Abstract
A technique provides a drilling system and method in which a drilling assembly is delivered downhole on coiled tubing. The drilling assembly comprises a drill bit and a motor to rotate the drill bit for drilling of a borehole. A steerable system is used to steer the drill bit, thereby enabling formation of deviated boreholes.
