Watercut WΣW History Matching @model predicts production adjustments coefficients \alpha_W(t), \ \alpha_O(t) from WΣW plot.
The production adjustments coefficients \alpha_W(t), \ \alpha_O(t)
| ||
|
The production adjustments coefficients \alpha_W(t), \ \alpha_O(t) can be found from minimisation of the goal function:
|
where D is the distance between each historical point and model curve on WΣW plot.
|
and \min D \big( P_{\rm mod}}, P_{\rm hist} \big) means minimal distance between point P_{\rm hist} = \big( ΣWOR_{\rm hist} , WOR_{\rm hist} \big) and the model curve P_{\rm mod} = \big( ΣWOR_{\rm mod} , WOR_{\rm mod} \big)
The results of the history matching are illustrated on Fig. 1 below.
