The acquisition footprint noise in migrated sections consists of migration artifacts associated with a discrete recording geometry. Such noise can corrupt the interpretation of seismic sections, especially for AVO studies, so it is critical to design an optimal seismic survey that generates the smallest footprint. Our previous work showed that the Seismic Array Theorem can be used to design bet...

In this paper it is presented a volcanic seismic acquisition equipment that has been developed together with an energy harvesting system, based on piezoelectric elements, in order to work in autonomous conditions. The energy harvesting system has been developed to convert the wind or marine currents energy into electrical energy through a new method based on piezoelectrics. For the deployment o...

Reservoir modeling is the process of generating numerical representations of reservoir conditions and properties on the basis of geological, geophysical, and engineering data measured on the Earth’s surface or in depth at a limited number of borehole locations. Therefore, reservoir modeling requires an incorporation of the data from a variety of sources, along with an integration of knowledge a...

Compressed sensing (CS) or compressive sampling provides a new sampling theory to reduce data acquisition, which says that compressible signals can be exactly reconstructed from highly incomplete sets of measurements. Very recently, the CS has been applied for seismic exploration and started to compact the traditional data acquisition. In this paper, we present an optimized sampling strategy fo...

Seismic acquisition and monitoring system can collect, store, analyze and dispose the rock burst seismic waves or the vibration of other objects. This paper utilizes single chip computer technology, virtual instrument technology, sensor technology, database management technology, wavelet analysis technology, combining the real condition of the mine microseismic signal to establish a set of mine...

The fidelity of full vector seismic data acquired with systems of three-component (3C) receivers that are rigidly attached to an acquisition device is evaluated. The acquisition device is designed for rapid and cost-effective imaging of the upper 30m of the earth's surface. Multi-mode analysis of full vector seismic data has the potential to provide engineers and geophysicists with near-surface...

In the article ‘Illuminating Resolution’ (GEO ExPro Vol. 8, No. 3) we described the evolution of seismic acquisition technologies that aim to achieve the geophysicists’ goals of illumination and resolution. One development featured in the article is the concept of extending the frequency content or bandwidth of seismic signals, especially at the low-frequency end, in order to achieve better ver...

In this talk I will introduce marine seismic acquisition technologies and focus on solutions to maximize the bandwidth of the measured data. This involves detecting and removing the components of the wavefields that are reflected at the sea surface and that propagate downward: these downgoing reflections, called “ghosts” in literature, interfere with the upgoing wavefield, that is generated by ...

Acquisition design plays a very significant role in seismic exploration and data processing. An optimized seismic acquisition design will require less resources and therefore, it can reduce the total cost of seismic exploration. Nevertheless, finding the optimal locations of sources and receivers in a seismic survey is a long-standing problem which has received less attraction in last few decad...
