Calibration of Uncertainty (P10/P90) in Exploration Prospects* Robert Otis 1 and to determine an appropriate P10/P90 (P10 P90 ratio) for both EUR (Estimated 18 DHIs Post Drill Mean/Pre Drill P50 - Area P99 P98 P10/P90 Calibration&

This will automatically calculate a P10, P50, P70 and P90 for you for any amount of data entered. Alternately, you can calculate a P90 in excel yourself. You need to find the mean and standard deviation for all your simulated values.

Cooper Energy Investor Series Cumulative Probability – P90, P50, P10 The terms P90, P50 and P10 are occasionally used by persons when. The forecasts are therefore likely conservative because transitional flow 17 Jun 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 Low Estimate = Proved Reserves, Best and High. Estimate = Unproved Reserves . 30. Page 30.

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.

The problem is now to establish the 2 parameters of this Gaussian distribution, i.e. the Mean value and the Variance (named sigma or RMS). Given P10-P50-P90 points from a distribution, how can we sample from that distribution. Create presentation quality cumulative distribution graphs (CDFs) o Defining minimum, maximum and most likely cost values and including relevant risks will allow you to define P10, P50 and P90 cost estimates. Understanding the potential ranges of your cost estimate will allow you to define a suitable level of contingency that takes into … SPE 162711 Using Production Data to Generate P10, P50 and P90 Type-Curves for Shale Gas Prospects J.D. Williams-Kovacs, University of Calgary and TAQA North Ltd, C.R. Clarkson, University of Calgary So, in our sample, P10 would be 96 – 10% of our observation will exceed the value of 96. And P90 will be 94 – 90% of our observation will exceed the value of 94. Note that it does not mean that the estimate has a 90% chance of occurring – that is a very different concept.

plots are commonly used in the oil and gas ind ustry to calculate P10, P50 and P90 values o f key probabilistic statistics such as one year cumulative gas produced and reserves for a given field. technical certainty: a low estimate, best estimate and high estimate. While probabilistic assessments are not commonly applied, it is generally accepted that the equivalent estimates on a cumulative probability distribution would be greater than or equal to P90, P50 and P10 respectively. For discovered and commercial volume estimates, the •If Probabilistic, P90%, P50% and P10% •If deterministic, technical definitions same as reserves except they are not currently producible. Low Estimate = Proved Reserves, Best and High Estimate = … The P50 - P90 evaluation is a probabilistic approach for the interpretation of the simulation results over several years..

P50 is the most probable value, also called best estimate, and it can be exceeded with 50% probability. P90 is to be exceeded with 90% probability, and it is considered as a conservative estimate.

Cumulative P10 is a low, pessimistic estimate, and cumulative P90 is a high estimate. Both exceedance and cumulative probabilities are commonly used.
