Abstract
This paper describes the uncertainties associated with determining an appropriate dip to geosteer a well towards the landing zone and along the well trajectory, and how a 2D VSP helped. Various methods of pre-drill dip estimation are discussed and compared to the 2D VSP and to LWD measurements.
