Using Non-Stationary Training Images from Process-Based Models for Multiple Point Geostatistics Stochastic Generation of Fluvial-Dominated Delta Reservoir Model

Process-based method forward stratigraphic modelling provides advantages in reservoir modelling by simulating the geological process mathematically, and the genesis of geologic formations over time (Michael et al., 2010). In spite of its advantages, Miller et al. (2008) have recognised significant challenges in process-based simulation models,...

Phase estimation of recurring patterns in nonstationary signals

A phase estimation algorithm is presented to estimate the phase of a recurring pattern in a nonstationary signal. The signal is modelled by a template signal that represents one revolution of the recurring pattern, and that the frequency of this pattern can change at any time with no assumptions about local stationarity. The algorithm uses a...
