The Railroad Commission maintains maps showing historical, current, and proposed well locations


The Railroad Commission maintains legacy maps showing historical, current, and proposed well locations. The original hardcopy well maps are retained for researching older wells and validating historical information. In the past, these maps were updated using manual processes. These maps become worn due to multiple uses as well as saturated with handwritten data. Due to copyright provisions, public distribution was rarely available. Today, digital mapping is the norm and the legacy data is now part of the current geospatial dataset. RRC provides mapping products based upon customer requests.


The legacy data was derived using United States Geological Survey 7.5-minute quadrangle maps, which is approximately 7 by 8 miles in size, allowing for measurement based on latitude/longitude and a state plane coordinates system. The survey information was mapped through a two-step process. First, the lines were manually transferred from Texas General Land Office county survey maps onto USGS 7.5-minute quad maps using cultural features, such as roads and fences, for reference. The survey lines and related annotation were then digitized from the quad maps into the mapping system. Map data provided includes county and city boundaries, major roads and waterways, and original land surveys.


Each well symbol represents a single wellbore; one wellbore may correspond to several well completions. Various symbols are used to indicate the status of a wellbore based on the API (American Petroleum Institute) number and the well status. Well symbol consist of the two numbers. The first number is the most recent operator's well number. The second number is the last five digits of the standard API number assigned to the wellbore. Adding a three-digit county code before the five-digit number forms the complete API number. County codes are available at the following link view county codes.


Well information is updated daily in our database through a variety of sources: incoming applications to drill, completion reports, plugging reports, inspection reports and public inquiries. The most up-to-date products are available for purchase and are set to a specific scale:

Scale: 1" = 1,200' (standard product - map size 36” X 44”)
1" = 2,000' (some map features/text may not be legible – map size 24” X 28”)
Cost: $27.00 (quadrangle map 1” =1200’ & crowded areas at 1” =400’ or 1” =200’)
$15.00 (quadrangle map 1” =2000’)
$8.00 up to $42.00 (screen plot – price based on size of plotted map)
