Abstract
A method for surveying a wellbore may include deploying a deployable wellbore survey tool into the wellbore, collecting survey data as the deployable survey tool traverses the wellbore, and determining wellbore position information based on the survey data. In one example the method may include landing the deployable wellbore survey tool on a component of a bottom hole assembly.
