Problem Well Solved
A customer in SE Saskatchewan, Canada shared this story:
Situation:
From 1984 to 1998 the well required 24 service rig jobs. Sixteen of the 24 were tubing leaks. The other 8 were parted rods due to wear. That works out to a tubing leak every 10.5 months and in total service rig was on location every 7 months. The client mapped out the locations of the tubing leaks and found that they all occurred in two areas. The majority of the leaks were in the 20 joints above the Pump Seating Nipple, joints 129 to 110, with the remainder of the leaks between joints 80 and 87.
Action:
EndurAlloyTM tubing was run in this well as follows: Joints 1-79 – regular tubing, Joints 80-87 – EndurAlloyTM tubing, Joints 88-109 – regular tubing, Joints 110-129 – EndurAlloyTM tubing. The client also ran 60 rods with three-per-rod, molded-on, wide vane, tapered centralizers above the pump to further reduce rod and tubing wear.
Result:
To date the well has run 17 months with no problems and is still running. The EndurAlloyTM tubing has saved them at least 2 well servicing jobs in the past 17 months. It has probably saved $30,000 due to decreased failures.
