Conventional (n=97,844), shown in orange pentagons.The well categories shown in this map are as follows: We’ve done that here as well, although we have modified the dataset by separating three different well statuses and one group of well types that we think are of interest to our users. Such differences serve a good reminder that available data and realities in the field are not always the same thing.įracTracker, along with DEP, typically separate conventional and unconventional wells when mapping them. We don’t know whether these wells are conventional or unconventional, for one example, or whether the well is for production or waste injection, for another. Despite having five percent more wells in that inventory than the one we used, it is much less comprehensive in terms of associated data fields. PASDA has another dataset of wells that has even more locations, 220,015 in total as of January 11, 2022. The foundation for this map is a data layer called “Oil and Gas Locations – Conventional Unconventional,” which is published by the Pennsylvania Department of Environmental Protection (DEP), and made available on the Pennsylvania Spatial Data Access, also known as PASDA. There are some additional adjustments that could be made if this seems to be a widespread issue. To that end, please let me know if you are having difficulty loading the maps. In fact, I’m a bit concerned that this density may still be too much data for some computer systems to efficiently handle. This allows for a visual representation of the industry’s extent, while significantly reducing load times – by not drawing dot, on top of dot, on top of dot – until the user zooms in to a scale of 1:500,000, which is about the size of a county.īut there is still good news for those who enjoy looking at maps with thousands of dots on it, as the screenshot of the border between Armstrong County and Indiana County demonstrates. ![]() ![]() Because these factors can vary tremendously from person to person, it still makes sense to do everything that we can to minimize the effect of loading datasets as enormous as the full inventory of Pennsylvania wells.įor that reason, we continue to use “generalized” layers, which are formed by creating a buffer zone point facilities that display when users are zoomed out. Serving data is only a portion of the bottleneck with map performance when using large datasets – as all of this has to be funneled through the end user’s computer system, internet connection, and browser software. ![]() Previously, putting over a quarter-million points on a map resulted in very sluggish map performance, but we are taking advantage of improved data delivery capabilities from ArcGIS Online, which we’ve been using for our online mapping system since 2012. The fundamental difference is that conventional and unconventional wells are shown on the same map, with plugged wells also included. Although we’ve made many different maps to show the spread of the oil and gas industry across the Commonwealth over the years, this one is set up a little differently from the others.
