ABSTRACT:
The present invention relates to composite material structures having reduced signal attenuation properties. In particular, the invention relates to composite drillstring components with electromagnetic properties and acoustic properties that enable the use of electromagnetic, acoustic and nuclear sensing equipment to obtain data from a wellbore from within a drill pipe. In a specific embodiment, a composite tube is incorporated with end-fittings which enable its incorporation into a drillstring thereby permitting the use of logging equipment from within the composite tube.
