Anti-Collision Considerations for Arctic and Other High Latitude Locations

Abstract: A significant contribution that some oilfield services companies provide for drilling operators today is directional well planning. A major task in the process is to identify and analyze the risk of wellbore collisions. If there is a risk of collision beyond acceptable limits, risk management must be applied. The first part of this process is to collect data. The second step is to analyze the potential risk. The risk not only involves a financial aspect but also HSE (Health Safety and Environmental), so it is … Show more

“…Drilling at this relatively small separation and deep measured depth increases the risk of collision, so all MWD surveys recorded after the gyro in surface were processed to remove error sources, including magnetic disturbance field, sensor sag, and internal drillstring interference (Chatar et al, 2015). The laterals drilled in parallel with offsets at a distance much greater than where magnetic interference on the MWD surveys were expected for offset casing, which is generally observed until a separation of up to 30 ft.…”
