and OPEX estimates combined with robust benchmarking and testing of different cost options. Cost risk analysis Using standard industry risk software, ‘@Risk’, Petrofac will perform Monte Carlo simulations for an estimate to provide P10, P50 and P90 type estimates as part of the overall project risk assessment process. Our customers

P50 (0.5) - The true value is expected to be lower than the predicted value 50% of the time. This is also known as the median forecast. By definition, P10, P50 and P90 are values on an ascending or descending scale, representing the point where the integral (total area) from one end of the statistical curve to the define value would have equaled to 10%, 50% and 90% of the total area respectively. Specifically, there will be a P10, P50, and P90 forecast. These forecasts are automatically exported to the Analysis Manager, where they can be viewed from other worksheets, such as forecast or decline worksheets. When a risk simulation is re-run, these forecasts update with the most recent results. technical certainty: a low estimate, best estimate and high estimate.

P50 is defined as 50% of estimates exceed the P50 estimate (and by definition, 50% of estimates are less than the P50 estimate). It is a good middle estimate. Cumulative P10 is a low, pessimistic estimate, and cumulative P90 is a high estimate.

Jun 17, 2008 For the purpose of reserve estimation, National Instrument 51–101 (NI 51–101) defines P10, P50 and P90 (ROBINSON et al, 2004). P90 refers

Then the software will come out with the PDF of the distribution. How is this actually done?

The central limit theorem indicates that the P50 estimate has more chance of occurring than the P90 and P10 estimates.

The P50 - P90 evaluation is a probabilistic approach for the interpretation of the simulation results over several years.. This requires several additional parameters, which are not provided by the simulation process, and should be specified (assumed) by the user.. Procedure. For activating the P50/P90 tool, please open the button "Energy Management", page "P50-P90 estimation" in the grid's

Both define the reserves and resources estimates in terms of P90/P50/P10 ranges : Cooper Energy Investor Series Cumulative Probability – P90, P50, P10 The terms P90, P50 and P10 are occasionally used by persons when. As mentioned before, uncertainty is composed of several factors, so one thing we should keep in mind is working at the same exceedance level when combining them. 2013-11-19 · Actual / Estimate Cost Ratio The P50 cost value is a probabilistic estimate of the project cost based on a 50% probability that the cost will be exceeded. Cost Estimate Performance 200% 180% P10 P50 P90 160% 140% 120% 100% 80% 60% 40% 20% 0% Projects of a portfolio are considered at the mean of a simulated cost distribution, typically the P50 estimate. 6 Increase P10/P90 Hold P99 Increase P10/P90 Hold P50 Increase P10/P90 No Change Needed Presenter’s notes:Ways to correct problems related to P01, P50 and P10/P90 as parameters used to estimate lognormal distributions. 10 P10, P50 and P90 are cost (in this case) estimates that assume different different levels of risk turning bad. Each is more pessimistic than the last.

Alternately, you can calculate a P90 in excel yourself. You need to find the mean and standard deviation for all your simulated values. A popular means of specifying a particular distribution is to indicate P10 and P90, along with a measure of central tendency such as either P50 or the mode of the distribution.
