Abstract
An apparatus and method are provided for obtaining formation data while drilling. The apparatus may include a drill string and a plurality of sensors. At least two of the plurality of sensors are spaced apart along the drill string a approximately the same distance as a length of a segment of the drill string. The segment of the drill string is either added to or removed from the rest of the drill string as the drill string moves in the borehole during a drilling operation. The method may include providing numerous sensors along a drill string and repeating a cycle of various functions. The cycle may include performing an operation moving the drill string relative to the borehole and stopping movement of the drill string. Additional functions may include changing an overall length of the drill string and performing the formation property while the drill string is relatively stationary.
