Abstract
Injection of steam condensate back into the Geysers reservoir produces shifts in the chemistry of produced steam at nearby wells. Specifically, these effects include: 1) changes in the spacial variation of noncondensable gas/steam ratio; 2) changes in the concentrations of stable isotopes O and deuterium; 3) shifts in the abundance of gas species Ar, N2, and NH3 and 4) changes in calculated gas geothermometers and steam saturation factors. This geochemical information, when combined with other reservoir data, has been used to assist in the targeting of new injection wells.
