MAP Oil Tools

Model PCU-1 Upstrain Unloader is designed to equalize tubing and annulus pressures above a PC-1 Retrievable Cementer Packer or other makes of upstrain actuated tools that are compatible in operation with that of the Unloader.

The Unloader is made up directly above the PC-1 Cementer Packer and is usually run in the hole in the open position to allow fluid bypass through PC-1 and into the annulus. Torque is transmitted through the unloader to the PC-1 by a key located in a key-slot of the unloader body. Applying upstrain to set the PC-1 will close the Unloader and setting down weight will open it.

  • Unloads pressures from either direction
  • Multiple acting, May be run in either open of closed position and then opened to closed as many times as required
  • Full opening bore through tool
  • Easy operation, Set down weight to open and apply upstrain to close
