Abstract:
1. A method for developing a wellbore deviation survey, comprising: collecting wellbore deformation data using a caliper at each of a plurality of depths within a wellbore; collecting wellbore deviation data at one or more of the plurality of depths; collecting tool orientation data using an orientation tool at one or more of the plurality of depths; orienting the wellbore deformation data and the wellbore deviation data with the tool orientation data; determining simulated wellbore deformation data at each of a plurality of simulation depths using the oriented wellbore deformation data, including simulating a position of a model tool at the plurality of simulation depths along the length of a model wellbore, wherein each of the plurality of simulation depths corresponds to one of the plurality of depths within the wellbore; determining simulated wellbore deviation data at one or more of the plurality of simulation depths using the simulated wellbore deformation data; and developing the wellbore deviation survey by calibrating the simulated wellbore deviation data, including adjusting the simulated wellbore deviation data at one or more of the plurality of simulation depths where the simulated wellbore deformation or deviation data does not agree with the oriented wellbore deformation or deviation data.
