A system can include a tubular string with a drilling bottom hole assembly connected at a distal end of a coiled tubing including a communication line permitting communication between surface instrumentation and the drilling bottom hole assembly, and the drilling bottom hole assembly including an orienter and ranging equipment. The tubular string is positioned in an intercept wellbore which intersects a target wellbore downhole of an obstruction that prevents access to the target wellbore downhole of the obstruction. A method can include drilling an intercept wellbore outward from an original wellbore, after an obstruction is introduced between the original wellbore and a target wellbore, and intersecting the target wellbore with the intercept wellbore, so that fluid communication is provided between the intercept and target wellbores.

Accessing wells below an obstruction or discontinuity

A system for use with a subterranean well can include a bottom hole assembly connected at a distal end of a tubing section, and another bottom hole assembly connected between the tubing section and another tubing section that comprises continuous coiled tubing. A method of performing a well operation can include deploying a tubular string into a wellbore, the tubular string comprising multiple tubing sections, a bottom hole assembly connected at a distal end of one of the tubing sections, and another bottom hole assembly connected between two tubing sections. An uphole tubing section comprises continuous coiled tubing. The tubular string is retrieved from the wellbore. The deploying and the retrieving are performed in a single trip of the tubular string into the wellbore.
