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?
