Velocity Pull Down Confirmed in Press ReleaseFrom: CASPER, Wyo., Oct. 19 /PRNewswire-FirstCall/ -- Double Eagle Petroleum Co. (Nasdaq: DBLE) reported today:
"Table Top Unit #1 well at the Christmas Meadows Prospect, was at 4,666 feet."
"Previously, at approximately 3,700 feet we penetrated the North Flank Fault of the Uinta Mountains."
"We now appear to be drilling in the Paleozoic beds in the Hogsback Thrust Sheet of the Rocky Mountain Thrust Belt."
This is great news as all of the previous interval velocities assumed for the Pre-Cambrian interval above the North Flank Thrust was based on assumptions that these rocks were going to be hard and dense.
By correcting for a velocity pull-down, the structures within the hanging-wall and foot-wall of the Hogsback thrust should come in high to prognosis, and the structures may have more closure than previously anticipated.
The formation tops below the North Flank Fault, on the published cross section, will need to be corrected upward. In other words the Paleozoic rocks below the North Flank thrust would come in high to prognosis as I previously speculated. This has been confirmed today as Paleozoic rocks (not Jurassic rocks) were encountered directly below the North Flank Thrust Fault.
Again, it is possible to find oil and gas reservoirs at any time within a higher than anticipated structure and/or possible structure closure (anticline or dome) located below the North Flank thrust.
Correcting for an interval velocity pull-down should also have positive implications on the deep double plunging anticline (dome) projected below the deeper Hogsback thrust. In other words there could be more structure closure than previously anticipated.
