The Eagle Ford Shale

The Eagle Ford Shale is located in South Texas and covers multiple counties. Drilling activity in the Eagle Ford Shale escalated dramatically in 2010 and wells have proven to be promising in the oil, wet gas and dry gas windows, yielding large amounts of reserves. The Eagle Ford formation is located between the Austin Chalk and Buda formations, and is source rock for hydrocarbons found in the Austin Chalk. Composition of the Eagle Ford Shale includes a high percentage of calcite and silica making it brittle and easily fracable. Horizontal drilling techniques have helped revitalize the area which was previously discounted after the Austin Chalk boom. To date more than one hundred and fifty wells have been drilled targeting the Eagle Ford Shale formation.
