Abstract
Curtailment tests were conducted at the Calistoga and Bear Canyon wellfields from March to June 2001. The curtailments are found to result in lower decline rates as well as in an increased steam flow rate following the curtailed period. This increase is referred to as a "puff" and its duration is proportional to the extent of curtailments. The data from these tests have been used to develop a relationship between curtailments and the puff. A plot of annual curtailments versus annual decline rate for the Bear Canyon wellfield from 1991 to 2000 supports the contention that the decline rate decreases with increasing curtailments.
