Eliminate Type Curve Survivor Bias

✓ Compatible with desktop and web



This Spotfire template helps you eliminate survivor bias when generating type curves. Survivor bias is a common problem when generating type curves. Type curves are normalized on a time basis, so wells with longer production histories, i.e. the “survivors”, bias the type curve calculation later in life. These older wells may have different production profiles than the recent wells, which can significantly affect EUR. It’s important to correct the input data so your type curves aren’t biased, over or underestimating the EUR. This Spotfire template provides a fast, easy and visual method for doing this.


  • Interactive and quick method for observing how longer-life wells affect type curves.
  • Property control inputs for well count and production history thresholds
  • Use DCA Wrangler to quickly generate type curves
