SBIR Phase II: Parallel Processing of Time-Lapse Seismic Data Via the Internet

该小型企业创新研究（SBIR）第二阶段项目涉及在并行计算机上处理和分析时移地震数据，使用互联网控制处理流程并可视化结果。 近年来，时移地震项目活动呈指数增长。 时移地震分析通过对储层中随时间的流体运动进行成像来促进油气储层的管理。 结果用于指导油藏管理决策，例如在何处部署新井或在何处注入水、天然气或蒸汽以刺激油气运动，并帮助最大限度地延长新油田和现有油田的寿命，同时最大限度地降低开采成本。 处理时移地震数据所需的计算机算法是复杂的，需要先进的计算硬件，通常是多处理器Unix工作站或个人计算机集群，许多潜在的客户没有。 拟议的创新将允许客户在集中的PC集群上处理他们的数据，使用互联网来控制处理并远程可视化结果。 拟议的创新将改善时间推移地震工作流程的组成部分之间的联系，导致更好的理解和更广泛的商业接受的technology.Potential应用的研究提出的第四波成像包括石油工业绘图的过油，昂贵的注入流体的监测，成像流动划分和断层和裂缝的水力特性。 非石油应用包括监测地下水储量、污染物羽流的地下监测和环境清理项目。 为该项目开发的基于网络的并行软件系统可应用于其他计算机密集型领域，如地震学、医学和卫星成像。 来自这个基于网络的软件平台的工具，例如用于建模岩石物理学和地震数据的工具，也可用于教育目的。

This Small Business Innovation Research (SBIR) Phase II project concerns the processing and analysis of time-lapse seismic data on parallel computers, using the Internet to control the processing flow and visualize the results. In recent years, there has been exponential growth in time-lapse seismic project activity. Time-lapse seismic analysis facilitates the management of oil and gas reservoirs by imaging fluid movement in the reservoir over time. The results are used to guide reservoir management decisions-such as where to place a new well or where to inject water, gas, or steam to stimulate hydrocarbon movement-and help maximize the life of both new and existing fields while minimizing recovery costs. The computer algorithms needed to process time-lapse seismic data are complex and require advanced computational hardware-typically multiprocessor Unix workstations or clusters of personal computers-that many potential customers do not have. The proposed innovation will allow customers to process their data on a centralized PC cluster, using the Internet to control the processing and to visualize the results remotely. The proposed innovation will improve the links between the components of the time-lapse seismic workflow, leading to greater understanding and more widespread commercial acceptance of the technology.Potential applications of the research proposed by Fourth Wave Imaging include petroleum industry mapping of by passed oil, monitoring of costly injected fluids, and imaging flow compartmentalization and the hydraulic properties of faults and fractures. Non-petroleum applications include monitoring groundwater reserves, subsurface monitoring of contaminant plumes and environmental clean-up projects. The web-based parallel software system developed for this project could be applied to other computer-intensive fields such as earthquake seismology and medical and satellite imaging. Tools from this web-based software platform such as those for modeling rock physics and seismic data may also be useful for educational purposes.
