SPEE Guidelines Don’t Guarantee a Reliable Type Well?

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

SPEE Monograph 3 provides guidance towards the minimum number of wells (sample size) required for a reliable type well. Missing from the guidance is an understanding that type well reliability depends on the number of sample wells and the number of wells that will be drilled using the type well. The talk will demonstrate how the guidance was determined, explore reasons why the sample wells may not represent the wells you plan to drill and pique your curiosity as to whether probability distribution might be a better confidence criterion than mean for confidence.

We draw two important conclusions:

  • SPEE guidelines tell the number of wells needed to reproduce the mean of a known probability distribution. This is not the same as having a reliable type well.
  • It is unlikely that a sample distribution will represent future wells.

What will you learn?

  • The wells you drilled probably won’t represent the wells you plan to drill.
  • SPEE recommended well count for type wells may not be suitable.
  • Mean is not a good choice for deciding minimum well count for type wells.
