... was observed after 26-28 months, which is now stabilized at 600–800 ppm in congruence with the WC. Although as indicated by laboratory experiments, polymer retention in core material is high; ~70% of the injected polymer propagates without any delay, while the remaining 30% tails over several PVs.

... model that enables evaluations of different alternative field development scenarios. Mattax and Dalton (1990) illustrate procedures to improve an assisted history matching by minimizing the misfit of production data. Frequently, this process is done directly in the numerical model, yielding...

... Given this problem statement, the objective of deconvolution is to identify the ‘best’ values or estimates z ^ of z such that, when introduced into Eq. 2 , we obtain estimates Δ p ^ that are as close as possible to the observed pressure drop history, Δ p , while...

..., thereby aiding well-level history matching and high-resolution updates of modern geologic models. This work presents, for the first time, an application of the Generalized Travel Time Inversion (GTTI) to dual-permeability models of naturally fractured reservoirs. This is facilitated by a simplified, yet...

... Abstract Unconventional reservoirs typically exhibit large uncertainty in rock and fracture properties coupled with significant heterogeneity making manual history matching a challenging endeavor. Computer-assisted methods of history matching gained preference because they honor the non...

These WPs are from 4 different pads, in close proximity to one another, producing from reservoir of different qualities from Jackfish 1 SAGD project; they have more than 1700 days of history (from first steam to end of July 2013). It is seen that reservoir quality has...
