Geothermal Well Cementing, Materials and Placement

2017-11-14  Geothermal wells are cemented using many of the same techniques as in the oil and gas industry. However, high temperatures, corrosive brines and carbon dioxide severely challenge the long-term durability of well cements. Well cementing is a critical part of well construction and requires a dedicated design and engineering process.

Geothermal Wells – Crucial Problems in Cementing

Cementing in high temperature environments such as geothermal wells is very challenging. The survey that was sent to High-Pressure-High-Temperature (HPHT) professionals at the HPHT Summit meeting in 2012, showed Cement Design is one of the biggest concerns for HPHT operations and it is one of their technology gaps.

Abstract. Cementing deep, high-temperature oil wells where static temperatures range from 350 to 400F has become routine in the past decade. In the United States there were 271 wells drilled deeper than 15,000 ft during 1963. Many of these wells had static temperatures higher than 400F. Bottom-hole static temperatures near 700F are now realities in the geothermal (steam
