In some regards, the Eagle Ford is the most mature tight oil play in the world. The play is so densely drilled that each new well is closer to its neighbors than ever before. At the same time, average well productivity is falling after five years of strong growth. We can use the Eagle Ford to draw insights into the later tranches of infill well inventory. Our analysis focuses on the activity center known as the condensate window (Karnes Trough, Edwards Condensate, Hawkville Condensate, and Maverick Condensate sub-plays). We found that infill wells perform significantly worse than the first well within a section. Additionally, almost all new wells in the most developed parts of the play are infill.
