Abstract

Systems and methods for a guided extend reach tractor are disclosed. The method includes installing a packer and a tractor string operatively connected to the packer in a borehole; lowering the guided extend reach tractor into the borehole; supplying power, via a power source, to the guided extend reach tractor; attaching the guided extend reach tractor to the tractor string using an electromagnet; and clamping the guided extend reach tractor onto the tractor string. The method further includes activating helical bars to propel the guided extend reach tractor forward or backward in the borehole; performing well intervention operations in the borehole; and extracting the guided extend reach tractor from the borehole.
