US Patent:

7757552, Jul 20, 2010

Filed:

Jan 8, 2008

Appl. No.:

11/970823

Inventors:

Christopher C. Bogath - Cheltenham, GB
Kimi M. Ceridon - Houston TX, US
Kate I. Gabler - Sugar Land TX, US
Minh Trang Chau - Sugar Land TX, US

Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 47/00

US Classification:

7315249

Abstract:

An apparatus and method for determining forces on a downhole drilling tool is provided. The downhole tool is provided with a drill collar operatively connectable to the drilling tool, and a sensor mounted about the drill collar. The sensor is adapted to measure deformation of the drill collar whereby forces on the drilling tool are determined. The sensor may be part of a force measurement system, a strain gauge system or a drilling jar system. The drill collar is adapted to magnify and/or isolate the deformation applied to the drill string.

10/710823

Inventors:

JONATHAN GUIDRY - PEARLAND TX, US
MINH CHAU - SUGAR LAND TX, US

Assignee:

SCHLUMBERGER TECHNOLOGY CORPORATION - SUGAR LAND TX

International Classification:

G01V001/00
G01V003/18

US Classification:

367035000, 367025000, 367053000, 367073000, 367069000, 324366000, 324351000

Abstract:

A method for displaying a bottom-hole assembly (BHA) using vector graphics includes parsing and interpreting BHA source data to produce data packets corresponding to BHA components; assembling the BHA using vector graphics components in a vector graphics library, wherein the vector graphics components represent the BHA components; and displaying the BHA at a selected scale.

Appl. No.:

09/579609

Inventors:

Minh T. Chau - Sugar Land TX
Dominic P. McCann - West Vancouver, CA

Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

G01V 318

US Classification:

702 9

Abstract:

The invention uses the continuous inclination, direction and tool-face information supplied from either an MWD tool and/or a rotary steerable drilling system, and/or other downhole equipment, e. g. , the at-bit inclination measurement (AIM), to give a prediction of the tendency of a rotary, steerable, or rotary steerable system. These measurements are used with a finite element mathematical model of the drilling process to continually calibrate in real-time the drilling parameters that are not obtainable from measurements, and to refine the subsequent tendency prediction in real-time. The continuous data will be used in conjunction with the accepted survey measurements (which occur less frequently than the continuous inclination and direction measurements) so that the optimum slide and rotation ratio between well sections can be selected, and drilling targets can be more accurately hit.

International Classification:

E21B 44/00
E21B 7/04
E21B 47/024

Abstract:

A method can include receiving sensor data during drilling of a portion of a borehole in a geologic environment; determining a drilling mode from a plurality of drilling modes using a trained neural network and at least a portion of the sensor data; and issuing a control instruction for drilling an additional portion of the borehole using the determined drilling mode.
