Something has been bugging me the last couple of days, and no, it's not IJWT adopting a more negative tone. He's perfectly entitled to his views, as everyone else is.
What is bugging me are the principles behind P90, P50 and P10 calculations. Being a relative novice to O&G exploration, we all place a great deal of weight on whether something has a 90% or 50% or 10% chance of success. And we appear to take those numbers as gospel. Even though the numbers are created by humans with their inherent biases to the positive or negative.
It then got me thinking whether statistically speaking reported P10s are actually only true 10% of the time or not. Or are P10s really P5s or P1s. Likewise are P50s over exaggerated or under played. Etc.
Is anyone aware of any studies in this space or had any real life examples of discoveries being far off those statistical calculations? Either to the upside or downside?
Or am I just overthinking the whole thing and should just chill and watch the story unfold further?
Thoughts?
