... attributes are applied to predict multiscale faults and karst caves, large scale faults (>1/4λ) are identified based on seismic discontinuity, while medium scale faults (>1/100λ and <1/4λ) are detected using maximum curvature attribute. Principal Component Analysis (PCA) and unsupervised clustering...

... Based on the first-order derivative, gradient estimation and curvature estimation based on the second-order derivative are important tools for imaging geological discontinuities such as faults and stratigraphic features. The curvature attributes based on 3D surface seismic data are usually...

..., most-positive of principal curvature, most-negative principal of curvature, dip deviation, and aberrancy were the best candidates. Then, the detected faults were overlayed independently on top of ant tracking and fault enhancement attribute products, as well as microseismicity data. Initial results...

... Unconventional reservoirs typically feature thin box and develop low-relief structures, which make horizontal well drilling susceptible to top-bottom outbursts, leading to the loss of horizontal segments. The commonly used curvature attribute value is usually the extreme value of a certain point...

... Conventional methods for computing volumetric curvatures of subsurface geological features are based on the lateral derivatives of pre-computed inline/crossline dips of assumed local 2D surfaces in 3D space. We suggest a more universal approach, considering the subsurface structural features...

... Reflector-normal vectors and reflector-curvature parameters are the principal geometrical attributes used in seismic interpretation for characterizing the orientations and the shapes of geological reflecting surfaces. The input dataset for their computation consists of fine 3D grids of scalar...
