Sustainability of the Bacman Geothermal Field

Abstract

Results of the geochemical monitoring of the field for the last ten years showed that most production wells have attained a relatively stable chemical discharge with time. There was also an absence of detrimental reservoir processes as experienced in other PNOC-EDC geothermal fields such as injection returns, cold ground water intrusions and acidic inflows. Most often, reservoir related problems encountered occur near well bore and at very manageable levels. This paper aims to present that the current reservoir management strategy and with the existing geochemical monitoring scheme all point out to a stable and sustainable resource.
