Wang Drilling new production wells in older, established fields may collide with / / existing wells. Control of new wellbore traj ectory is a key problem in clu ster / drilling technology. Directional drilling from platforms or well pads necessitates drilling close to existing wells. Risk s associated with closely spaced drillings are generally mitigated u sing gyro or other directional survey data to establish Landmark fixed well separation guidelines.
