Abstract |
In an attempt to address the imminent needs for high temperature instrumentation to be used in a deep geothermal drilling project in Iceland (IDDP - the Iceland Deep Drilling Project), a successful application was submitted to the European Union within the Union's 6th framework programme. The purpose of the ongoing project, named HiTI (High Temperature Instruments for supercritical geothermal reservoir characterisation and exploitation), is to allow crucial physical parameters to be evaluated in geothermal wells at temperatures and pressures up to and beyond the well fluid’s supercritical state (T>374 °C and 22 MPa for pure water). In cooperation with Oxford Applied Technology (partner in HiTI and HITEN), the intention is to identify the requirements of high temperature electronics to be used for both long- and short term monitoring in high temperature geothermal reservoirs, at conditions that are currently beyond the limit of commercial electronic circuits. |
