Mapping the History of Extractive Oil and Gas Industries in Lea County in Light of the Transition to Unconventional Methods

Introduction Motivation Methods Results Conclusions Future Work

Aerial imagery is from the National Agriculture Imagery Project (NAIP).

I downloaded the data from the USDA Natural Resources Conservation Service “Geospatial Data Gateway”

https://gdg.sc.egov.usda.gov/

There is a plethora of data you can request for free download here, based on an interactive location and product requests.

You can download data as a geodatabase or as shapefiles.

I downloaded the “digital orthophotoquad” in the 7.5 minute mosaic. Which came projected in UTM Zone 13.

Well data is from New Mexico Oil and Gas Conservation Division website

ftp://164.64.106.6/Public/OCD/OCD%20GIS%20Data/

These were comprehensive shapefiles using NAD 1983 GCS, but I only needed these attributes:

I used select by attribute to group wells on a variety factors. I used various combination of type, status, direction, year-spud, spud-date, effective, and plug-date.

I used ‘export data’ and ‘save as layer’ to turn the important selections into other shapefiles, and add them to the map.

Then I changed the symbology and configuration of the layers upon basemaps I had made in order to highlight and compare different things.
