Abstract
This joint study with Sandia National Lab developed a new chemical-based sensor to map flowing fractures in geothermal reservoirs and estimate their flow rates in real-time. A previous downhole tool design was adapted to withstand temperatures up to 225°C. The project had two phases, laboratory testing and field deployment. The tool was modified and tested in the laboratory under simulated field conditions, using experiments and numerical modeling. The tool was then deployed successfully in two geothermal wells at the Utah FORGE site. The tool demonstrated its effectiveness in identifying individual fractures and quantifying the flow of water from them
The presentation will discuss the BS, MS and PhD research work of Nilufer Atalay, Xuhua Gao, Luthfan Judawisastra, Marshall Hartung, Sarah Sausan, Petch Ounjaroen and Ben Anantachaisophon.
