    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.

    摘要: A method includes obtaining a first set of survey data at a first point along a wellbore, estimating a present wellbore position based on at least the first set of survey data, determining a related ellipse of uncertainty at the present wellbore position, comparing the related ellipse of uncertainty of the present wellbore position to a threshold, and selecting a methodology for a subsequent survey based on a comparison of the related ellipse of uncertainty to the threshold.
