Research Team PT Geo Dipa Energi of the Faculty of Mathematics and Natural Sciences (FMIPA) at Gadjah Mada University (UGM ) and New Zealand-based Geo Flow Imaging Ltd. have signed a Memorandum of Understanding for the Demonstration of Proof of Concept. The field of a new seismic research technology for geothermal exploration has been created. The technology developed by Geo Flow Imaging is adapted from the principles established in shale formation excitation monitoring. It relies on downhole seismic welding using a chemically inert, heat-resistant, fast-burning propellant that emits seismic waves at subsonic speeds through the downhole. A surface seismic array measures the seismic velocity structure, thus providing data for constructing a local crustal velocity model.
This technique aims to provide more accurate modeling for good targeting, thereby helping to reduce exploration costs and make geothermal projects more commercially viable.
“We put the propellant underground and the signal is recorded on the surface. Like an X-ray, the propellant produces vibrations that aid accuracy before drilling, said Wiwit Suryanto, a researcher at UGM.
Field trials of the technology will be held at the Ciwidey geothermal fields in Java, Indonesia. Wiwit explained that if the trace is successful, the technology could be used worldwide. “If this is successful, search companies will no longer have to drill at multiple locations because they already know which spots are more accurate,” Wiwit added.
Graeme Saunders, CEO of GeoFlow Imaging, expressed hope that UGM could be at the forefront of specializing in the science and technology of exploring geothermal resources. It also welcomed UGM's participation in field testing of the new technology.
Yudistian Yunis, Director of Business Development and Discovery at PT Geo Dipa, expects more from these similar research initiatives. According to Yunis, PT Geo Dipa is open to opportunities for academics to conduct research related to the exploration of geothermal systems.
