Results of a reservoir level seismic surface depth tie to the available well control. The purple trench (upper left) is associated with near-surface velocity variations modeled using three-term tomography. The tightening of the well tie histogram (lower right) provides more confidence in the depth of the interpreted surface after advanced imaging.

(Left) Interpreted top Hunton horizon co-rendered with most-positive curvature attribute and displaying the horizontal wells drilled into the Hunton horizon and colored by fracture density. (Right) Most-positive curvature attribute co-rendered on the top Hunton horizon and colored by most-positive curvature strike direction. Yellow arrows on both images show areas where mostpositive curvature visually correlates to high fracture density along the wellbore.
