Appl. No.:

13/010502

Inventors:

Bronwyn Michelle Calleja - Balikpapan, ID
Barry McKay - Houston TX, US

Assignee:

Hilliburton Energy Services, Inc. - Houston TX

International Classification:

G01V 3/00

US Classification:

3408541

Abstract:

A method and system to render a graphic display that includes a color-coded risk indicator to facilitate the steering of a drill string during subterranean drilling. The system comprises a receiver to receive measurement data from downhole instrumentation forming part of the drill string during the drilling of a well bore in a geological formation, and an exit risk determining module to determine an exit risk value based at least in part on the measurement data. The exit risk value is indicative of a risk of exiting of the formation by the drill string. A display module is provided to render the graphic display of decision information, to assist steering of the drill string. The color-coded exit risk indicator comprises a colored area having a color indicative of the exit risk value, the color of the colored area being changeable in response to changes in the exit risk value. The graphic display may show a wellbore trajectory in relation to a formation boundary, with the color-coded risk indicator comprising an area extending between the wellbore trajectory and the formation boundary.

Abstract:

For some embodiments, a software application for correcting sensor data in a remote database () according to magnetic correction parameters obtained from a geophysical survey service, the sensor data obtained from directional instruments on a well tool (). The remote database resides in a field computer () at a well site, and a copy of the remote database may also reside in a real time operations computer system. For some embodiments, the sensor data for particular depths and measurement times are stored as rows in a table (FIG. ). The correction software may write new rows in the remote database with the corrected sensor data, or may write new rows in a second database for storing corrected sensor data (FIG. ).
