P50 means there is a 50% chance in any given year that production will be at least a specific amount. If an array has a P50 production level of 500 kWh, it means that on any given year there is a 50% chance that production will be AT LEAST 500 kWh.

This ratio uniquely determines the more traditional standard deviationor variance, but is more easily understood when describing uncertainty in exploration resource estimation.

2016-05-31 · Does my forecast always have to result in a high (P10)/best (P50)/low (P90) estimate of the ultimate recovery? There are many situations, where the model objectives dictate another objective function than ultimate recovery; however, the forecaster should always plan for making a P10/P50/P90 forecast that is consistent with the resource estimates in addition to the primary objectives of the study. In the end, I want to calculate other columns with p10, p50 and p90 values as in the attached picture. p10 and 90 are the dash lines and p50 is the solid red line.

Mean = 0.30 * P10 + 0.40 * P50 + 0.30 * P90. It is applicable to a lognormal distribution, if the variance is not too great. Now the question is "what is too great?". A simple rule is to calculate the ratio (P10 - P50) / (P50 - P90) For a true lognormal distribution, Swanson will give a too low mean.

I want to use P10, P50 and P90 values as input to: A) generate a probability density function (This feels like a Myerson distribution, but I can't figure out how to do that in Python. There's an ad

Compared to other single coil designs, such as the ubiquitous Fender single coil, the bobbin for a P-90 is wider but shorter. Lets take a look at the below graph.

As the P50 was made before the Breeze 2 facility went into service, it is a smooth line. The highest line on the graph must be the P50 case. When computing P90, you should realise that the P90 will be below the P50. The P90 in a sense lowers the production level until you can be sure that you obtain a 90 percent change of being correct.

This paper discusses a new tool that was developed specifically for generating probabilistic (P10, P50 and P90) 1 type curves for shale plays, based on a series of input production wells, which can be used in the early stages of the stochastic analysis of shale gas prospects.

P50 (and P90, Mean, Expected and P10) When probabilistic Monte Carlo type evaluations are adopted, this is a statistical confidence level for an estimate.
