    • Implementations of discontinuity detection are described. In one possible embodiment, information associated with a computer-generated model is accessed. A location associated with a feature in the model can be reviewed for possible discontinuity properties by comparing an orientation associated with the location to an orientation of a true normal to the feature associated with a specific point nearby the location. In one possible aspect, if the orientation associated with the location and the true normal are within a given range of one another, the location can be flagged as a possible discontinuity in the feature.
    • 描述不连续检测的实现。 在一个可能的实施例中,访问与计算机生成的模型相关联的信息。 可以通过将与位置相关联的方向与与该位置附近的特定点相关联的特征的真正法线的方向进行比较来审查与模型中的特征相关联的位置的可能的不连续性。 在一个可能的方面,如果与位置和真正法线相关联的方向在彼此的给定范围内,则该位置可以被标记为特征中的可能的不连续性。

    • Systems and methods perform consistent dip estimation for seismic imaging. An example system applies global consistency constraints during iterative volume dip estimation of a seismic volume to improve upon conventional dip estimation methods. With each iteration, the system applies single and joint dip constraints, checking local dip estimates for reciprocity, causality, consistency, and vertical and lateral continuity. At discontinuities in the seismic volume, local divergences are marked with a quality attribute. Upon convergence of the volume dip estimation, the volume may be rendered in 3D, including the discontinuities. In performing volume dip estimation, the system can also provide automatic horizon interpretation and automatic fault detection.
    • 系统和方法对地震成像执行一致的倾角估计。 示例系统在地震体积的迭代体积倾倒估计期间应用全局一致性约束,以改进常规倾角估计方法。 通过每次迭代,系统应用单一和联合倾角约束,检查本地倾斜估计的互惠性,因果关系,一致性以及垂直和横向连续性。 在地震体积的不连续性中,局部差异标有质量属性。 当收敛于体积下降估计时,体积可以以3D形式呈现,包括不连续性。 在进行体积下降估计时,系统还可以提供自动水平解读和自动故障检测。

    • Implementations of various technologies for a method for processing seismic data. In one implementation, the method includes (a) selecting a first trace from a first seismic data set and a second trace from a second seismic data set; (b) extracting one or more features of the same types from the first trace and the second trace; (c) matching the extracted features from the first trace with the extracted features from the second trace; and (d) calculating for a displacement field using one or more of the matching features of the first trace and the second trace.
