A seismic data acquisition device and a seismic data acquisition method are disclosed. The seismic data acquisition device includes an anti-aliasing filter, a first conversion circuit, a second conversion circuit, and a controller. The anti-aliasing filter has an input configured to receive seismic data, which is generally an analog signal. The anti-aliasing filter has an output connected to an input of the first conversion circuit and an input of the second conversion circuit, respectively. The first conversion circuit has an output connected to a first input of the controller. The second conversion circuit has an output connected to a second input of the controller. The seismic data acquisition device and method enable wide dynamic seismic data acquisition with high resolution over the full amplitude range of the (seismic data) input signal.

The techniques and device provided herein relate to receiving, via a processor, image data representative of a borehole of a well. The technique may include generating dequantized image data based on the image data, such that the dequantized image data filters one or more artifacts present in a Hough transformed version of the image data. One or more dip orientations (inclination and azimuth) associated with one or more formation dips present in the image data may be determined based on the dequantized image data. The technique may also include performing an a-contration validation algorithm for for the one or more formation dips to verify whether at least a formation dip having the or one of the possible dip orientation is present at a predetermined measured depth in the image data.
