Engineering tubular solutions for geothermal wells
Geothermal has proven potential as a clean energy source that can be accessed 24/7. Geothermal energy can be used distributed through turbines for power generation, or feed directly into district cooling or heating systems. However, the investment required to drill geothermal wells is high, and operators have traditionally offset these costs by using basic tubulars. This approach can be insufficient, and a potentially risky choice for operators in the long-term. Since geothermal wells are meant to operate for decades at a time, their tubulars must be able to consistently withstand a harsh environment. Choosing the right tubular solutions is critical to ensuring resistance to corrosion, erosion, changing temperature cycles and more, and can help owners optimize the costs of their geothermal assets.

Our Role in Geothermal Energy
VAM® 21 has once again gone beyond standard applications to meet the requirements needed to extract hot fluid from geothermal wells. The premium connection was recently installed in two of Geo Dipa Energi’s geothermal wells in the Dieng Plateau in Indonesia withstanding temperatures of up to 330°C.
“We are very satisfied with the results obtained with VAM® 21 in our Dieng well, VAM® 21 was ran quickly and efficiently with zero rejects.”
