Abstract
Apparatus and method for drilling a drain hole from a well are provided. A flexible tubing used for conveying fluid to a jet bit is confined radially by a reduced-diameter tubing piece or a liner in production tubing near the diverter used to direct the flexible tubing. Concentric tubing pieces allow location of the bit in a well by measuring weight of a work string.
