Directional Surveying

Abstract

The objective of this document is to provide technical requirements for activities related to directional surveying. The main objectives can be summarized: - Estimate wellbore position and uncertainties - Ensure compliance between actual and planned well trajectories - Position well trajectory within given geological target tolerances - Avoid wellbore collisions - Define accurate targets for potential future relief wells - Facilitate structural, stratigraphic and rock property mapping - Minimize the uncertainty of wellbore positions with regards to future wells
