Focal Mechanism Determination of Induced Microearthquakes in an Oil Field Using Full Waveforms from Shallow and Deep Seismic Networks
Li, Junlun; Kuleli, Huseyin Sadi; Zhang, Haijiang; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2011-05-09)A new, high frequency, full waveform matching method is used to study the focal mechanisms of small, local earthquakes induced in an oil field, which are monitored by a sparse near-surface network and a deep borehole ... -
Focal Mechanism Determination Using High Frequency Waveform Matching and Its Application to Small Magnitude Induced Earthquakes
Li, Junlun; Zhang, Haijiang; Kuleli, Huseyin Sadi; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)We present a new method using high frequency full waveform information to determine the focal mechanisms of small, local earthquakes monitored by a sparse surface network. During the waveform inversion, we maximize both ... -
Focal Mechanism Determination using High Frequency, Full Waveform Information
Li, Junlun; Zhang, Haijiang; Kuleli, Huseyin Sadi; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2009)In this research, we use high frequency waveform information to determine the focal mechanisms of small local earthquakes at an oil reservoir. During the waveform inversion, we maximize both the phase and amplitude matching ... -
Full-waveform Based Microseismic Event Detection and Signal Enhancement: The Subspace Approach
Song, Fuxian; Warpinski, Norm R.; Toksoz, M. Nafi; Kuleli, Huseyin Sadi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)Microseismic monitoring has proven to be an invaluable tool for optimizing hydraulic fracturing stimulations and monitoring reservoir changes. The signal to noise ratio (SNR) of the recorded microseismic data varies ... -
An improved method for hydrofracture induced microseismic event detection and phase picking
Song, Fuxian; Kuleli, Huseyin Sadi; Toksoz, M. Nafi; Ay, Erkan; Zhang, Haijiang (Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)The ability to detect small microearthquakes and identify their P and S phase arrivals is a key issue in hydrofracture downhole monitoring because of the low signal-to-noise ratios. We apply an array-based waveform ... -

Cornish, Bruce; Quirein, John; Ay, Erkan; Pei, Donghong; Zannoni, Steve; e.a. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2009)The ability to detect small microseismic events and identify their P and S phase arrivals is a key issue in hydraulic fracture monitoring because of the low signal-to-noise ratios. We propose a array-based waveform ... -
Passive Seismic Tomography Using Induced Seismicity at a Petroleum Field in Oman
Kindy, Fahad; Zhang, Haijiang; Sarkar, Sudipta; Toksoz, M. Nafi; Kuleli, Huseyin Sadi; e.a. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2009-05-19)A borehole network consisting of 5 monitoring wells was used to monitor the induced seismicity at a producing petroleum field for a period of about 11 months. Nearly 5400 microseismic events were analyzed and utilized ...
