Abstract: A method for geological formation analysis may include collecting time-lapsed well-based measurement data from a first borehole in a geological formation over a measurement time period, and collecting time-lapsed electromagnetic (EM) cross-well measurement data via a plurality of spaced-apart second boreholes in the geological formation over the measurement time period. The method may further include determining simulated changes to a hydrocarbon resource in the geological formation over the measurement time period based upon a geological model using a processor, and using the processor to determine if the simulated changes are within an error threshold of the time-lapsed well-based measurement data and the time-lapsed cross-well EM measurement data. If the simulated changes are not within the error threshold, then the geological model may be updated.

Abstract translation: 用于地质构造分析的方法可以包括在测量时间段内收集来自地质构造中的第一钻孔的基于时间的井测量数据，以及通过多个间隔收集经过时间的电磁（EM）交叉井测量数据 在测量时间段内在地质构造中铺设第二个钻孔。 该方法还可以包括基于使用处理器的地质模型来确定测量时间段上的地质构造中的烃资源的模拟变化，并且使用处理器来确定模拟变化是否在经过时间的错误阈值内 基于良好的测量数据和经过时间的交叉井EM测量数据。 如果模拟的变化不在误差阈值内，则可以更新地质模型。
