... of a few megabytes in memory, which enables it to operate in real-time. During monitoring, FMNet only takes about 200 ms to complete analysis once the data has been received. The neural network we designed can be described as a fully convolutional network (FCN). FCNs are supervised deep learning networks...

... various alteration processes and possible feedback upon each other impact fluid flow within the stimulated rock volume. In this study, we conducted a time-lapse acoustic monitoring of fracture propping and acidizing on clay-rich (carbonate-poor) Marcellus shales. We simulated fracture propping by filling...

... Abstract This contribution demonstrates the potential to use muon tomography for monitoring Steam Assisted Gravity Drainage hydrocarbon reservoirs. To do this, density changes are modeled at two times after initial production, namely 1.5 and 5 years. Simulated muon detector arrays are used...

... Abstract Fiber-optic distributed acoustic sensing (DAS) offers advantages in time-lapse VSP seismic monitoring of an unconventional reservoir. Petrophysical changes to the reservoir due to hydraulic fracturing of the rocks change the character of seismic waves. Repeatable DAS VSP measurements...

... Abstract Hydraulic fracturing operations in unconventional reservoirs are typically monitored using geophones located either at the surface or in adjacent wellbores. A new approach to record hydraulic stimulations utilizes fiber-optic Distributed Acoustic Sensing (DAS). A fiber-optic cable...

... Summary In 2010 a noise test and microseismic emission detection test was performed in the Horn River Basin in northeastern British Columbia, Canada, to determine the suitability for surface microseismic monitoring and the character of the near-surface noise in an effort to determine...

..., distribution, or storage of any part of this paper without the written consent of URTeC is prohibited. Abstract The ability to minimize lost and/or unaccounted production of well pad facilities can benefit from an overall systems approach to the monitoring, control and optimization of critical operations...

... Summary Downhole seismic monitoring of an unconventional tight-sand unit in central Alberta was undertaken during a multi-stage hydraulic fracture (HF) treatment in September 2012. Acquisition of continuous passive seismic data continued during the subsequent flowback and production periods...

... Summary We describe the results of monitoring several hydraulic fracture treatments in the Marcellus formation using two microseismic monitoring arrays: one deep twelve-3C-geophone array located in a vertical wellbore and a series of multi-component seismic sensors installed in a grid of 140...

We report a new application: imaging ambient seismic activity both prior to frac monitoring and by quiet-time monitoring using 3D reflection grids, i.e. by recording on a reflection grid or dedicated passive seismic grid when shooting or vibrating is not in progress. The resulting images reveal...
