Detection for Anomaly Data in Microseismic Survey
2009 Third International Symposium on Intelligent Information Technology Application, 2009With the development and application of modern science and technology, many new technical measurement methods have been put forward successively which are of high resolution and high collection rate about microseismic monitoring. We urgently need an effective detection method of abnormal data (mine earthquake) to collect lots of data to make real-time ...

Geomechanical Reservoir Characterization with Microseismic Data
SPE Eastern Regional Meeting, 2013Abstract Bulk fluid injection into low permeability geologic formations been observed to trigger microearthquakes (MEQs). Triggering of MEQ events has been linked to pore pressure, temperature, and in-situ stress variations. The resulting clouds of micro-seismic events are believed to carry information about the underlying coupled flow ...

Collection of microseismic intensity data: a model for Turkey
Arabian Journal of Geosciences, 2021Among alternative descriptors of seismic effects, intensity is a significant measure. Along with the instrumental ground motion parameters, seismic intensity has been recently used extensively. Despite the subjectivity involved in their estimation, intensity values provide valuable information regarding the distribution of seismic effects. Correlations

Data-acquisition design for microseismic monitoring
The Leading Edge, 2010Microseismic monitoring of hydraulic well treatments is one of the most useful seismic techniques that can aid the development of tight-gas and shale-gas fields. The main challenge in these fields is an extremely low formation permeability, which lies in the microdarcy or even nanodarcy range and requires thousands of closely spaced wells to drain the ...

SNR Enhancement for Downhole Microseismic Data Using CSST
IEEE Geoscience and Remote Sensing Letters, 2016Noise contamination is a significant issue in microseismic data processing due to the low magnitude of high-frequency downhole microseismic signals induced during fluid injection. In this letter, a noncoherent noise attenuation technique based on cycle spinning shearlet transform (CSST) is presented. The CSST algorithm is implemented in three steps. In

Completions and reservoir engineering applications of microseismic data
SEG Technical Program Expanded Abstracts 2014, 2014Evaluating hydraulic fracturing treatments by employing passive seismic monitoring technology has become an accepted industry practice and standard in the last decade foremost for unconventional resources. Due to microseismic monitoring it is now understood that the fracture created during hydraulic stimulation greatly deviates from the planar bi-wing ...

Survey Design and Microseismic Data Acquisition
2020This chapter explains the common objectives and planning aspects of a microseismic survey. We will see how the information gathered from the available and already completed projects can be useful in the pre-survey design modeling. Moreover, we will discuss the role of full-waveform modeling and ray tracing tools in the evaluation of event detectability

Microseismic data from Aquistore (Canada).
2016This data set includes microseismic and structural geological data collected at Aquistore (Canada). They cover a period from 26th April - 21st June 2015, during which CO2 was being injected in the Aquistore injection well at 3.5 km depth. The data were collected in the framework of a research project funded by UKCCSRC (EPSRC) and based at Aquistore in ...

4D Tomography and Deformation from Microseismic Data
International Meeting for Applied Geoscience & Energy, 2015Summary Microseismic data is used to calculate seismic deformation in response to hydraulic fracturing throughout a reservoir. This information is incorporated into a 4D tomography code that calculates temporal changes in seismic velocity over the volume of the reservoir as deformation occurs.
