摘要: Since the dawn of logging-while-drilling (LWD) in 1980s, industry has wanted a reliable while-drilling borehole seismic measurement. However, number technical roadblocks prohibited its realization until recently. These difficulties included nature and required accuracy measurement, timing issues, sensors, automation, lack an electrical connection between downhole tools surface configuration.
