摘要： Application task management ("ATM") methods may employ a task list stored in a file on a nonvolatile information storage medium. Parallel processing instances employ an application programming interface ("API") that enables each processing instance to individually access the task list. The access protocol enforced by the API is sufficient to provide robust, fault-tolerant behavior without requiring a specific process or daemon to be responsible for ATM. The API may employ a locking mechanism based on universal or widely-available operating system calls (such as directory creation) that implicitly or explicitly guarantee atomic operations. Each processing instance performs a check-out of unfinished tasks with a request that includes a timeout value, transforms the unfinished tasks into finished tasks, and provides a check-in of the finished tasks, and repeats. This approach supports the use of a variety of models through the use of chained or nested task lists, and it can be readily scaled.
摘要翻译：应用程序任务管理（“ATM”）方法可以使用存储在非易失性信息存储介质上的文件中的任务列表。并行处理实例使用应用程序编程接口（“API”），使每个处理实例能够单独访问任务列表。 API实施的访问协议足以提供强大的容错行为，而不需要特定的进程或守护进程负责ATM。 API可以采用基于通用或广泛可用的操作系统调用（例如目录创建）的锁定机制，这些调用隐含或明确地保证原子操作。每个处理实例使用包含超时值的请求执行未完成任务的检出，将未完成的任务转换为已完成的任务，并提供已完成任务的签入并重复执行。这种方法支持通过使用链接或嵌套任务列表来使用各种模型，并且可以轻松地缩放。

摘要： A method is described for seismic imaging improved by an estimation of attenuation including receiving a pre-migration seismic dataset D(s,r;t) representative of a subsurface volume of interest wherein s indicates source location, r indicates receiver location, and t is the recorded travel time; calculating a pre-migration attenuated travel time t*(s,r;t); computing a time derivative of the pre-migration attenuated travel time wherein 1/Q(s,r;t) = ∂t*(s,r;t)/∂t; performing a first migration on D(s,r;t) to generate common image point (CIP) gathers G(x,h) wherein x is subsurface image point and h is angle or offset; performing a second migration on D(s,r;t) * 1/Q(s,r;t) to generate weighted common image point (CIP) gathers G1/Q(x,h); and calculating a conditioned ratio of the weighted CIP gathers G1/Q(x,h) over the CIP gathers G(x,h) to get CIP gathers of 1/Q(x,h) is disclosed.

摘要： A method is described for of creating a high-resolution earth model of a geological medium. The method includes generating a long-wavelength anisotropic velocity model using tomographic inversion of seismic data gathers, accessing an anisotropic attenuation model, and correlating the long-wavelength velocity model with the anisotropic attenuation model to produce a long-wavelength velocity and attenuation model. The method further includes performing prestack depth migration on the seismic data gathers using the long-wavelength velocity and attenuation model to produce seismic image gathers, applying a dip-consistent filter to the seismic image gathers, and transforming the one or more filtered seismic image gathers to the time domain. The method further includes generating a full-band impedance model by performing impedance inversion of the filtered seismic image gathers in the time domain using the long-wavelength velocity and attenuation model. The full-band impedance model is used for detecting fluid pressure anomalies in the geological medium.
