ABSTRACT:
The present invention involves a method and apparatus for communicating from within a wellbore to the surface of the wellbore, as well as communicating from the surface of the wellbore to downhole within the wellbore. More specifically, the present invention involves a method and apparatus for protecting and controlling cables or lines which connect surface equipment to downhole equipment. A spacer sub comprising a tubular body with a helical groove therearound is used to house one or more downhole cables. In one aspect, the spacer sub has a recess within the helical groove for housing one or more cable connectors. In another aspect, multiple helical grooves are disposed around the spacer sub to protect and house cables of different length.
