摘要

A system (30) for drilling to a position relative to a geological boundary in a geological formation includes a sensor pack (26) for sensing parameters associated with a drilling operation carried out in the geological formation by a drill (10). A data storage module (34) stores a geological model of the geological formation and data relating to the sensed parameters, the geological model including data relating to the geological boundary. A processor module (32) is configured to monitor the drilling operation using the data related to the sensed parameters and to locate the position of a drill bit of the drill (10) in the geological formation and its corresponding position within the geological model. The processor module (32) is further configured to generate an end point at a defined position relative to the geological boundary. A drill controller (24) communicates with the processor module (32), the drill controller (24) being configured to control operation of the drill 10 and to cause the drill (10) to cease drilling when the end point has been reached.
