P90 relates to proven reserves, P50 relates to proven plus probable reserves and finally P10 relates to proven, probable and possible reserves
What is P10 in statistics?
There should be at least a 10% (P10) probability that actual quantities recycled will be equal to or greater than the upper estimate
What does the P90 rating mean?
90% P90 P90 represents the cost of the project with sufficient funding to provide a 90% level of confidence in the results. There is a 90% probability that the final cost of the project will not exceed the funding provided
What does the P90 metric mean?
A percentile is a very useful performance test metric that gives a measure below which a percentage of the sample falls. For example, the 90th percentile (abbreviated as p90) indicates that 90% of the sample is below this value and the remaining values (that is, the remaining 10%) are above i
What are P90 and P50?
Basic Definitions. P50 and P90 are probabilities. The P50 figure is the annual average production level at which production is expected to be exceeded by 50% over a year. The P90 number is the level of annual production that should be exceeded by 90% in a year
What is the estimate of P10?
There must be a probability of at least 10% (P10) that the quantities actually recycled will be equal to or greater than the upper estimate.
What is the average of P10 P50 P90?
For reserve estimation purposes, National Instrument 51-101 (NI 51-101) defines P10, P50 and P90 (ROBINSON et al., 2004). P90 denotes proven reserves, P50 denotes proven plus probable reserves and finally P10 denotes proved, probable and possible reserves.
What is P10 P90 in percentile?
This is a good average estimate. The mean and expectation (same level of measurement, just different names) in oilfield assessments are usually around the P40P30 values and are therefore high estimates. P90 and P10 are the low and high estimates, respectively. P90 means that 90% of the estimates exceed the P90 estimate.
Is the P10 better than the P90?
In the oil and gas industry, P90 should be at least a 90% probability that actual amounts recovered will be equal to or greater than the low estimate. P50 should be at least a 50% probability that the amounts actually won will be equal to or greater than the best estimate P10 should be at least a 10% probability that the…
What is the p99 metric?
Latency P99: The 99th percentile of latency. This means that 99% of the requests are faster than the specified latency number
What is p50 and p90 latency?
A p50 metric represents the average performance of the system. In this case, the p50 metric is 18 ms, meaning 50% of users experienced this latency or less. The p90 measurement is 122, which means that 9 of the 10 measured latencies are below 122
What do p95 and p99 mean?
Query latency is reported in milliseconds, and the p95 and p99 values are the 95th and 99th percentile values (a p99 query latency value of 500 ms means that 99 out of 100 queries took 500 ms or less to complete). It says 99 out of 100 requests took 500 ms or less
What does P90 mean in solar energy?
P90 production means that there is a 90% probability that production will be at least the specified amount in a given year. This means that there is only a 10% chance that production will be below the specified amount.
What does P50 in the wind mean?
A P50 estimate is the median rate of return typically used to determine equity case, and. As a performance assumption in the base case of the lender, a P90 case is usually used, which corresponds to the expected initial performance with a probability of 90% being exceeded.
What is a P90 value?
P90 represents a more conservative part of the same distribution. A P90 value is a value that will be met or exceeded 90% of the time. For example, if the P90 power is 1,000 kWh, this means that there is a 90% chance that the generator will produce 1,000 kWh or more each year.
What is the P90 wind?
P90 is the energy that WMI forecasts that a wind turbine will produce 90% in an average year, accounting for uncertainties in measurement, analysis and operation of the wind turbine. P50, on the other hand, is the projected average annual energy yield for your site, the annual energy yield you are most likely to achieve.
