摘要
A system and method to facilitate the drilling of one or more lateral wellbores while eliminating one or more trips downhole. The system utilizes a drilling assembly comprising an impregnated drill bit or other suitable drill bit.

The connector comprises a separation device which facilitates disconnection of the impregnated drill bit from the whipstock once the whipstock is anchored at a desired downhole location.
