Let's see a couple of practical examples (I can share the data if someone is interested).
Definitely interested in helping solve this one so feel free to email the data (obviously not 1,000 Eclipse smspec and unsmry files although I can handle that without any problems).
It's 1 TB of data and my script took almost 4 hours in parallel on 4 processor over a network to reduce that huge amount of data to a tiny 406x7 matrix... but anyway, I'll see if I have the permission of posting the data and I'll let you know. I could really use some suggestions... or maybe a good kick in my a** telling me I am doing a bunch of stupid things.
Example 1
# o2 and o3 are the number of production wells, split into 2 # different categories # inj is the number of injection wells # fomts is the final oil recovery
rbf = Rbf(oilPlateau, gasPlateau, gasInjPlateau, o2, o3, inj, fomts)
op = [50380] gp = [103014000] gi = [53151000] o2w = [45] o3w = [20] inw = [15]
I take it all your inputs are float arrays? i.e. you just consider number of production wells as a floating point value.
They are floats, but it doesn't really matter as RBFs should treat them all as floats. My results are the same whether I use "45" or "45.0".
I suppose strictly speaking o2 and o3 are not independent of eachother but I would guess that for the purposes of using Rbf it wouldn't be an issue.
They are independent: they are 2 completely different kind of wells, o2 will give you much more gas while o3 much more oil. It turns out that all interpolation methods *except* "linear" fail miserably with huge errors even when I use exactly the same input points as the original data points. If I use the "linear" interpolator, I get errors in the range of -1.16305401154e-005 1.29984131475e-006 In percentage, which is very good :-D. Unfortunately, when I input even a single parameter value that is not in the original set, I still get these non-physical results of oil production increasing when I decrease the number of wells...
