Cymric oil field frequency domain electromagnetic (FEM) data with two parts of data labeled Part 1 and Part 2. Part 1 utilizes an electrical source line parallel to the receiver line, while Part 2 utilizes an electrical source line at a 75 deg angle to the receiver line. Data are plotted and compared to numerically modeled data to observe electric field response to well structure. In two configuration files are diagrams of the experiment layout.
Survey layout for Part 2, shown as an aerial image with the source and receiver lines labeled with respect to well 2-8.

This experiment is testing the tube waves reflected from the bottom of the well. We put six single-channel geophones on the surface and a 24-channel downhole hydrophone into the well. The well is about 30 meters deep. Just a steel casing in the sand formation, no cement. The figure of processed upgoing VSP data of 1.sgy

The coaxial-cable experiment conducted in the lab was with 80 m coaxial cable( RG-85). This experiment compares the TDR response between damaged and undamaged cable. For the damaged cable, the damaged section is in the middle (40 m). The amplitude of the data is mV.
TDR response of the undamaged coaxial cable with shorted termination. The amplitude of the data is mV.

This test was conducted at the Chevron Cymric oilfield in the California central valley near Bakersfield. A reflected seismic signal was observed in all three components (x, y, z) of the 3-component Episensor geophone, as well as all phones on the single component array. The arrival time of the reflected seismic signal matches calculations based on a reasonable velocity model (~650 m/s). The seismic data has three channels that are from the 3-C Broadband Episensor, then from 4th -- 12th channels has no data. Channel 13 -- 25 are surface single change vertical geophones. The source of this seismic survey is weight drop. More info could be found from the data header and the attached PPT file. This is the geometry setup and the resulted figures from this survey.
