(1) CCUS / EOR monitoring by ground-to-ground configration

(2) CCUS / EOR monitoring by cross hole configration

We have succeeded in cooling and operating the superconducting magnetic sensor in a container that is capable of electromagnetic exploration up to 10 KHz, has a water pressure resistance of 70 MPa (water depth 7000 m), and is heat resistant to 200 ℃ with JOGMEC (Japan Oil, Gas and Metals National Corporation) and MINDECO (MITSUI MINERAL DEVELOPMENT ENGINEERING CO., LTD). It was put into a test well at a depth of about 300 m, and it was confirmed that the transmitted waveform of the magnetic field could be received inside the steel pipe.
