Abstract: Device combinations and methods for wellbore operations for simplifying production methods and workover operations and for production from a failed secondary zone. Using a commercially available prior art coil tubing unit, a coil tubing string is run into an already-in-place production tubing string. The coil tubing string has a commercially available prior art sand control device at the bottom, a portion of blank pipe and a commercially available prior art releasable hydraulic running and release tool ("hrart"). A commercially available prior art small washpipe is connected to the hrart. Wash fluid flows through the hrart, to the wash pipe, and then out of the washpipe thereby washing the sand control device into place in filter media at the perforated production zone. An isolation packer or packers are set between the production tubing and coil tubing string.
