Filed:

Nov 30, 2004

Appl. No.:

10/998781

Inventors:

Robert Lyngle Waters - Austin TX, US

Assignee:

General Electric Company - Schenectady NY

International Classification:

E21B 7/04

US Classification:

175 45, 175 61

Abstract:

A method to guide a drilling path of a second well in proximity to a first well including: applying a time-varying electrical current to a conductive casing or liner of the first well. From the drilling path of the second well, an electromagnetic field generated by the current in the first well is sensed. The drilling path trajectory of the second well is guided using the sensed electromagnetic field.

International Classification:

G01B 7/30

US Classification:

32420725

Abstract:

A method of determining the amount of travel of a rotating component that includes a rotor shaft includes providing a self-contained magnetically-powered encoder. The encoder includes an encoder rotor that extends outward from a sealed housing such that a clearance gap is defined between the rotor and housing. The method also includes rotatably coupling the encoder to the rotor shaft. The method further includes measuring a first position of the encoder rotor and determining a first rotational position measurement of the rotor shaft based on the encoder rotor. The method also includes rotating the rotor shaft to a second rotational position and determining a direction of rotation and a second rotational position measurement of the rotor shaft using the encoder. The method further includes determining a total rotational distance traveled by the rotor shaft between the first rotational position and the second rotational position.

Assignee:

GENERAL ELECTRIC COMPANY - Schenectady NY

International Classification:

E21B 7/04

US Classification:

175 45, 175 62

Abstract:

System and methods for guiding the drilling of a horizontal well are disclosed. A current is provided in at least one conductor positioned in a target vertical well. A magnetic field generated by the current is measured at a drilling assembly that is drilling the horizontal well. A direction from the drilling assembly to the target vertical well is determined based at least in part on the measured magnetic field. A distance from the drilling assembly to the target vertical well is determined based at least in part on the measured magnetic field. The determination of the distance includes determining at least one gradient.

International Classification:

E21B 4702

US Classification:

175 45

Abstract:

A method and apparatus for performing a surveying operation to locate a target subterranean ferromagnetic body having remanent or impressed magnetization. The surveying operation is conducted from an off-vertical borehole adjacent the target magnetic body using magnetic field sensing apparatus, and involves determining the range and direction of the subterranean target with respect to the location of the magnetic field sensing apparatus. Target direction is determined by measuring three magnetic field components and resolving the measured components into a resultant vector. Target range is determined by measuring total magnetic field intensity and target body magnetic field intensity gradient in the direction of the off-vertical borehole. Both static and time-varying fields may be detected by the subsurface apparatus. The methods and apparatus disclosed may be used in such diverse areas as the location of ore deposits, guidance systems for drilling off-vertical wells to intersect a previously drilled well, and location metallic objects underwater.
