DETERMINING LOCATION INFORMATION OF MICROSEISMIC EVENTS DURING HYDRAULIC FRACTURING |
摘要 |
A method of determining locations of microseismic events caused by a hydrofracking process is disclosed. The method includes: measuring audio signals using an array of geophones deployed in a monitoring well during hydraulic fracturing; modifying the audio signals according to a predefined nonlinear distortion operator to generate a modified audio signal, wherein the modified audio signal has audible components in a predefined frequency range beyond a cutoff frequency defined by a sampling rate of the respective measured audio signals; and playing the modified audio signals through a stereo or multi-channel speaker system, wherein a user of the stereo or multi-channel speaker system is able to determine the locations of the microseismic events from listening to the modified audio signals. |
