Seems to underscore the high depletion issues that have been discussed in the past on this site and other venues
Mark, take a look at the comments; Mike Shellman - a small O&G operator, in business for years.
Thank you for posting this; I found the info quite interesting and informative.
I recall Mark P's prescient discussion of the EF' steep decline rate, back in 2013-14.
Glancing at the graph, decline rate appears to remain relatively constant, regardless of initial production date or initial production value (percentages are rough visual guestimates only):
Year 1: -60% for the year, -60% cumulative decline, 40% remaining reserves
Year 1: -50% for the year, -80% cumulative decline, 20% remaining reserves
Year 1: -50% for the year, -90% cumulative decline, 10% remaining reserves
Just my two cents, and worth every penny.
Thanks again for sharing the info,
