Abstract
058457102 A method of completing a subterranean well and associated apparatus therefor provide efficient operation and convenience in completions where production of fluids from a lateral wellbore and a parent wellbore is desired. In one disclosed embodiment, the invention provides an efficient method of protecting a junction of multiple wellbore portions by positioning a tubular drilling guide within the well extending through the junction. In one aspect of the present invention, the drilling guide is sealingly engaged with certain ones of the wellbore portions while drilling operations are being performed.
