Bridging over Uncertainty: Past Performance into Forecasting
Paper Abstract 6/21/2005

Engineers tend to be more deterministic. With the ever growing challenges of decision making and risk assessment associated with huge investments, the “need” to realize many (or even all) objectives of the business endeavor becomes crucial. Expecting probable outcomes of a future process yet to leave them comfortable in using just determinism.

However, scientific/technical education drives us to spend more time and money to get closer to “The Answer”. This leads naturally to deterministic conservative estimates, possibly false precision and frequent surprises.

This presentation aims to design the concept of modeling the existing data into visualized tools to help in predicting the future. Engineers should use the Monte Carlo Simulation, Decision Trees, Data Bases, Expert Systems, Linear Programming, Design of Experiments and all types of Artificial intelligence to state their uncertainties not as discrete values, but as continuous ranges. G&G, reserves estimates, development planes, operations, EOR or IOR, and economics are vast areas to apply these techniques.

How high are the “highs” and how low are the “lows” and when they occur are difficult to predict. So let us put our past experience on an updated form to be an ongoing process to help currently in minimizing uncertainties and to include future knowledge.

One of the already proved approaches to tackle uncertainty is the multidisciplinary team. However, members of this team have to unify first their views, thoughts, and sometimes even units!!! They’re also requested to use each available visualization tool; experimenting sensitivity analysis to define the way for process optimization.
