US 2025/0154830 A1 · SYSTEMS AND METHODS FOR CONTROLLING DRILLING BASED ON ESTIMATED POSITION OF BOTTOM HOLE ASSEMBLY

Abstract

A method and a system for estimating a position of a bottom hole assembly (BHA) during drilling of a wellbore is described. The method includes receiving, by a control system, toolface information and non-survey sensor information from downhole sensors during drilling of the wellbore. Based on the non-survey sensor information, an estimated amount of progress made by the drill bit since a prior estimate of the location of the BHA located in the wellbore is calculated. An estimated location of the BHA is calculated using the toolface information and the estimated amount of progress of the drill bit. The method further includes determining whether survey data has been received. In response to receiving the survey data, the estimated location of the BHA can be updated. Responsive to the estimated location of the BHA, one or more drilling parameters can be adjusted.
