Glass Fibre reinforced Epoxy Casing System for Geothermal Application
GRE-GEO
Call 2 2019
The fluid composition in geothermal projects contains multiple elements that accelerate corrosion and induce scaling, significantly reducing the lifespan of traditional steel casing systems, which must ensure wellbore integrity. Consequently, workover procedures are required earlier than expected, becoming a substantial financial burden. In contrast, due to their corrosion resistance, glass fiber casings (GRE) offer a desirable alternative. However, compared to steel, GRE pipes are currently available only in relatively small inner diameters with excessively large outer diameters. This limits their handling and installation according to oil and gas standards originally developed for steel. The lack of a suitable alternative to steel jeopardizes the profitability of geothermal projects facing massive corrosion problems.
The main objective of this project is to develop cost-effective glass-fiber-reinforced epoxy piping (GRE-GEO) specifically designed for geothermal well applications, featuring a relatively large inside diameter and smaller outside diameter. This includes the pipe coupling, allowing installation in new wells and utilization for workover of old wells. Additionally, the project will provide essential guidelines and tools for designing, qualifying, and installing the GRE piping system, accelerating its market integration. Improvements in well completion technology and materials offer significant advantages over steel-based systems. High corrosion resistance significantly prolongs the overall lifespan of the wellbore compared to conventional steel casing designs by integrating a safety barrier that guarantees wellbore integrity.
