THE CHALLENGE:
To provide superior internal corrosion protection using a Glass-Reinforced-Epoxy (GRE) lining system with any unmodified free-issue premium threaded tubing or casing.
THE SOLUTION: IN TWO EFFECTIVE STEPS:
1. Use DUOLINE® from Duoline Technologies: a premium internal corrosion resistant lining system for oilfield steel tubing and line pipe. DUOLINE® is proven to be wireline abrasion and chemically corrosion resistant in both controlled laboratory testing and through successful performance in more than 75,000,000 feet of downhole application.
2. Use Duoline Technologies new DL-RING patent pending connection technology that permits the lining system to accommodate any proprietary Premium Connection.
HOW DOES THE DL-RING WORK?
Two DL-flares place the DL-CBR in compression during field make-up.
The unique concept and material composition has been used extensively and successfully in downhole completions with DUOLINE® tubing in numerous other 'FGL' versions of unmodified premium and API connections.
