Inside Drillinginfo’s Map Drawers # 8: Landtrac Leases and Units


Drillinginfo’s map drawers series has unpacked a number of cool concepts from plays and mapping technology. GIS analyst Ryan Nelson had these comments about this map of Leases and Units in Pecos County, TX.

Landtrac Leases and Landtrac Units work in harmony with one another in the Drillinginfo product suite in order to paint a picture of mineral rights coverage across the state of Texas.

Mineral Leases are signed on a relatively short term time period generally set to 3 years. If a lease has a well drilled on it which becomes an actively producing well, the lease moves to a state called Held by Production. At the end of the 3 year term when the lease would normally expire, those mineral rights instead remain held by the well as long as it remains producing at an economically viable rate. Landtrac Units are drawn based on permit filings for these wells in order to represent those pieces of land which may have an expired lease but are still held due to production. The Landtrac Lease product only covers mineral leases filed back to 2002; therefore any wells drilled on leased acreage prior to this time will be represented by Landtrac Unit coverage only. It is due to these factors that it becomes important to use Landtrac Leases and Landtrac Units collaboratively in order to best depict leased acreage in any given area of Texas.

Landtrac Leases and Units

Who asked for the map, and what did they ask for?

The GIS department created this map to highlight some of the products that they primarily work on.

Which DI Cartography Group made it?


Completion Date/Date of Production?

August 2014

Medium: Web/Print/Digital? (if web, WMS? WFS?)


Type or Style of Map (Projections?) (GCS? PCS?)

This Map is locally projected in NAD 1983 State Plane Zone 4203 to provide high accuracy in a small area. (NAD_1983_StatePlane_Texas_Central_FIPS_4203_Feet)

Sources of Data and How Processed?

Drillinginfo’s Landtrac Leases, Landtrac Units and Well data.

Choice of Scale/Direction and why?

The scale of the map is about 1:115,000. This scale was chosen to show an area that highlights the contrast between Landtrac Leases and Units in relation to active wells.

Choice of Color Palette and Font(s) and why? Transparencies?

The colors are intended to highlight the contrast of Landtrac Leases and Landtrac Units in relation to the locations of active wells. They are transparent in order to see the combination of the entities which overlap. A gray background was used rather than an aerial in order to remove clutter from irrelevant information.

Why we love it?

This map really highlights the role that Landtrac Leases and Landtrac Units play with one another in order to give the best overview of mineral leasing activity in an area.
