Flexible cable rod equipment set is used for oil production from horizontal wells or rat holes with casing of small diameter and drift angle up to 90 degrees. Equipment set consists of sucker rod string, flexible cable rod, crossover coupling, specialized sucker rod pump SPeaR and slot filter. Usage of cable at the interval of intense drift deviation allows avoiding friction between tubing string and rods due to less friction force.
Flexible cable rod set increases pump setting depth in sidetrack and provides additional oil production.
SPeaR pump with plate valves provides operation in wells with highly viscous oil, deviated wells up to 90° and sidetracks. It is also widely used in combination with flexible cable rod for highly deviated wells.
SRP with KTC hemisphere valves provides oil production in wells with deviation angle up to 70 degrees and high viscosity oil.
