Abstract
A method for estimating depth of a survey tool during a wellbore survey, the method comprising dropping the survey tool inside a drill pipe placed in a wellbore, generating, by an accelerometer included in the survey tool, a measurement signal as the survey tool moves through the drill pipe, identifying a first group of spikes appearing in the measurement signal, identifying a second group of spikes appearing in the measurement signal, and determining a depth of the survey tool at a first time during movement of the survey tool through the drill pipe based in part on the first group of spikes, the second group of spikes, and a dimension of the drill pipe.
