Abstract
This paper presents measurements made in the bore of a well at Te Aroha in the North Island of New Zealand, and their interpretation. The well produces hot water and CO2 from a production zone at a temperature of about 90?C, and discharges periodically like a geyser. Temperature surveys and pressure measurements at fixed depths have been made, allowing the determination of mean density and void fraction in the wellbore flow, leading to an understanding of the flow processes that govern the cyclic discharge.
