SYSTEM AND METHOD FOR ACQUIRING INFORMATION DURING UNDERGROUND DRILLING OPERATIONS

摘要

A preferred method for acquiring information during an underground drilling operation includes providing a sensing device (12) capable of acquiring information concerning the underground drilling operation from a down-hole location on a selective basis in response to an input from the surface, and drilling for a first period of time. The preferred method also includes sending the input to the sensing device after drilling for the first period of time, and drilling during a second period of time while acquiring the information using the sensing device.
