For example, facilities engineers typically develop an arbitrary design case (i.e. a snapshot in time), which is some combination of the worst possible scenarios of each of the key inputs, such as reservoir temperatures and well deliverability, each of these inputs having uncertainty associated with them. As many modern production system designs are for deeper water and longer step-outs, making them economically marginal, assuming the arbitrary worst design case no longer seems appropriate and understanding the effect of uncertainty on the design becomes increasingly important.
