    摘要: A method is disclosed which utilizes multiple overlapping surveys to estimate a position in a wellbore and related position uncertainty. Multiple surveys are often taken over the same portion of a wellbore either concurrently or sequentially and/or using various instruments. Each survey generates an estimated survey position and related uncertainty for a given location in the wellbore. By combining the estimated survey positions and uncertainties for these overlapping surveys, a resultant position and related ellipsoid of uncertainty is estimated. This resultant position estimates a position in the wellbore by incorporating the estimated survey positions and uncertainties of multiple overlapping surveys.

    摘要: 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.
