The essential oil (EO) obtained from the leaves and flowers of Hyptis suaveolens (L.) Poit. collected from Guasdualito, Apure State, Venezuela. Oil was obtained by hydrodistillation using a Clevenger trap. The oil was analyzed by gases chromatography

ABSTRACT Amplitude preservation in Pre-Stack Depth Migration (PSDM) processes that use wave field extrapolation must be ensured - first, in the operators used to continue the wavefield in time or depth, and second, in the imaging condition used to es

Building accurate velocity models is of major interest for oil and gas companies because it improves the prospect evaluation and reduces the risk of geohazards. Full-waveform inversion (FWI) has become a popular method for finding high-resolution and

Reverse-Time Migration (RTM) is a two-way wave-equation based method used to generate images of the Earth's subsurface. RTM has been successfully used in seismic imaging as it allows defining complex structural areas. However, RTM is a highly computa

An implementation of the Orthogonal Matching Pursuit (OMP) algorithm was used and the results obtained therefrom are presented for simultaneous interpolation and denoising from seismic signals in the framework of sparse signal representation. OMP is

One-way wave equation migration is a powerful imaging tool for locating accurately reflectors in complex geologic structures; however, the classical formulation of one-way wave equations does not provide accurate amplitudes for the reflectors. When d
