COMPENSATION OF NON-SYNCHRONICITY OF RECORDS FOR DOWNHOLE MICROSEISMIC MONITORING SYSTEMS IN CASE OF VTI MEDIA ANIZOTROPY

Interexpo GEO-Siberia, 2019
Downhole microseismic monitoring sometimes includes the installation of several downhole surveillance systems. One of the key hardware requirements is accurate synchronization of the records received. Usually this problem is solved at the hardware level, and in the case of ideal observations, additional correction procedures are not required.

Precise Temperature Measurements and Long‐Term Observations Revealed an Almost‐Constant Temperature Zone in a Vertical 700‐m‐Deep Borehole in the Aso Volcanic Region

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract To determine the subsurface temperature distribution and its relevance to groundwater flow in the deep subsurface, we repeated temperature depth profile measurements and conducted long‐term temperature observations in an ∼700‐m‐deep borehole penetrating the Futagawa fault along the Kiyama–Kashima graben in the Aso volcanic region, Japan from ...

Temperature Compensation Method Based on Bilinear Interpolation for Downhole High-Temperature Pressure Sensors

Sensors
Due to their high accuracy, excellent stability, minor size, and low cost, silicon piezoresistive pressure sensors are used to monitor downhole pressure under high-temperature, high-pressure conditions. However, due to silicon’s temperature sensitivity, high and very varied downhole temperatures cause a significant bias in pressure measurement by the ...
