Methods and apparatus for rotating a stripper assembly in use with a rotating drilling head. A drive system is disposed external to the rotating drilling head and generates rotational motion to match the rotation of a drillstring running through the rotating drilling head. A connection transfers rotational motion from the drive system to the stripper assembly. In one embodiment, the drive system comprises a housing disposed about the drillstring and a one or more contact members connected to said housing and operable to contact the drillstring. One or more biasing members urge the contact members into contact with the drillstring so as to transfer rotational motion from the drillstring to the housing.

A method for maintaining pressure in a wellbore during drilling operations includes the steps of providing fluid from a reservoir through a drill string, circulating the fluid from the drill string to an annulus between the drill string and the wellbore, isolating pressure in the annulus, measuring pressure in the annulus, calculating a set point backpressure, applying back pressure to the annulus based on the set point back pressure, diverting fluid from the annulus to a controllable choke, controllably bleeding off pressurized fluid from the annulus, separating solids from the fluid, and directing the fluid back to the reservoir. An apparatus for maintaining pressure in a wellbore during drilling operations includes an adjustable choke for controllably bleeding off pressurized fluid from the wellbore annulus, a backpressure pump for applying a calculated set point backpressure, and a processor for controlling the adjustable choke and backpressure pump.

A reamer used in earth boring by the rotary method includes a body having a plurality of sockets in its outer periphery. Upper and lower blocks are disposed in the socket for supporting a shaft. A roller is rotatably mounted on the shaft with the inner periphery of the roller and the outer periphery of the shaft providing bearings for the roller. The shaft has an upper annular shoulder with a downwardly facing sealing surface disposed above the bearings. Upper and lower seals are disposed above and below the bearings with the upper seals having a facing seal sealingly engaging the roller and the downwardly facing sealing surface on the shoulder of the shaft.
