Wellbore Survey

–Background

•Recently, technology have advanced in such away that the former directional drilling tools were replaced with an advanced ones such as:

–Steerable mud motors,

–MWD,

–Andergauge Stabilizers,

–LWD.

•These tools, in combination, could provide  a 3D well profiles without changing BHA and have enabled the drilling of horizontal and multi lateral wells.
