>Why do you think XOM avoids reentering M-4 and M-6 to test the Szolnok in these locations? It would seem to be much more economical to test existing wells to locate "sweet spots" and build cross sections than to drill new wells. I understand they are FO's wells, but surely FO wants them tested and would make a deal to do so.
I think they need to find sweet spots before they spend lots of money doing well testing. The sweet spots could be be in a completely different area. Perhaps Exxon does not think the M4 and M6 are worth testing.
>Who do you think made the "final" decision on the location of the F-1?
The F1 location was determined prior to the JV agreement.
>Why do you think the high resolution seismic does not see the fracture systems?
I don't think you got the point of my previous message. I think the seismic did show the fracture system, and that's why they drilled where they did. In other words "WOW, look at all those fractures, lets drill a well there!"
>The source of the "fresh water" must be way up. Fractures would have to run through the horizontal stratifications in the Szolnok (I would think !)
Don't forget the Mako Trough is in the Pannonian Basin. An area famous for it's geothermal energy! The Bekes basin is right next door to the Mako Trough:
----------
The Nagyszénás area belongs to the southern belt of the
Békés Basin i.e. to the Battonya-Pusztaföldvár Mesozoic
Trough. The first exploratory wildcat oil well was completed
in 1954 at a depth of 3009m. During 1978-1988 six more
exploratory wells were drilled in the area with final depths of
2800-4200m. These wells confirmed the existence of
medium-high enthalpy overpressured geothermal resources
below a depth of 3000m. The steam blow-out of
Fábiánsebestyén 4 well and the flow test of well Nagyszénás
3 (Nsz3) confirmed that geothermal overpressured resources
occur in fractured Mesozoic formations in the area and may
be suitable for power generation exist.
Overpressuring in basement rocks, most of which are
fractured, may be caused by:
(i) aquathermal heating and
(ii) thermally generated carbon dioxide in the basement rocks
simultaneously with downward migration of fluids from
overpressured Miocene and lower Pannonian basal marl and
argillaceous marl.
