Filed:

Jun 29, 2001

Appl. No.:

09/896025

Inventors:

Jeff Merecka - Cypress TX
David Camp - Cypress TX

Assignee:

S S Trust - Commerce City CO

International Classification:

E21B 704

US Classification:

175 62, 175 73, 175203, 4051541

Abstract:

The invention relates to a system for coiled tubing drilling of substantially horizontal shallow depth boreholes for installation of transmission or conveyance lines. A mobile platform mounts a coiled tubing reel and an adjustably mounted injector head. On the leading end of the coiled tubing is a drilling assembly, including a drill, a drill motor, and an orienter. Once the borehole has been drilled by pushing the drilling assembly through the borehole and exiting the earths surface, a back reamer may be attached for enlarging the borehole as the coiled tubing is pulled back through the borehole. Once the borehole has been properly sized, the transmission or conveyance line may be attached to the leading end of the coiled tubing and the transmission or conveyance pipe pulled back through the borehole.

International Classification:

G01T 100

US Classification:

250393, 25036301

Abstract:

A method and apparatus are provided for assaying a waste container. The method includes the steps of forming a plurality of slices through a volume of the waste container, performing a relatively fast passive prescan to measure a level of radioactivity of each of the plurality of slices and identifying at least some slices of the plurality of slices having a relatively high level of radioactivity. In addition, the method includes the steps for performing a relatively fast active prescan of the drum to determine the average attenuation of the plurality of slices. The method further includes the steps of determining an passive assay time for the identified slices based upon the measured radioactivity and average attenuation and performing relatively slow passive and active CT scans of the identified slices based upon the determined passive and active CT assay time to quantify a source of the measured radioactivity by weight.

International Classification:

E21B 1026

US Classification:

175 53, 175 62, 405184

Abstract:

The backreamer assembly for enlarging shallow depth boreholes in an earthen environment includes a substantially conical cutting surface. Contained within the substantially conical cutting surface is a speed reduction, torque increasing gearbox which transmits rotational power from a drive motor to the substantially conical cutting surface.

Inventors:

David Camp - Cypress TX, US

International Classification:

E21B 7/08

US Classification:

175 61, 175 73, 175 26, 175 45, 175 75

Abstract:

The disclosed orienter for use in drilling a subterranean borehole enables use of the torque provided by the drilling motor to both orient the rotating drill bit for drilling an arcuate section of the borehole and rotating the orienter housing, including a fixed bend for drilling a straight section of the borehole.

David M Camp - Houston TX, US

Assignee:

Amkin Technologies, LLC - Houston TX

International Classification:

E21B 25/16

US Classification:

175 45, 175 61, 702151

Abstract:

A position indicator for use in a dowhole tool and method for use is provided. The position indicator has a sensor that detects the position of a portion of the tool as the tool rotates. The sensor sends a signal to a controller to relay the position of the tool to a controller and/or operator. The rotational position of the tool may be controlled in order to perform downhole operations.

Abstract:

The invention relates to a system for coiled tubing drilling of substantially horizontal shallow depth boreholes for installation of transmission or conveyance lines. A mobile platform mounts a coiled tubing reel and an adjustably mounted injector head. On the leading end of the coiled tubing is a drilling assembly, including a drill, a drill motor, a tracking device, and an orienter. Once the borehole has been drilled by pushing the drilling assembly through the borehole and exiting the earth's surface, a back reamer may be attached for enlarging the borehole as the coiled tubing is pulled back through the borehole. Once the borehole has been properly sized, the transmission or conveyance line may be attached to the leading end of the coiled tubing and the transmission or conveyance pipe pulled back through the borehole.

Appl. No.:

12/985545

Inventors:

David M. Camp - Houston TX, US

International Classification:

E21B 7/04

US Classification:

175 61, 175 73

Abstract:

Embodiments described herein comprise a system and method for controlling directional drilling. The system includes a conveyance for conveying a bottom hole assembly BHA into a wellbore. The BHA may include a bent housing, a drilling tool and a motor for rotating the bent housing in the wellbore. The system further includes a conveyance rotation device for rotating the conveyance in the opposite direction of the bent housing. The direction of the bent housing may be controlled by controlling the rotational speed of the bent housing and the conveyance while drilling.
