Abstract
A fiber optic instrumentation line is introduced down a hydrocarbon (oil) well bore by control line formed by pressure tubing conduit fixed on the outside of intermediate casing and set in cement slurry between casing and surrounding rock and reaching to the hydrocarbon production zone . Hollow primary member accepts distal end of control line at the end of casing . Secondary member having sealed terminal control line on its outer surface is lowered through primary member to zone , automatically angularly aligning and engaging respective top and bottom end couplings and , sealing together a respective top and end of terminal control lines forming a continuous, high pressure, fiber optic receiving tube, from well head to well bottom. Alternatively, two lines linked by loop provide a continuous control line returning to the surface.
