WIRELINE PARAFFIN REMOVAL &
“PARAFFIN PREDATOR” DEPLOYMENT on Flowing Well

1. E-LINE PARAFFIN REMOVAL USING THE WELLS “HOTROD”

  • Move in and rig up E-Line with 5K lubricator under Crane/Mast and HotRod with brass skirt sized >Locking Device and
  • Surface Test the HotRod on E-Line (tool should immediately be warm to the touch)
  • Make-up lubricator on the well and pressure test before opening the well
  • Begin lowering the HotRod to engage the paraffin solids
  • Flow the well back through a choke to remove the paraffin granules
  • Using a “Yo-yo” technique gradually move downhole until all paraffin has been removed (process generally takes 1.5 – 3 hours)
  • Monitor flowback to insure all paraffin has been removed
  • Pull out of hole and rig up junk basket/Gauge ring >Locking device and

2. PARAFFIN PREDATOR DEPLOYMENT USING SLICKLINE (PREFERRED METHOD) OR E-LINE

  • Rig attach OTIS setting equipment, locking device and Paraffin Predator to wireline
  • Run in hole and set Paraffin Predator in prescribed seat nipple
  • Retrieve setting equipment
  • Establish flow-rate
  • Rig-down wireline

3. INFORMATION NEEDED BEFORE JOB

  • Flow-rate
  • Total production in bbls/day
  • MCF/day
  • Bottom hole temperature
  • Profile nipple information
  • Pipe drift/Minimum restriction
  • Well head connection
  • H2S Content
  • Asphaltine Content

4. APPLICATION

  • This process will be most applicable on flowing wells.
  • The deployment procedure is currently performed with E-line off a crane truck.
  • A combo unit (slickline/E-line) with a mast is being designed specifically for this procedure in order to create the most economical and efficient application.
  • The “HotRod” can be used in any well with a standing column of fluid
