Systems and Methods for Core Recovery |
| 摘要 |
The present disclosure relates to systems and methods for determining the retraction rate of a coring bit based on sensed environmental factors associated with coring operations. In certain embodiments, a downhole tool is positioned in a wellbore extending into a subterranean formation, coring operations are commenced by rotating a coring bit of the downhole tool and extending the rotating coring bit into a first location along a sidewall of the wellbore, a first environmental factor associated with the coring operations at the first location is sensed, and a rate of retraction of the coring bit at the first location is determined based on the first sensed environmental factor. |

1. A method, comprising:
positioning a downhole tool in a wellbore extending into a subterranean formation; commencing coring operations by rotating a coring bit of the downhole tool and extending the rotating coring bit into a first location along a sidewall of the wellbore; sensing a first environmental factor associated with the coring operations at the first location; and determining a rate of retraction of the coring bit at the first location based on the first sensed environmental factor. |
