Apparatus and method for placement of downhole tools using a visual imaging device

摘要

A method of orienting depth and direction (azimuth) of a guide device used to direct tools for the creation of a lateral borehole extending from a wellbore in an earthen formation, utilizing a visual imaging tool. The method including running a tool string into a wellbore, the tool string comprising a guide device and a visual imaging device, visually imaging the wellbore at a range of depths and orientations in the wellbore, and aligning the guide device within the wellbore in preparation of drilling tools to be used for the creation of a lateral borehole in an earthen formation.

1. A method of orienting depth and direction (azimuth) of a guide device used to direct tools for the creation of a lateral borehole extending from a wellbore in an earthen formation, comprising:
running a tool string into a wellbore, the tool string comprising a guide device and a visual imaging device; visually imaging the wellbore at a range of depths, while rotating the visual imaging device to observe a view of at least 90 degrees at a range of depths in the wellbore; aligning the guide device within the wellbore in preparation of drilling tools to be used for the creation of a lateral borehole in an earthen formation wherein the lateral borehole is generally perpendicular to the wellbore.
