Taking into Account Uncertainty on Fairway Borders for Lateral Offset Stacked Channels (LOSCs) Simulations

Among the process-based methods, the Lateral Offset Channels (LOSCs) simulation method has been especially designed to simulate logical chronological sequences of channels. The last (most recent) channel observed on spectral maps is fitted with a B-spline. To simulate the older channels in the sequence, the control points of the B-spline are moved along a parabolic path towards the fairway centerline, thus modifying the original B-spline in a logical way. In this paper, we particularly emphasize on the uncertainty on the fairway borders and show how actual borders corresponding to various scenarios can be drawn and how the channels simulation is adapted accordingly. In particular, we show on a field case that a larger fairway results in more meandering channels than a narrower one. All channels in a sequence are consistent with each other and can be conditioned to well data.
