doesn 39 t tend to helix within the wellbore also because corod has material across a substantial portion of its cross section it retains relatively high tensile and compressive strength under axial loading as well as internal or external differential pressure corod is superior to jointed pipe because it can be deployed using a more cost effective and logistically versatile system and in a more time efficient manner the corod string works equally well in vertical and highly deviated wells the corod can be used for multiple runs into a well or wells with no fatigue because unlike coiled tubing it is not plastically deformed when cycled on and off the reel the corod string can be run through tubing thereby eliminating the additional cost and time required to deploy a jointed pipe or tractor conveyed systems it is also noteworthy that the corod string for conveying equipment is not limited to oil and gas well applications it is equally applicable to use in a pipeline where pipeline inspection services are run to better understand the novelty of the apparatus of the present invention and the methods of use thereof reference is hereafter made to the accompanying drawings fig1 is a sectional view illustrating a corod string 100 positioned in a wellbore 10 as shown the wellbore 10 is lined with a string of casing 15 the casing 15 provides support to the wellbore 10 and facilitates the isolation of certain areas of the wellbore adjacent hydrocarbon bearing formations for purposes of discussion the wellbore 10 is illustrated as a deviated wellbore it should be understood however that the corod string 100 may be employed in a vertical wellbore without departing from principles of the.
