Magnetotelluric sounding data

Measurements with MRS and SBNMR in Benin, 2015

Time-lapse MRS measurements in Villamblain (France), 1999-200

Parameters of the electrical source in all models were set the same as below: the moment of the source was set to 40000A.m, it was oriented along x-direction with its midpoint at x=0m, y=0m.

"L1150-raw data" is the raw field data for line L1150 which is collected from a coal mine in Shandong, China. "L1150-preprocessed by de-noising and filtering.txt" is the field data preprocessed by de-noising and filtering for inverting.

Data_10512 is generated using Loki, which is a 3D forward modeling program (Raiche et al., 2007). Sferics is from a field survey. the three *.raw files are borehole TEM data recorded by SmarTem24.

The research data include the program for solving gravity and magnetic anomalies of parallel pipeline, the program for calculating the demagnetization coefficient of a pipeline, the standard for determining the range of parallel pipeline parameters, the program for the effect of parallel pipeline parameters on the characteristics of gravity and magnetic surveys, the magnetic anomaly acquisition equipment and parallel pipeline magnetic anomaly observed data.

Measurements of porosity, aspect ratio, Vp and Vs for a pressure range of 2.5-40.5 MPa (hydrostatic) in Dry carbonate rocks. Ultrasonic frequencies 1.3 MHz (P-wave) and 900 KHz (S-wave). Lead Foil was used as couplant.
