    • The present relates generally to the field of quantitative sedimentologic and stratigraphic prediction in which errors, uncertainties, risk and accuracy are calculated. Specifically, geologic data observed or inferred from core, outcrop, well log and/or seismic data from particular locations, in conjunction with a stratigraphic forward model and an optimization technique (mathematical inverse algorithm), are used to predict stratigraphic and sedimentologic attributes at locations other than those at which data were collected. This is accomplished by inverting a stratigraphic/sedimentologic forward model with simultaneous multi-parameter inversion or other mathematical optimization technique, such that forward model predictions are forced to obtain a best match with observations. The geologic data used to constrain the inversion are a small sample set of the larger, complete, rock volume simulated by the model.
    • 本发明一般涉及计量误差,不确定性,风险和准确性的定量沉积学和地层学预测领域。 具体来说,结合地层正演模型和优化技术(数学逆算法),从核心,露头,测井和/或地震数据中观察或推断出的地质资料,用于预测地理位置和地层特征 除了收集数据之外。 这是通过使用同时多参数反演或其他数学优化技术来反演地层/沉积学前向模型来实现的,使得前向模型预测被迫获得与观测结果的最佳匹配。 用于约束反演的地质数据是由该模型模拟的较大,完整的岩石体积的小样本集。
