英文摘要	LBNL's recent analysis of the microseismic data being acquired at well KB-601 has produced a new result of significantly more microseismic activity than previously estimated. During 2009-2010, there was background activity of 1 or 2 events per day with a notable increase during the spring-summer months of up to 20 or more events in a signal day (Figure 1). This level of activity warrants increased effort to obtain quantitative information, and supports plans for expansion of the microseismic monitoring. Quantitative interpretation of these events, including locations, is still hampered by physically unrealistic data from some sensors and uncertainty in which sensors are being recorded and their depth. We now believe that some quantitative analysis will be possible, building upon LBNL's earlier work and analysis conducted by Pinnacle, and utilizing the sledge-hammer tests conducted in the fall of 2010 by the JIP. Current acquisition problems include electrical noise, lack of GPS clock timing, and the sensor uncertainty. To address the acquisition problems, we continue to recommend an active-source recording test with full 144 channel capability (or at least 48 channel). We also recommend a site visit for debugging and repair by a technician knowledgeable in the REF TEK recording system and microseismic acquisition.
