Vitrinite reflectance data for the Permian Basin, west Texas 

and southeast New Mexico 

This report presents a compilation of vitrinite reflectance (Ro) data based on 

analyses of samples of drill cuttings collected from 74 boreholes spread throughout the 

Permian Basin of west Texas and southeast New Mexico (fig. 1). The resulting data 

consist of 3 to 24 individual Ro analyses representing progressively deeper stratigraphic 

units in each of the boreholes (table 1). The samples, Cambrian-Ordovician to 

Cretaceous in age, were collected at depths ranging from 200 ft to more than 22,100 ft. 

The Ro data were plotted on maps that depict three different maturation levels for 

organic matter in the sedimentary rocks of the Permian Basin (figs. 2-4). These maps 

show depths at the various borehole locations where the Ro values were calculated to be 

0.6 (fig. 2), 1.3 (fig. 3), and 2.0 (fig. 4) percent, which correspond, generally, to the onset 

of oil generation, the onset of oil cracking, and the limit of oil preservation, respectively. 

The four major geologic structural features within the Permian Basin–Midland 

Basin, Delaware Basin, Central Basin Platform, and Northwest Shelf (fig. 1) differ in 

overall depth, thermal history and tectonic style. In the western Delaware Basin, for 

example, higher maturation is observed at relatively shallow depths, resulting from uplift 

and eastward basin tilting that began in the Mississippian and ultimately exposed older, 

thermally mature rocks. Maturity was further enhanced in this basin by the emplacement 

of early and mid-Tertiary intrusives. Volcanic activity also appears to have been a 

controlling factor for maturation of organic matter in the southern part of the otherwise 

tectonically stable Northwest Shelf (Barker and Pawlewicz, 1987). Depths to the three 

different Ro values are greatest in the eastern Delaware Basin and southern Midland 

Basin. This appears to be a function of tectonic activity related to the Marathon-Ouachita 

orogeny, during the Late-Middle Pennsylvanian, whose affects were widespread across 
the Permian Basin. The Central Basin Platform has been a positive feature since the midto-late Paleozoic, during which time sedimentation occurred along its flanks. This nonsubsidence, along with the lack of supplemental heating (volcanism), implies lower 

maturation levels.

Table 1: List of boreholes in the Permian Basin, west Texas and southeast New Mexico, from 

which drill cuttings were collected for vitrinite reflectance analysis. Eighty-four boreholes are 

listed, and locations are plotted in figure 1. However, depths to the 0.6-, 1.3-, and 2.0-percent 

vitrinite reflectance levels were calculated for only 74 boreholes because for the other 10, shown 

as green dots in figure 1 and identified here with the notation “Location not listed in figures 2-4,” 

the stratigraphic intervals sampled were too limited for constructing meaningful regression 

curves to accurately determine depths. 

[Map ID, borehole number (fig. 1); Lease Name, oil and gas lease name and number; Operator, 

borehole name; Depth (1st column), sample depth in feet; %Ro (1st column), mean vitrinite 

reflectance value; Longitude and Latitude, indicates center point within a quarter-mile grid cell 

in which borehole is located (proprietary agreement with database provider prevents the listing 

of precise longitude and latitude); Elev., surface elevation at borehole location; %Ro (2nd 

column), the three vitrinite reflectance values for which depths were calculated and plotted in 

figures 2-4; Depth (2nd column), calculated depths corresponding to the three vitrinite reflectance 

values; Depth (3rd column), below sea-level elevations of the three vitrinite reflectance levels.]
