“NEW” Super Life 575 Polymer Packing Case Study
A case study was conducted using the new WSI Super Life 575 Polymer packing on a well in Southern Oklahoma. The well produced 5 barrels of oil and 341 barrels of water per day, representing approximately a 1% oil cut. Below is the well data information:
- Packing Installed: 07/07/2014
- Packing Replaced: 02/18/2015
- Run Time: 226 days
- Prior Packing: Standard Soft Cone packing replaced every 18 to 21 days
- Maximum Pressure: 120 PSI
- Strokes Per Minute: 6.81
- Stroke Length: 144 inches
- Operating Time: 18 hours per day
Summary: The WSI Super Life 575 Polymer packing experienced more than 86,953 feet of polished rod movement per day. This equates to a 1000% increase in service life over the previous packing.
A second case study with similar run times was also conducted using the new WSI Super Life 575 Polymer packing on several wells in Drayton Valley, Canada. On average, the Super Life 575 Polymer packing lasted seven times longer than the previous packing materials, including:
- Teflon
- Hard
- High Temp Brass
While all well conditions were not provided by the customer, it is known that wells in this area contained up to 2% H2S, with well pressures up to 500 PSI and temperatures up to 175°F. Strokes per minute ranged from 5 to 7 SPM with a 120-inch stroke length.
