This Oilfield Multishot Survey Tool represents a new survey tool development utilizing a three axis Silicon accelerometer / magnetometer set to measure downhole surveying parameters and borehole temperature on a timed basis. The multishot tool provides definitive survey information, corrected for magnetic interference from the drilling assembly, before the well is cased. The tool is available in a number of configurations – of which the 1 3/8" diameter version will fit within a thermal heat shield in a 1 ¾" outer pressure housing
