RESULTS. 6.1. Field Wide Results During Period-1 (1960-1969), average production rates and average pressures are fluctuating immensely. This is the result of many new xxxxx initially shut-in (i.e., pressure increases), but later brought into production (i.e., sudden pressure drop) when a new power plant comes on line. During Period-2 (1970-1986), most of the field development is complete and a relatively steady steam production and injection is maintained. Some fluctuation of pressures is visible as a result of well-throttling (Xxxxxx and Pingol, 1997). During Period-3 (0987-1996), production and pressure have the steadiest decline, because the majority of the xxxxx are producing at open valve conditions. Throughout the 48-year history of the field, this may be the most stable condition, and hence the most suitable period for decline-curve fitting. Period-4 (1995-2008) is characterized by huge changes. During the xxxxxxx of 1995-1997, major production curtailments resulted from sale-agreement conditions. By September 1997, mass replacement increased to about 55% as the Lake County pipeline began operation (Figures 3 and 4). By December 2003, mass replacement increased to about 80% as additional water was being injected from the Santa Xxxx pipeline. Since 1998, the production rate per well has remained almost constant, while the pressure decline has remained unchanged. This “additional” production is attributed to the additional injection. 6.2.
