Abstract

The invention relates to a method and a system of determining the position of a downhole tool in a borehole, comprising introducing a downhole tool into the borehole, the downhole tool comprising an actuating tool and a downhole measurement device, receiving downhole data representing the borehole, where the downhole data include at least a first downhole landmark position representing a location of a landmark in the borehole, receiving a first signal from a downhole measurement device, the first signal representing a downhole landmark of a borehole and a measured position of the downhole landmark, comparing the first signal to the first landmark position of the downhole data and generating a first correction value, generating a first corrected depth value by correcting the first signal with the first correction value, and transmitting a first actuating signal to actuate the actuatable tool in a downhole position based on the first corrected depth value. The invention also relates to a system for performing the method.
