Title: Use of stress cycling to remove downhole scale from geothermal wells using coiled tubing

Conference ·
OSTI ID:602650

This paper describes the first application of a relatively new oil field technology to the geothermal industry. The technology is referred to as stress cycling and provides a method of removing hard deposits, such as silica or calcium scales, from tubulars using only jetting action. This new technology lends itself to coiled tubing operations and results in a very fast and efficient clean out operation. The paper describes the theory of stress cycling and lists the operational procedure used on the first job attempted on a geothermal well. The results of the operation are included.
