Abstract: Some system embodiments include: a casing string having a distal end with a latch assembly; and a drillstring latched within the casing string by the latch assembly, the drillstring having at least one tool for perforation and stimulation. A pressure while drilling tool and one or more packers may be provided in the drillstring to further enable the stimulation operation. Prior to perforation, the casing string is cemented in place via a cement valve, and the drillstring is unlatched and raised to the desired completion position. The perforation and stimulation process can be repeated to provide multiple completions. The drillstring can be removed from the borehole or seated in place to control production. Logging instruments can be included for steering and/or use in making completion decisions.
