Well Pressure and Initial Production

If the well pressure measured at say 10,000 pounds after fracing, can any conclusion be drawn just from that data about the possible production before the flow tests are run? I got this pressure information from one of the field personnel doing the fracing for a well in the Greenwood area.

Bud, not really since that is the formation pressure for the Haynesville Shale and is similar throughout the play. The pressure gradient for the Haynesville Shale is ~ 0.90 to 0.92 psi per foot of depth. You can use that value to estimate the formation pressure based on the Haynesville Shale depth in an area. Generally the Haynesville Shale is deeper as you go south so the pressure is higher in Sabine Parish than Caddo Parish.

Tuscaloosa Trend Sits On Top Of Poorest Neighbourhood For Decades - Yet No Royalties Ever Paid To The Community -- Why??

In researching the decades-old Tuscaloosa Trend and the immense wealth it has generated for many, I find it deeply troubling that this resource-rich formation runs directly beneath one of the poorest communities in North Baton Rouge—near Southern University, Louisiana—yet neither the university ( that I am aware of)  nor local residents appear to have received any compensation for the minerals extracted from their land.

This area has suffered immense environmental degradation…
