Abstract
The invention is a method for drilling a well and for well intervention using a multipurpose system on a pivoting, slidable cantilever on a platform to drill a well and to perform well intervention operations, wherein the method involves pulling a completion tubing out of the well; forming completion tubing segments pulled from the well; setting back the segments into a storage area; running the coiled tubulars into the well; removing used completion equipment from the well; preparing the well for new completion equipment with the coiled tubulars; pulling segments of new completion tubing from the storage area and breaking segments of new completion tubing into individual joints and removing the individual joints from the cantilever; running into the well with coiled tubulars and installing the new completion equipment; building segments from individual joints and setting the segments in the storage area; and running segments and new completion equipment into the well.
