  • Well hot oil system
    Patent number: 4609041
    Abstract: The invention pertains to the removal of paraffin deposits from oil producing wells wherein hot fluids are used to melt the deposits. A conduit system consisting of tubing concentric to the well tube carries hot oil to the well tube at a location below the paraffin forming depth. Ports within the well tube permit the hot oil to enter the well tube during pumping, and the heated oil and melted paraffin is removed at the well head without interrupting pumping. A check valve within the hot oil conduit prevents pumped oil from entering the conduit and the apparatus permits paraffin to be removed from an oil well in less time and with less cost than previous paraffin removal systems, without interrupting pumping, and without contamination of the oil bearing formation.

  • Power-assisted coupling
    Patent number: 4592387
    Abstract: A manually operated, power-assisted, self-sealing fluid coupling which utilizes pressurized fluid to interconnect the coupling parts. A sleeve within one part selectively locks to the other part and utilizes an expansible chamber motor to draw the other part into the one coupling part, and a second expansible chamber motor associated with the sleeve neutralizes the coupling force of the first motor during disconnection and manual operation of the sleeve through a valve component disconnects the coupling parts.
