Abstract: A coiled tubing transfer system comprising a carrier having a bed, the bed having a width and the length, the length of the bed being longer than the width of the bed, a reel removably supported on the bed, the reel comprising a spool rotatably journaled in first and second supports, the spool having a core with a diameter and long axis extending between the supports, the long axis having a length greater than the width of the bed, the reel being positionable on the bed in a first position with the long axis of the core extending lengthwise of the bed, the longest dimension of the reel transverse to the long axis of the core being less than the width of the bed and a length of coiled tubing useable in earth borehole operations being wound around the core, the coiled tubing having an outside diameter of from 1? to 9?, the ratio of the diameter of the coiled tubing to the diameter of the core being from 1:20 to 1:70.

Abstract: A method and apparatus for conducting earth borehole operations include a reel (28) of continuous coiled casing (30), and an injector (20) for moving the coiled casing. The bottomhole assembly including at least a motor (54) and a bit (56) is connected to the free end of the coiled casing, and injected into the earth while circulating fluid through the coiled casing to form a drilled earth borehole having a borehole wall. The coiled casing drill string may be retrieved from the borehole, the bottomhole assembly removed, and the coiled casing again injected into the borehole, then suspended from a wellhead assembly. After severing the coiled casing, a bonding agent such as a cementitious material may be injected into the suspended coiled casing and into the annulus between the coiled casing and the borehole.
