Abstract:
A method may include providing a drill string positioned in a wellbore including a measurement tool. The method may include taking a measurement with the measurement tool at a first location; coupling a pipe stand including a first selected number of tubular segments to the drill string, the first selected number being two or more; lowering or advancing the drill string into the wellbore the length of the pipe stand; taking a measurement with the measurement tool at a second location; raising the drill string the length of a tubular segment; removing a second selected number of tubular segments from the drill string; taking a measurement with the measurement tool at a third location; raising the drill string the length of the first selected number of tubular segments; removing the first selected number of tubular segments; and taking a measurement with the measurement tool at a fourth location.
