COILED TUBING CONVEYANCE OF WELL FLUIDS TO SURFACE
Availability of CT as well known OCTG and the need to have new options on artificial lift prompted a CT consulting firm to investigate the use of CT to convey well fluids to the surface. While numerous test proved that CT as "hollow sucker rods" can replace conventional sucker rods and production tubing, the lack of appropriated coil tubing units to deploy and retrieve CT economically delays the application of this innovative option. The paper will discuss new CTU designs and economics related to the use of CT versus solid sucker rods, and the latest developments in artificial lift with coiled tubing. This paper will describe laboratory testing, field application methods and case history results of the application of salt inhibiting treatments in several applications.
