Enhance drilling operations safety by improving Collision Avoidance process.
BHA sag management service description
Survey error correction has a major impact on the wellbore placement. DrillScan BHA Sag Management service proposes, at all stage of the well life, to correct the inclination and azimuth of actual survey stations, based on the misalignment of the wellbore survey tools due to BHA deflection.
BHA Sag error, existing on every BHA, induce wellbore survey error occurring at each survey station, leading to significant wellbore misplacement in the final surveyed wellbore trajectory. Our service can guide the pre-well engineering process to anticipate TVD corrections. We are also able to perform while-drilling monitoring of wellbore positioning, enhancing collision avoidance process and target intersection success. Post-well sag analysis can be performed to update a wellbore trajectory database, or to obtain a precise wellbore trajectory of some critical wells.
