Geothermal ScientistLihir Gold Limited Nov 2006 - Nov 2008Geothermal Scientist reporting to the Geothermal Coordinator /Superintendent, responsibilities include but not limited to ensuring that geothermal data is gathered and interpreted in order to provide advice for safe mining operations and to sustain steam supply for the geothermal power plant. These objectives are achieved in coordination with Geotechnical, Mine Geology, Mine Operations and Drilling/Pumping groups as necessary.Key elements of the role include:• Lead the team responsible for depressurization of the pit before safe mining is permitted. This requires collection of temperature data from all blastholes and collating that with known trends in the pit to determine temperature regimes and recommend blasting practices. • Provide direction to the contractor in undertaking downhole measurements of pressure, temperature and flow rate in geothermal wells.• Supervise the contractor and take a leading role in conducting bore output tests and geochemical fluid sampling in geothermal wells.• Collate all recorded data onto geothermal database and ensure all data entries are accurate.• Develop and implement monitoring program for all geothermal wells and natural thermal surface features to monitor significant change in geothermal activity and recommend appropriate advice to mining operations• Coordinate with the Geotechnical, Mine Geology and Drilling/Pumping Sections in monitoring and assessing the geothermal resource.
