INDRIVE  introduces PCPOS - User Friendly Windows Based Software to keep your PCP system completely automated and operating at top performance.





The most valuable information about an operating oil well is the dynamic pumping fluid level. For a sucker rod driven PCP artificial lift system it has been shown that there is a

direct relationship between dynamic fluid level and the axial load exerted on the drive head thrust bearing. This axial load can be measured by a load cell on the PCP drive head. PCPOS uses the axial load as the main control variable along with surface tubing pressure, surface casing pressure, motor current and torque to create an expert system to automate and optimize the PC pumping unit. No down hole sensors are required. PCPOS can automate and optimize single wells or multiple wells.
