Abstract
A bundle of spoolable power supplying and heating cables and at least one weight-supporting strand for forming an assembly for electrically heating or heating and logging a long interval of subterranean earth formations is installed within a well by spooling superposed flat layers of those strands and an interspersed flexible band on a drum substantially as narrow as the layers, while interconnecting the power supplying and heating cables on the drum, and then unspooling the strands into the well while intermittently banding them into bundles and concurrently respooling the flexible band on a different drum.
