Abstract:
A method of drilling a substantially lateral section of a wellbore includes extension of 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 drilling method, comprising:\n drilling a portion of a wellbore using a drilling string comprising a bottom hole assembly and an active friction reduction tool connected to the drilling string at a first interval above the bottom hole assembly; connecting a second friction reduction tool to the drilling string at a second interval above the first friction reduction tool, wherein the second friction reduction tool comprises a variable choke assembly having a rotary component and a stationary component, and an oscillating unit,\n each of the rotary component and stationary component being provided with passages that enter into and out of alignment when the rotary component rotates with respect to the stationary component, the rotary component being drivable by a rotor of a motor of the second friction reduction tool; \n the rotary component, stationary component, and rotor each comprising a central bore defining a central passage permitting drilling fluid flow from above the second friction reduction tool to below the second friction reduction tool; \n activating the second friction reduction tool in the drilling string while the active friction reduction tool is active, wherein activating the second friction reduction tool comprises:\n blocking the drilling fluid flow through the central passage with a projectile to divert the drilling fluid flow through the motor to thereby activate the rotor and drive the rotary component, wherein at least some fluid enters the passages of the rotary and stationary components as the rotary component rotates, thereby producing fluid pressure pulses to activate the oscillating unit.
