Abstract
Cementing of geothermal wells is of special interest due to the associated high temperature corrosive fluids and fragile formations. Systems used for cementing conventional oil and gas wells are not necessarily suitable in harsh geothermal environments and can lead to cement failure and costly blowouts. The research program documents here consists of two phases. (1) definition of problem/determination of requirements and (2) development of a cement system which will function effectively over long periods of time at the specified conditions. This paper reports work performed to date concerning the second phase.
