ABSTRACT:
A method and apparatus for drilling and/or working in a drainhole wellbore which extends laterally from a primary wellbore which utilizes flexible hose which can be deployed into the primary wellbore and recovered from the primary wellbore in a coiled fashion, and uses apparatus for coiling, deploying and recovering the flexible hose which includes a rotatable drum operatively connected with a movable beam and guide means. The beam and guide means are utilized to position the flexible hose over the primary wellbore in such a manner that essentially only vertical external forces and essentially no lateral external forces are applied to the apparatus thereby eliminating the need to rigidly fix the apparatus to the earth or other support means when in use.
