Abstract: A system has a tool capable of obtaining data that characterizes a stimulated reservoir or from which the stimulated reservoir can be characterized. The system also includes a processor capable of predicting the production of the stimulated reservoir using the characterizing data and outputting the predicted production. A reservoir may be stimulated using a stimulation process and data may be obtained that characterizes the stimulated reservoir or from which the stimulated reservoir can be characterized. The production of the stimulated reservoir may be predicted using the data. Alternatively, a reservoir may be stimulated using a stimulation process and data that characterizes the stimulated reservoir or from which the stimulated reservoir can be characterized may be obtained. One or more 3-D volumes may be produced based on the characterizing data, and inferences about the stimulated reservoir may be made using the one or more 3-D volumes.

Abstract: Methods and systems are described for measuring effects of a hydraulic fracturing process. The techniques can utilizes cross-well seismic technology, such as used in Schlumberger's DeepLook-CS tools and service, or in some case surface to borehole or borehole to surface seismic technology. The downhole seismic sources at known locations can be conventional sources or can be other types of equipment operating at known locations such as perforation guns. The source is activated or swept creating energy which is transmitted through the formation. The energy is recorded at the receiver array and processed to yield a tomographic image indicating changes in the subterranean formation resulting from the hydraulic fracturing process. The process can be performed pre and post hydraulic fracture stimulation to generate a difference image of propped fractures in the reservoir.

Abstract: A computer-implemented method of accounting for angle-dependent wavelet stretch in seismic data based on a novel relationship between wavelet stretch and the cosine of a reflection angle of an acoustic ray. Conventional seismic data having at least one wavelet, such as data generated from a reflection seismic survey, is accessed. The data is processed such that at least one wavelet is subject to angle-dependent wavelet stretch. A reflection angle for at least one wavelet is also determined. An operator is utilized to calculate a wavelet stretch factor for at least one wavelet based on the cosine of the corresponding reflection angle of the wavelet. The wavelet stretch factor is applied to the seismic data to account for angle-dependent wavelet stretch.
