dc.description.abstractThe Eagle Ford Shale in south Texas is one of the most prolific unconventional hydrocarbon plays in the world (Breyer, 2016). In 2015, natural gas and oil from this field hit peak production numbers at 5,539 MMcf (million cubic feet) and 1,118,648 Bbl (barrels) per day, respectively (Texas RRC, 2016). The aim of this study is to identify any geomechanical and geochemical properties that optimize fracture connectivity within the Boquillas Formation, the West Texas Eagle Ford Shale equivalent. Here, I present a geologic map completed at 1:6000 scale of the area in and around Heath Canyon as well as data taken from four outcrop stations within Heath Canyon. Mapping was completed to understand local deformation. Fracture spacing, frequency, and vertical persistence measurements were taken in the field as well as rock strength and hardness measurements. Energy-dispersive x-ray fluorescence (ED-XRF) was used to determine the bulk elemental composition of the material and semi-quantitatively assess chemical variations throughout the outcrop. Geochemical and geomechanical data from this study suggests that fracture frequency and length/height are affected by the clay and calcite content, and, by inference, the strength of the rock.--Abstract.en_US
