摘要： A first stationary seismic receiver array is provided in a first non-vertically directed first borehole section of a first array of non-vertically directed first borehole sections, and a second stationary seismic receiver array is provided in a second non-vertically directed first borehole section of the first array of non-vertically directed first borehole sections. A seismic source assembly is moved axially through a first non-vertically directed second borehole section from at least a first position to a second position of a plurality of first borehole positions along a length of the first non-vertically directed second borehole section. The seismic source assembly contains a repeatable seismic source, which is activated when the seismic source assembly is in the first position and when the seismic source assembly is in the second position. First and second shots of seismic signals are recorded with at least each of the first and second stationary seismic receivers.

摘要： Receiver-consistent scalars of seismic receiver channels are used for time-lapse monitoring of a sub-surface earth formation. Signals are induced by seismic waves propagating through the earth formation adjacent to each respective seismic receiver channel. Each seismic receiver channel is acoustically coupled to the earth formation as present directly adjacent to the location of the seismic receiver channel in question. The base receiver-consistent scalars and the monitor receiver-consistent scalars of seismic receiver channels can be outputted to reveal changes in these receiver-consistent scalars. These changes can be used to delineate information about physical changes in the subsurface earth formation. The changes in the based receiver-consistent scalars and the monitor receiver-consistent scalars may be displayed visually.

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： A method may include providing a sensor in a first wellbore segment, providing a sensor in a second wellbore segment, observing upgoing acoustic waves or downgoing acoustic waves with the sensors, and separating the upgoing acoustic waves and/or the downgoing acoustic waves from a total wavefield. The first wellbore segment and the second wellbore segment may be separated by a distance. At least one of the wellbore segments may be non-vertical and/or the first wellbore segment may not be parallel to the second wellbore segment. The first wellbore segment may be part of a first set of wellbores and the second wellbore segment may be part of a second set of wellbores. The separated upgoing and downgoing acoustic waves may be used to generate deghosted data.
