WISE-CASING: Surface Seismic Survey at Cymric Field, California Central Valley

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.

本次试验于加利福尼亚州中谷地区的贝克菲尔德附近雪弗龙Cymric油田进行。在3分量Episensor地震检波器的x、y、z三个分量以及单分量阵列的所有电话上均观测到了反射地震信号。反射地震信号的到达时间与基于合理速度模型（约650米/秒）的计算相吻合。该地震数据包含三个通道，来自3-C宽带Episensor，随后从第4至第12通道缺失数据。第13至第25通道为地表单分量垂直地震检波器。本次地震调查的震源为重量坠落。更多详细信息可从数据头文件及所附PPT文件中获取。
