Abstract
A drilling system for drilling and completing a lateral borehole from a main borehole comprises a liner unit for storing one or more prefabricated liners for installation into the lateral borehole; and a drilling unit operable to drill the lateral borehole into the formation surrounding the main borehole and to install the prefabricated liner in the lateral borehole after drilling. A method of drilling a lateral borehole from a main borehole using such a drilling system comprises positioning the system in the main borehole at a location of interest; operating the drilling unit to drill a lateral borehole from the main borehole; completing the lateral borehole by deploying the liner from the liner unit into the lateral borehole.
Claims22
A drilling system for drilling and completing a lateral borehole from a main borehole, comprising:
- a liner unit for storing at least one liner segments for installation into the lateral borehole;
- and
- a drilling unit operable to drill the lateral borehole into the formation surrounding the main borehole and to install the at least one liner segments to form a liner in the lateral borehole after drilling.
A drilling system for drilling and completing a lateral borehole from a main borehole, comprising:
- a liner unit for storing at least one liner segments for installation into the lateral borehole;
- and
- a drilling unit operable to drill the lateral borehole into the formation surrounding the main borehole and to install the at least one liner segment to form a liner in the lateral borehole as drilling of the lateral borehole progresses.
