Reverse-time migrationWe developed a reverse-time migration scheme that can image regions with rugged topography without requiring any approximations by adopting an irregular, unstructured-grid modelling scheme. This grid, which can accurately describe surface topography and interfaces between high-velocity-...

Reverse Time Migration (RTM) has become the method of choice for seismic imaging in complicated areas. The method is based on directly solving the wave equation in the time domain (as opposed to the frequency domain). RTM can accurately handle any variation in subsurface material properties, ...
Reverse time migration is an ultrahigh-end prestack two-way wave-equation migration for accurate imaging in and below areas with both great structural and velocity complexities, such as sedimentary areas with steep salt inclusions. RTM has a proven track record for generating final ...
Educational_reverse-time-migration是一个教育级别的二维声波逆时偏移(RTM)代码。它旨在为学习者提供一个简单而有效的工具,用于理解和实践声波逆时偏移技术。该代码包含了基本的RTM算法,通过追踪地下介质中声波传播的路径,并根据接收到的地震数据反演地下介质的模型。它适用于学生、研究人员和初学者,可用于学习声波逆时...
Migration of stacked or zero-offset sections is based on deriving the wave amplitude in space from wave field observations at the surface. Conventionally this calculation has been carried out through a depth extrapolation. We examine the alternative of carrying out the migration through a reverse ti...
Reverse time migration case_1 今天分享下the simplest case of rtm。 逆时偏移的实现跟把“大象装冰箱”的步骤十分相似,总共分成简单的三步: 1.从源开始的正向波传播 2.将接收位置处的接收信号时间翻转过来,当做源,在相同的模型下反传回去 3.应用成像条件,确定层界面的位置...
This paper presents a reverse-time migration algorithm as the conjugate of the forward time-extrapolation modeling. The conjugate operator is obtained by formulating the forward operator explicitly and by transposing the forward operator. The algorithm is tested by a numerical experiment for a 1-D ...
3.1. Reverse-time MigrationBefore describing the methodology and performance of reverse-time migration, it should be stated that it is only one of about four accurate depth migration methods. As described by Whitmore et al. (1988), these four methods include phase-shift plus interpolation migration...
