![]() Just 15 wells out of 21,580 producing conventional wells in this chart were drilled in 2021.Įxactly one conventional well had production higher than the average unconventional well the Babcock 1 well in Swissvale, Allegheny County and operated by R Harris Gas & Oil Inc produced 854 MMcf, or about four times as much gas as the runner-up in the category. This is probably accurate – while conventional drilling didn’t entirely stop with the arrival of the unconventional drilling practices, it has dropped off precipitously. The distribution shows a cluster of wells that are around 5,000 days old, with a noticeable vertical grouping around that age. ![]() There are a couple of other notable features about this scatter plot. Figure 1 shows us that the mean gas production for these wells is 1,207 Mcf (about 1.2 MMcf), which is just barely off of the bottom margin of the graph. ![]() This seems like it was probably entered as a dummy date somewhere along the way. The oldest well here is listed at 44,561 days, which works out to January 1, 1900. The first difference that sticks out is the scale, as this is measured in Mcf rather than Bcf, and the scale showing the number of days is much greater as well. The scatter plot of the production of conventional wells by age looks a little different. Here a summary of the data in those reports: 2,075 of these do not appear on the map due to missing location data.ĭEP collects data from the various operators on three types of production – gas, reported in Mcf and oil and condensate, both of which are reported in barrels. The original production report contained 192,335 records, which we have reduced to 61,213 by combining production figures for unconventional wells into a single annual total. Operators of unconventional wells are required to make similar reports, but on a monthly basis. The state’s conventional oil and gas wells report totals once per year for each applicable category. It’s also important to understand how the data are released by DEP, and what we’ve done to make understanding these reports a little bit easier. Also related to data quality, there are some wells on the report that lack location data, spud dates, or other information, which can obviously impact our ability to map or analyze these sites. Data errors happen, and some observers probably wouldn’t be shocked if they learned of an operator fudging the data. This dataset might show us, for example, that there are 213 wells that reported producing one thousand cubic feet or less in 2021, but can do little to vouch for the veracity of such claims. Next, it is important to point out that all production values are self-reported, meaning that DEP requires the operators to complete these records, but there is no in-field verification of any of the numbers. ![]() Total gas production in Pennsylvania over the course of a year is reported in this range. ![]() Some newer unconventional wells in Pennsylvania produce gas in this range over the course of a year. Such conversions are useful for dealing with larger amounts of gas. Operators report production to DEP in Mcf. First, it is necessary to discuss some terminology and abbreviations. Before we dive into the numbers, it is important to understand a few details about the data that we are looking at. ![]()
