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 (7055) horizontal wells in Pennsylvania since 2010, through October. Ohio data through September is included, though by default deselected (use the “basin” selection to include it).
Gas production from these wells dropped for the 2nd month in October, and made a new low in 2016 at just above 13 BCF/day. The shut-in of older wells appears to have caused at least part of this decline.
In the last tab (“Top operators”), we can see that Cabot has taken over the leading producer position from Chesapeake.
The new ‘Advanced Insights’ presentation is displayed below:
This “Ultimate recovery” overview shows the relationship between gas production rates, and cumulative gas production, for all the wells that started production in a specific quarter.
If you cycle through the quarters since the 2nd half of 2014 (by clicking on the quarters in the legend), you’ll notice that average well productivity appears to have stagnated since then.
The next 2 sheets in this presentation are new :
In the “Cumulative production ranking”, you’ll find the ranking of all wells by cumulative gas production. This makes it easy to find the wells that have produced the most (or least) so far. If you change the ranking to “Operator (current)”, you can see the ranking of all operators, based on cumulative production through October. Tooltips are available with more information.
The “Well status map” overview is meant to show geographically the status of all these horizontal wells. You can cycle through time using the slider at the top. For each month you’ll see the status of all selected wells on the map. This makes it easier to locate where wells have been spud, completed, or plugged for example.
For a more detailed description of the other overviews in this presentation, please visit the first version of this advanced presentation for ND available here.
For this presentation, I used data gathered from the following sources:
- Ohio Department of Natural Resources
- Pennsylvania Department of Environmental Protection
The above presentation has 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, and include or exclude categories.
- 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.
