Seismic Image and Ava Analyses Using the Reverse Time Migration (rtm) Method with Different Wave Equation Implementations
نویسندگان
چکیده
The purpose of this work is to present and analyze the results of numerical simulations related to the application of three different mathematical models in the acoustic seismic wave propagation in which only compressional waves (P-waves) are contemplated. And present the results of an investigation about how these wave equation implementations can influence the amplitudes of a migrated section in the wave field extrapolation by means of Reverse Time Migration (RTM) approach. The Reverse Time Migration (RTM) method was used in order to derive migrated sections so as to perform a comparison of three different equations: Acoustic Wave Equation and Non-Reflective Wave Equation. The modeling was performed by the Finite Difference Method using a simple model and a complex synthetic Salt model from SEG/EAGE (Society of Exploration Geophysics). From this investigation it is possible to evaluate the quality of migrated seismic images, generating high quality images of complex subsurface geological structures.

An improvement in RTM method to image steep dip petroleum bearing structures and its superiority to other methods
In this paper, first the limitations of the ray-based method and the one-way wave-field extrapolation migration (WEM) in imaging steeply dipping structures are discussed by some examples. Then a new method of the reverse time migration (RTM), used in imaging such complex structures is presented. The proposed method uses a new wave-field extrapolator called the Leapfrog-Rapid Expansion Method (L...
متن کاملPractical issues in reverse time migration: true amplitude gathers, noise removal and harmonic source encoding
Reverse time migration (RTM) is the method of choice for imaging complex subsurface structures. In this paper, we show that slightly modifying the conventional formulation, plus implementing an appropriate imaging condition, yields a true amplitude version of RTM that provides the correct amplitude-versus-angle relation. We also discuss different ways to suppress the migration artifacts and sho...
متن کاملStable attenuation compensation in reverse-time migration
Attenuation in seismic wave propagation is a common cause for poor illumination of subsurface structures. Attempts to compensate for amplitude loss in seismic images by amplifying the wavefield may boost high-frequency components and create undesirable imaging artifacts. In this paper, rather than amplifying the wavefield directly, we develop a stable compensation operator using smooth division...
متن کاملSeismic imaging using internal multiples and overturned waves
Incorporating overturned waves and multiples in seismic imaging is one of the most plausible means by which imaging results might be improved, particularly in regions of complex subsurface structure such as salt bodies. Existing migration methods, such as Reverse Time Migration, are usually designed to image solely with primaries, and so do not make full use of energy propagating along other wa...
متن کاملPreconditioning least-squares RTM in viscoacoustic media by Q-compensated RTM
Reverse-time de-migration (RTDM) is formulated as the adjoint operator of reverse-time migration (RTM). In acoustic medium, RTM provides a good approximation to the inverse of RTDM, and can be used to iteratively invert for the reflectivity image in least-squares RTM (LSRTM). In viscoelastic medium, however, the adjoint of the RTDM operator is far from its inverse because of amplitude attenuati...
