This is an older blog post, you will find one on more recent data here
This interactive presentation contains the latest gas production data from all 3217 horizontal wells in Louisiana, that started production since 2007, through July.
Gas production in Louisiana, with the Haynesville basin being the largest contributor, is rising in 2017 at its strongest pace since 2011. As you can see from the above chart, production from especially older wells is suddenly growing again. The reason behind this is that operators are returning to the Haynesville to refrack these existing wells.
If you go to the 3rd tab (“Well quality”), you can see this in more detail. The end of the tails of the production curves from the 2008-2011 vintages are jumping upwards.
Another interesting finding is that newer wells are far more productive than older wells. As you can see in the bottom graph of that overview, the average 2016 well has produced more gas cumulatively before 20 months on production, than the total cumulative production from any of the earlier vintages (on average).
The ‘Advanced Insights’ presentation is displayed below:
This “Ultimate Return” overview shows these recent improvements even more extensively. Wells are grouped by the month in which they started production. Although the chart looks messy due to the great number of curves, if you go through the list and click on any of the recent months, you’ll see that all those curves on the top are from wells that started some time since the middle of last year. They’re obviously on track to greater recoveries than the earlier wells during the original boom in the Haynesville.
The “Cumulative production ranking” tab ranks all these wells according to cumulative gas production. Individual well production is estimated from lease production, and well status data (including regular well tests) in Louisiana as well level production data is not available. If you go through the list, you’ll see that almost 20 wells have now recovered more than 10 Bcf each.
By Wednesday next week I should have another post on the Niobrara ready.
Production data is subject to revisions. For this presentation, I used data gathered from the following sources:
- The Louisiana Department of Natural Resources
The above presentations have many interactive features:
- You can click through the blocks on the top to see the slides.
- Each slide has filters that can be set, e.g. to select individual or groups of operators. You can first click “all” to deselect all items. You have to click the “apply” button at the bottom to enforce the changes. After that, click anywhere on the presentation.
- Tooltips are shown by just hovering the mouse over parts of the presentation.
- You can move the map around, and zoom in/out.
- By clicking on the legend you can highlight selected items.
- Note that filters have to be set for each tab separately.
- The operator who currently owns the well is designated by “operator (current)”. The operator who operated a well in a past month is designated by “operator (actual)”. This distinction is useful when the ownership of a well changed over time.
- If you have any questions on how to use the interactivity, or how to analyze specific questions, please don’t hesitate to ask.
