Abstract:
An improved method of drilling a substantially lateral section of a wellbore is provided. A first segment of a drilling string with a bottom hole assembly is extended into a wellbore. At determined intervals of the drilling string, a plurality of friction reduction segments are connected as the wellbore is drilled and the drilling string is extended into the wellbore. The friction reduction segments comprise a friction reduction tool and corresponding activation tool for activating the friction reduction tool. The activation tool selectively diverts drilling fluid into a motor powering the friction reduction tool or away from the motor, and can be a ball catch assembly that is activated when a suitably sized projectile is seated in the assembly. Multiple friction reduction segments can be connected to the drilling string and one or more of the plurality of segments can be activated.

Claim (Index 1):
A method of drilling a substantially lateral section of a wellbore using a drilling string, the wellbore comprising a substantially vertical section and a build section connecting the substantially vertical wellbore section and the substantially lateral section, the method comprising:\n providing a first segment of the drilling string having drill pipe connected thereto, the first segment comprising a bottom hole assembly; at a first determined interval of drill pipe connected to the first segment, connecting a first friction reduction tool and a first activation tool, the first activation tool being in operable communication with the first friction reduction tool for activating the first friction reduction tool, the first friction reduction tool and the first activation tool providing a first friction reduction segment; connecting further components of the drilling string above the first friction reduction segment; drilling a portion of the substantially lateral section of the wellbore using the drilling string while the first friction reduction tool is not activated; at a further determined interval of the drilling string above the first friction reduction segment, connecting a further friction reduction tool and a further activation tool to the drilling string to provide a further friction reduction segment, and connecting further components of the drilling string above the further friction reduction segment; drilling a further portion of the substantially lateral section of the wellbore using the drilling string while the first friction reduction tool and the second friction reduction tool are not activated; activating the first friction reduction tool using the first activation tool while at least the first friction reduction tool is positioned in the substantially lateral section of the wellbore; and drilling still a further portion of the substantially lateral section of the wellbore using the drilling string while the first friction reduction tool is activated and the second friction reduction tool is not activated.
