Gre composite material for well completion solution

The Glass Reinforced Epoxy Liner has been applied successfully in several Eni fields, onshore and offshore, as corrosion protection in oil production and water injection well tubings and in surface gathering lines. The feedbacks from fields demonstrate that when used within the operating limits this material represents a valid option for life extension and allows achieving a life-cycle cost saving.
The two tests verified the erosional resistance of GRE material with regard to its suitability for use in high velocity gas wells in very challenging conditions. The testing conditions simulated the actual wells environment in terms of sand production and confirmed that GRE has the effective erosional properties needed. The economics of using GRE is well documented and further highlights the materials potential for cost savings over high grade corrosion resistant alloys in suitable Gas Production and Injection wells.
