Successful Well Design and Remedial Cementing by Top Squeeze Method at Steamboat, NV, USA

Ormat drilled well 42A-32 in the Steamboat field in 2018 to support injection at its Steamboat complex. Injection well 42A-32 was drilled to replace existing injection well 42-32 in the Steamboat field. Geologic conditions present at the well location include an unconfined NCG (non-condensible gas) entrained steamzone above a highly fractured and permeable reservoir. Well 42-32 had issues with lost circulation, lack of cement returns on the intermediate casing string, and later during its operating life, the well had cement and casing corrosion requiring multiple scab liners. As a result, the well operated for less than 10 years.
