Migration with arbitrarily wide-angle wave equations
We develop a new scalar migration technique that is highly accurate for imaging steep dips in heterogeneous media. This method is based on arbitrarily wideangle wave equations (AWWEs) that are highly accurate space-domain one-way wave equations and have a form similar to the 15◦ equation. The accuracy of the proposed method is increased by introducing auxiliary variables, as well as adjusting t...
متن کاملElastic Prestack , Reverse - Time Migration
Elastic prestack, reverse-time depth migration is applied to both synthetic data and four-component eld data from the Valhall area. Reverse-time extrapolation of the recorded multi-component data is by 2-D elastic nite di erence solution to the full wave equation. An eikonal solver is used to compute the acoustic traveltime from the source to the image points. By using horizontal inline and ver...
متن کاملArbitrarily wide-angle wave equations for complex media
By combining various ideas related to one-way wave equations (OWWEs), half-space stiffness relation, special finiteelement discretization, and complex coordinate stretching, a systematic procedure is developed for deriving a series of highly accurate space-domain versions of OWWEs. The resulting procedure is applicable to complex media where the governing equation (full wave equation) is a seco...
متن کاملPrestack imaging of overturned reflections by reverse time migration
We present a simple method for computing angle-domain Common Image Gathers (CIGs) using prestack reverse time migration. The proposed method is an extension of the method proposed by Rickett and Sava (2001) to compute CIGs by downward-continuation shot-profile migration. We demonstrate with a synthetic example the use of the CIG gathers for migration velocity updating. A challenge for imaging b...
متن کاملWide-azimuth angle-domain imaging for anisotropic reverse-time migration
Extended common-image-point gathers (CIP) constructed by wide-azimuth TI wave-equation migration contain all the necessary information for angle decomposition as a function of the reflection and azimuth angles at selected locations in the subsurface. The reflection and azimuth angles are derived from the extended images using analytic relations between the space-lag and time-lag extensions. Thi...
