Design and Safety Considerations for Coiled Tubing Operations in Geothermal Wells
This paper’s authors describe the development of a coiled tubing (CT) nitrogen-lift design in which CT and geothermal reservoir simulations were combined to overcome modeling limitations.
The productive section in a high-pressure, high-temperature (HP/HT) geothermal Field A in the Philippines features shallow and deep reservoirs separated by a low-permeability formation. However, recent years have seen a reduction in production levels. To activate and enhance well production, coiled tubing (CT) nitrogen-lift operations were required. CT simulations were combined with simulations from the geothermal reservoir to overcome modeling limitations.
