High-fidelity trajectory estimation combined with dual-probe Measurement-While-Drilling (MWD) directional instrumentation provides a solution to minimum curvature’s known inefficiencies in modeling the true wellbore position and definition (Stockha

It has been well documented that magnetic models and Measurement-while-Drilling (MWD) directional sensors are not free from error. It is for this reason that directional surveys are accompanied by an error model that is used to generate an ellipse of

Passive magnetic ranging (PMR) is a technique used to determine the range and direction to a cased well that may not be accessible during the drilling of an adjacent well. It has been used since the 1970s (wireline) in relief wells and anti-collision

The authors are concerned that the claim of increased accuracy for MWD directional surveys processed using multistation analysis (MSA) may not always be valid, resulting in incorrect assumptions regarding the probability of well collision and target
