altered portion using the drill bit, thereby creating cuttings and producing a borehole in the geological formation.

International Classification:

G05D 1620

US Classification:

1374875

Abstract:

A pressure control assembly is disclosed. The assembly includes a pressure transducer for detecting upstream pressure. A diaphragm is used to regulate flow through the assembly, and is forced into a closed position by pressure from a fluid column. The pressure on the fluid column is controlled by a piston driven by a step motor. The step motor is activated in response to signals from the pressure transducer.
