What is the stress regime the site located? Micro HF -- pumped volume is tens or hundreds of bbls?

During flowback, is the surface pressure all the way back to 0 psi?

Q: Slide 9: Considering that the entire lateral has the same orientation, HF tortuosity initiated from the first and second stages may be almost identical. But, why did you assign higher ISIP in the second HF to larger tortuosity? How about the role of residual stress shadowing effect of the first HF stage?
Pierre-François Roux

How was temperature measured - point sensor, or distributed?
Hamed Soroush
56:43
What is your benchmark for comparing the results and evaluating which method yield more realistic stress estimates?
E Siebrits

To add to Mahdi's question, what did wellbore logs show in terms of properties variation along the MD between the locations of the 3 stages?

Pengju, your temperature convection model assumes that the fluid velocity is constant across the fracture width, but it is not. The fluid velocity is higher in the middle of the fracture and becomes zero at the fracture faces. Therefore, the heat transfer should be different. Can you please comment on the assumptions and applicability of the model that you use?

What is your estimate of Pp in zones tested prior to injection?
Nicolas Espinoza

Would you please comment on how SHmax was determined at the FORGE site?
Victor Soriano

How much error should I expect we I apply closure pressure estimation using flow back technique in tight sands (k<1md) ???

Why aren’t the wells deviated in the Shmin direction so that the HF’s propagate perpendicular to the well path?
Chengho Lee
01:07:25
zone 1 and zone 2 are about 400 ft apart -- could zone 1 DFIT (micro HF) injection possibly alter the Shmin gradient? via subvertical natural fractures or HF as high as 400 ft?

John, thanks for this great webinar and addressing my question.
Sherilyn Williams-Stroud

Are you monitoring induced seismicity with a one-well vertical array?
Andy.Duncan
01:12:09
Do you anticipate obtaining post-frac images in the horizontal/inclined wells also?
Egor
01:12:43
Thanks, Pengju!
Victor Soriano
01:15:24
Thank you so much

Did you find a good choke size for flowback that worked for your particular lithology?
Hamed Soroush
01:17:16
Thanks John and Pengju for the excellent presentation. Is there any publication on summarizing the results of these stress measurement?
Mohamed Soliman
01:17:42
great presentation. Thanks.

Was any logs run in the high temperature well - so stress, mechanical properties profiling done?
Pierre-François Roux
01:22:56
that's reall good stuff. Thank you both for this very interesting presentation!
Mahdi Haddad
01:23:16
Did you have the experience to miss fracture closure due to fast flowback?
Chengho Lee
01:23:48
Thanks John and Pungji for the talk! Gang, Andy - thanks for organizing the talk.
