    • A method for estimating a volume of a stimulated reservoir includes receiving a seismic signal from each microseismic event in a plurality of microseismic events in an earth formation by an array of seismic receivers. The method further includes representing each microseismic event by a plurality of markers in the three-dimensional space. A spatial distribution of the markers represents a volume of rock influenced by a microseismic event, wherein the volume and a location of each event are derived from the seismic signal. The method further includes calculating a scalar attribute for each marker in the plurality of markers, dividing the three-dimensional space into a plurality of three-dimensional grid cells, and summing the scalar attributes for all the markers in each grid cell to provide a total scalar attribute for each grid cell.
    • 用于估计受刺激储层的体积的方法包括:通过地震接收器阵列在地层中的多个微震事件中从每个微震事件接收地震信号。 该方法还包括通过三维空间中的多个标记表示每个微震事件。 标记的空间分布表示受微震事件影响的岩石体积,其中每个事件的体积和位置是从地震信号导出的。 该方法还包括计算多个标记中每个标记的标量属性,将三维空间划分为多个三维网格单元,并对每个网格单元中所有标记的标量属性求和,以提供总数 每个网格单元的标量属性。
