ABSTRACT:
A system which may be used to replace workover rigs and metallic pipes for the production of hydrocarbon from wellbores uses a non-metallic, substantially continuous, flexible tube comprising a flexible, non-metallic, e.g. resin-based, substantially continuous production tube that can be wellbore deployed and retrieved without the need of onsite rigs. The system's components can be placed inside existing pipes for work in old wells where removal of the existing tube is not economical. The tubes may also be spoolable, thereby increasing installation rates and flexibility. Connectors for the tube may be dimensioned and configured to allow for providing and/or sealing downhole tools to the production tube. In certain embodiments, an onsite power generator will provide a clean alternative to existing diesel burning generators and will typically use a furnace, boiler, steam engine and electrical power generator.
