Hi guys, Is there any data out there about stage fracing vs. non where in-fill is planned? Not sure if I am stating the question accurately : let me try again. Where there is only one well, stage frac'd vs. units with non-stage fracs but more than one well ... I guess this plays into the decline curve analyis aspect from a recovery aspect of 2 or more infill wells using unlined, single stage fracs vs. data about same situation using 9-12 stage fracs...... follow? The decline curve stuff is a really tough thing to get a grasp on.... Has Marathon done multiple wells/unit with single stage frac in Dunn cty? Have they done multiple well/unit with fracing? Are there data points out there from them? Rufus
