How Unknown Population Distribution Will Impact EUR and Type Wells

Join us for a Live 30 minute Webinar followed by a 15 minute Q&A Session.

In Part I, Fooled by Minimum Well Count, we observed that it was highly unlikely that the minimum well count would result in a probability distribution that represented the population and that the important minimum is not the number of wells in the sample, but the number of wells being drilled.

Part II will describe a method to determine an inventory of possible population distributions and will show the effect that not knowing the true population distribution can have on probabilistic reserve estimates. You will leave understanding that no matter how many wells are drilled, the proven reserve will never converge to the mean and that conventional wisdom results in overestimation of proved reserves.

What will you learn?

  • Possible population distributions discussed in Part I are not reliable.
  • A better way to calculate population distributions.
  • A Monte Carlo process to estimate population and well count adjusted probability-based estimates for EUR.
  • For large well counts, EUR does not converge to the mean.
