Developing large acreage positions of unconventional and conventional oil and gas resources
>1.) Anyone know which rig contractor Exxon/Mol are using?
On the Foldeak-1, MND Servisni (Czech Republic)
On the Mindszent-1, Rotary (subsidiary of Crosco). On the HOD-1, I don't know, probably Rotary since they took a rig down from the M1 and put up a rig at the H1 within a short period
>Any idea on which tools/services or service companies have the contract with Exxon/Mol TXM?
I don't know
>Whats the current status of the mindzent and hod-1 wells
As of Dec 31, M1 suspended, Hod-1 active, probably suspended by now.
>remember reading that down hole pressures and temperatures would be exessive (ie 20,000 psi+, 150 DegC+). Does anyone have a geologial prognosis or detailed report on the szolnok to confirm?
The pressure gradient is about 1 psi per foot, so the deepest part of the Szolnok should be around 14,000 psi. As for the pressures & temperatures of the Mako trough, this story tells it all:
"Two records were broken during this challenging well kill and suspension operation – the deepest packer ever set in Hungary at 5,198 m/17,054 ft and the highest temperature for cesium formate brine use. The previous temperature record stood at 216°C/420°F, set in January 2005, during an HPHT completion for Walter Oil & Gas in the US Gulf of Mexico. Now, since TXM chose 2.15 s.g./17.94 ppg cesium formate brine for its Mako-6 well, the record has been upped to 225°C/437°F."

>Is the szolnok sour too or is this the endrod and deeper sediments?
Yes, they had H2S in the S1 well.
>Anyone know details on the service/rig company TXM used on the first set of wells?
Haliburton, Schlumberger
>Well testing - Who did it? Why did it fail? Are they going to try and do it again? Are there published results anywhere?

Biggest problem was the H2S, especially on the Mako-6. They had to kill it, drilling fluid was down there for 5 weeks or so, then it got plugged (barite plug failure).
I doubt the edge wells will ever be tested again. The Mako-6 could be I suppose. There is also the Mako-7 deep well that hasn't been touched since it was drilled. According to the Exploration agreement, Exxon might use these for testing the Basal Conglomerate (near the bottom) "at a later date"
