Drill String Tubular with a Detection System Mounted Therein

A drill string comprising:

• a drill collar comprising an outer surface and a flowbore extending therethrough, the flowbore conveying a drilling fluid;
• a first tube bank formed in the outer surface of the drill collar;
• a first detection system mounted in the first tube bank and comprising an outer surface substantially flush with the outer surface of the drill collar, the first detection system operable to measure a portion of the data;
• a second tube bank formed in the outer surface of the drill collar, the second tube bank offset relative to the first tube bank by at least one of an axial distance and a circumferential distance and comprising an outer surface substantially flush with the outer surface of the drill collar;
• and
• a second detection system mounted in the second tube bank and comprising an outer surface substantially flush with the outer surface of the drill collar, the second detection system operable to measure another portion of the data;
• and
• wherein the first and the second detection systems receive power from and transmit the data to components positioned uphole and electrically coupled thereto.

A measurement system comprising:

• a tubular suspended downhole and comprising an outer surface;
• a first tube bank formed in the outer surface of the tubular;
• and
• a first detection system disposed within the first tube bank, the first detection system comprising:
• a plurality of detectors, each detector comprising:
• a Geiger Muller tube operable to measure radiation;
• and
• a pressure housing disposed thereabout;
• and
• a cover plate coupled to the tubular, the cover plate moveable between a closed position, wherein the cover plate extends over the first tube bank forming a barrier between the detectors and an annulus formed by the tubular and a formation surrounding the tubular, and an open position, wherein the detectors are accessible.
