Thanks again for a detailed reply.
Have learned a lot from yor two notes on drilling technoligy Etc.
Would be good to see more of this tech.on the BB.
Much obliged.

ronok,
"Can I just condense other questions. Will the recent advances in MWD / LWD eqipment improve Hurs chances of finding good fractures [hopefuully oil filled ] ?"
I'm not sure enough to give a yes / no reply to that.
I feel that the major benefit of the newest technologies will have its major benefit in identifying potential water zones in later wells. And this is not to say that absolutely the best equipment will have been used on the two existing wells.
Fractures (and thus optimal drilling locations) are initially based on seismic data. Seismic doesn't tell you what those fractures contain, though.
The company will have gone over existing LWD logs obtained while drilling (especially 7z) to see if there are sone sort of 'fingerprints' coinciding with this now empirially-proved perched water. Information possibly not exactly 'overlooked' when 7z was beng drilled, but just not recognised. So if / when well 8 is drilled, they'll know if there's possibly a zone which needs to be 'isolated'. And such 'isolation' will almost certainly be part of the drilling operation, not later, when the well is completed.
adoubleuk,
Thanks for that very full reply.
Sure that will interest a lot of LTH s.
Can I just condense other questions.

"Could these radical improvements result in a Control Room being established in the rig with drilling being controlled by information being fed up through the drill string ?.
Would imagine drilling times would be extended but the potential to get better information could be transformational to the end results. Daylight would not be an issue so the Control Room could operate 24/7... Would posters with experience and connections in the O & G industry be willing to investigate and develop further?"
This is essentially what exists already. With a 'nuance', however.
The MWD / LWD 'shack' is where downhole data is number-crunched by their computers. Certainly their is an MDW readout screen at the driller's post at the rigfloor,, though rarely LWD, because the data observed on the screen requires expert interpretation by the LWD engineer. There is usually an MWD readout in the Company Man's office, as well. Also (both rigfloor and Co-Man's office) there is another screen showing data from the 'Mud-Logger's 'shack'.
Usually these days, MWD and LWD data is also being fed back to town, and being watched by another engineer.
The onsite Geologist will normally be bouncing around between these various places on the rig, and usually with readouts in his own office. And everyone is in communication with each other.
However, there's just one thing. It's very rare to find a 'fully integrated rig' with everything all lumped together. Because actual control inputs for steering, for instance, are made by the Driller on the rigfloor. Sure there are certain 'autopilot functions', but they are just like an aeroplane's autopilot: you don't want it to steer you straight into a thunderstorm ! The thing being, the rig belongs to the Drilling Contractor, and is operated by their personel. The other 'units' (and personel) are 'third-party'. Hurricane for instance uses Schlumberger. The next oOperator may want Halliburton. So off comes the 'Blue Army's' stuff and on goes 'Big Red'.
Despite huge advances in the equipment, the entire process remains very much dependent on human decisions, sometimes made quickly, in the field, by responsible people.

A few weeks ago a poster ‘SCURR’ gave a pretty positive note on Hur and was good enough to expand on that in another note again for me.
He was aiming at those who do not work in the Oil & Gas industry in the content of his note. [ I would be one of these ]
When I read up on both notes and worked out what the abbreviations meant I was very impressed by the implications of the content. I would think interesting for many share holders.
One of his main points is that the MWD [measurement-while-drilling] technology has improved significantly very recently due to developments in the resistivity sensors placed in the bottom hole assembly of the drill string.
This improvement gives much greater geosteering capability and optimal well placement. The result is a visibility of up to 200 feet either side of the well bore as against around 25 feet previously. These tools will allow a more detailed map of the fractures along with steering decisions to be made as drilling is underway.
Could these radical improvements result in a Control Room being established in the rig with drilling being controlled by information being fed up through the drill string ?.
Would imagine drilling times would be extended but the potential to get better information could be transformational to the end results. Daylight would not be an issue so the Control Room could operate 24/7.
I have stuck my head over the parapet here not to be shot at but to stimulate interest in what I see as an area where Hur’s prospects of discovering oil, obtaining better drilling results, and data gathering could be greatly improved.
Would posters with experience and connections in the O & G industry be willing to investigate and develop further?
I do remember Dr. Trice saying at a Capital Markets Day that seismic do not detail fractures but showed the joints. He also mentioned that there was equipment being developed which could be able to show the fractures. Wonder if this is what he had in mind.
Would an experienced shareholder be willing to ask a question on this subject at the electronic AGM?
