Eagle Ford Output Estimate and Future Scenario

D Coyne 101 Comments

Eagle Ford output is difficult to estimate as there are 20-25 separate fields that need to be followed to get a full picture. To save time, I have used Enno Peters’ data for horizontal wells from Districts 1 to 5 in Texas from his website shaleprofile.com, he has data through June.  Enno’s data is combined with the RRC data for statewide C+C output to find the percentage of Texas C+C from the Eagle Ford. This percentage is multiplied by Dean’s estimate for Texas C+C output to get the following estimate, which is compared with Enno Peters’ data.  EF-EP is Enno Peter’s collection of data from the RRC, EF-DC is my estimate using the method described.  Based on a May 2016 Eagle Ford estimate, I subtract 70 kb/d from the EF-DC estimate to account for non-Eagle Ford horizontal well output in Districts 1 to 5

Mexico, China and Beyond

Mexico, China and Beyond

Ron Patterson’s post asking if China’s oil production has peaked reminded me of Mexico
which also produces mainly from supergiant fields. Mexico’s oil production peaked in 2004 and has averaged a 3.5 percent per annum decline rate since, with a peak yearly decline rate of 9 percent in 2008. China’s oil production has fallen 10% from its peak in 2015. Part of that is oil price-related as the Daqing oil field has an operating cost of $46 per barrel and could reverse as the oil price rises. The comparison of China and Mexico with a projection to 2023 is shown in the following figure:

Texas Petroleum Report – July 2016 and LTO scenarios

I have attempted to correct the reported Texas output using the methodology provided by Dean. Usually Dean provides the spreadsheets and I simply reproduce his charts with a few comments.  This month Dean may be on vacation or busy and I have not yet received his input. If I get his charts I will post them.

Dean uses the average of the correction factors from Jan 2014 to the present in order to reduce the month to month volatility of the correction factors.  I tried several averaging methods (all data, 12 month average, 6 month average, and 3 month average) where for the x month average the most recent x months of correction factors were averaged.

The only method with a significant difference was the 3 month average, so I present the “corrected” output using Dean’s usual method and an “Alt (3 month)” alternative. The RRC data and the EIA estimate are also included for reference.

Petroleum Supply Monthly, Texas C+C estimate, Permian, and Eagle Ford

D Coyne 561 Comments

This post was written by Dennis Coyne and does not necessarily reflect the opinion of Ron Patterson.

I have considered an alternative way of estimating Texas oil (C+C) output using the Drilling info data provided in the EIA’s 914 monthly production reports.

The Texas estimate is a weak part of the EIA’s estimate for US C+C output. In the chart above I show the EIA’s most recent monthly estimate from the Petroleum supply monthly and compare with an alternative estimate that substitute’s my best estimate for EIA’s TX C+C estimate. The slope of the trend line needs to be multiplied by 366 to give the decline at an annual rate, for the EIA estimate it is 528 kb/d per year, and for the alternative estimate it is 364 kb/d per year.
