摘要： A method for characterizing a subsurface fluid reservoir includes inducing a pressure wave in a first well traversing the subsurface reservoir. A pressure wave in at least a second well traversing the subsurface reservoir is detected. The detected pressure wave results from conversion of a tube wave generated by the pressure wave in the first well into guided waves. The pressure wave in the at least a second well is generated by conversion of the guided waves arriving at the at least a second well. A guided (K) wave travel time from the first well to the at least a second well is determined and a physical property of the subsurface fluid reservoir is determined from the K-wave travel time.

摘要： Downhole seismic receiver systems that may be compatible with measurement-while-drilling systems. The downhole seismic receiver systems may be integrated into drill-string components, including drill collars of a bottom hole assembly. The downhole seismic receiver systems include one or more receiver subsystems which in turn include at least two or more same-type seismic sensors. The downhole seismic receiver systems are compatible with low frequency seismic sources and may be useful in determining orientation and location of bed boundaries around a wellbore and ahead of a drill-bit. The downhole seismic receiver systems can be operated with a downhole or surface source. Methods for downhole seismic, including single well and cross-well seismic. The methods may include analyzing data acquired by the receiver systems to obtain seismic information around the wellbore and ahead of the drill bit.

摘要： A seismic source (50) is buried in a multi-layered subsurface formation below a fast layer (30) and above a reflecting interface (10). The seismic source (50) excites a critically refracted (CR) wave that travels laterally along a fast layer bottom interface (35), and emanates downwardly into a slow layer (40) that is below and adjacent to the fast layer (30). One or more receivers (60), positioned below the fast layer (30) and above the reflecting interface (10) are used to detect seismic waves (84, 86). The one or more receivers (60) are positioned within a borehole (65). At least one reflected CR wave is isolated from the received signals, which is a CR wave that has reflected off of the reflecting layer (10) below the one or more receivers (60). A seismic profile of the multi-layered subsurface formation is created, using the at least one reflected CR wave. Time-lapse seismic monitoring of hydrocarbon extraction operations, such as steam injection, is also provided.

摘要： Some aspects of what is described here relate to seismic profiling techniques. A seismic excitation is generated at a seismic source location in a directional section of a fracture treatment injection wellbore in a subterranean region. A seismic response associated with the seismic excitation is detected at a seismic sensor location in the directional section of the fracture treatment injection wellbore. The seismic response includes a reflection from the subterranean region. A fracture treatment applied through the fracture treatment injection wellbore is analyzed based on the reflection.

摘要： Microseismic-event data can be corrected (e.g., to reduce or eliminate bias). For example, a first distribution of microseismic events that occurred in a first area of a subterranean formation can be determined. The first distribution can be used as a reference distribution. A second distribution of microseismic events that occurred in a second area of the subterranean formation can also be determined. The second area of the subterranean formation can be farther from an observation well than the first area. The second distribution can be corrected by including, in the second distribution, microseismic events that have characteristics tailored for reducing a difference between the second distribution and the first distribution.

摘要： Methods are provided for tracking carbon dioxide (CO2) migration in a hydrocarbon-bearing reservoir located under a cap rock in a formation. In one embodiment, at least one seismic source and a plurality of receivers are located in spaced boreholes in the formation with the sources and receivers located near or at the reservoir so that direct paths from the sources to the receivers extend through the reservoir. CO2 is injected from the borehole containing the seismic sources into the reservoir, and the sources are activated multiple times over days and seismic signals are detected at the receivers. From the detected signals, time-lapse travel delay of direct arrivals of the signals are found and are used to track CO2 in the reservoir as a function of time. In another embodiment, the sources and receivers are located above the reservoir, and reflected waves are utilized to track the CO2.

摘要： A method for correcting a fracture model of a reservoir includes receiving a seismic signal from seismic events due to a plurality of stimulated reservoir stages to provide detected seismic event information and estimating a number of undetected seismic events and a magnitude for each of the undetected seismic events to provide undetected seismic event information for each stage. The detected seismic event information and the undetected seismic event information provide corrected seismic event information for each stage. The method further includes calculating a scaling factor for each stage using a scalar property of the corresponding stage and a reference stage scalar property, applying the scaling factor for each stage to the corrected seismic event information to provide scaled seismic event information for each stage, and correcting the fracture model with the scaled seismic event information for each stage to provide a corrected fracture model.
