摘要: The present disclosure includes a method for monitoring a subsurface formation including disposing an antenna in a horizontal wellbore, the antenna including a plurality of piezoelectric modules. A voltage signal is applied to at least one of the piezoelectric modules to cause the at least one piezoelectric modules to emit seismic energy into the subsurface formation. A resulting signal is received at a receiver. A property of the subsurface formation is determined based, at least in part, on the resulting signal.

摘要: The present disclosure includes a method for stabilizing controlled seismic signals based on uncontrolled seismic signals. The method includes calculating reconstructed signals associated with a first receiver. Each reconstructed signal is based on uncontrolled signals recorded by a respective pair of receivers that includes the first receiver and a respective second receiver. The method also includes calculating signal variations. Each signal variation is associated with a respective pair of receivers and based on a difference between the reconstructed signal associated with the respective pair of receivers and a reference associated with the respective pair of receivers. The method also includes calculating a stabilization factor for the first receiver based on the first signal variations. The method also includes modifying controlled seismic signals recorded by the first receiver by applying the stabilization factor to the controlled seismic signals. The present disclosure may also include associated systems and apparatuses.

摘要: Systems and methods for wireless data acquisition in seismic monitoring systems are disclosed. The method includes obtaining a signal table for an emitted seismic signal, receiving seismic signal data from a receiver configured to transform seismic signals into seismic signal data, and storing the seismic signal data on a storage system. The method also includes determining a time span for the seismic signal data and generating a reduced data set based on the seismic signal data, the signal table, and the time span.

摘要: A method for acquiring and improving seismic data includes activating a first seismic source located below a geophysical surface at a first depth and a second seismic source located below the geophysical surface at a second depth, wherein the second depth is below the first depth, acquiring seismic data with a seismic receiver in conjunction with activating the first seismic source and the second seismic source, and aligning primary reflections within the seismic data to provide improved seismic data. The method may also include determining changes to the regions below the second depth by comparing improved seismic data corresponding to a first acquisition event with improved seismic data corresponding to a second acquisition event. A corresponding system is also disclosed herein.

摘要: A system and method for performing seismic exploration with multiple acquisition systems is disclosed. The method includes configuring a first seismic source located outside of an exclusion zone and configuring a second seismic source located inside of the exclusion zone. The method further includes obtaining a first seismic dataset corresponding to a first seismic signal emitted by the first seismic source and obtaining a second seismic dataset corresponding to a second seismic signal emitted by the second seismic source. The method further includes combining the first and second datasets to create a complete dataset covering a survey area and creating a seismic image of a subsurface of the survey area.
