Translation for the uninitiated please? Is this an academic discussion are are real concerns being raised here?

OT - My Joy Knows No End: John and all - in addition to the ELH O&G excitement one of my side bets on PQUE is coming in big. siliconinvestor.com PQUE has shown life much like PYR. When we get the Canadains to show the equivalent trading life - life will be even better.

Good afternoon John. <<This is where I run into problems. As you said, the water should have been there immediately if it was all dense phase commigling like a bunch of ping-pong balls. It does, however, possibly indicate deep fractures that may be reaching way down to pull up water. It also lends a little credence to my Hysim model which says that water could exist as a liquid at these conditions (or aweful close to a liquid - heck what does dense phase look like any way?).>> I guess your Hysim model is telling us that any free water phase has to exist in a superheated liquid state given that Tc =705 and Tres ~350 deg. F.. The dense supercritical hydrocarbon phase will, because of gravity segregation, overlie such water. But, the hydrocarbon phase should also be saturated with water vapour (maybe ~40 bbls/MM ???? at ELH P&T). From day one, when the wells are produced the water vapour should be knocked out in the surface separation\processing facilities and the water cut should be ~40???bbls/MM. If excess drawdown is imposed on the producing wellbores, I believe there is a risk that "deep seated" free water could be pulled up fractured slip\bedding planes which plunge nearly vertically just a few hundred feet west of the wellbore. But, I have a great deal of trouble buying into the concept that free water was coned (by Bellevue#1), from considerable depth, via wellbore intersected fractures that are nearly vertical. (Such fractures would have resulted in hydraulic equilibrium with underlying reservoir "compartments" yet the various reservoirs supposedly exist at different reservoir pressures.). Comments ?? <<I was using the producing bottom hole pressure (14,500 psig @ 350 F) in my model.>> My Z calcs were for assumed initial reservoir conditions of 15,200\330 and 17,640\365 ... so we compare very favorably, IMO. <<This well has exactly the same water yield as it did on day one. I think the two phases are completely mixed but clearly insoluble.>> Excellent !!!! Sounds like you'll probably get ultimate gas recovery consistent with a volumetric depletion, say 85+%. Is that consistent with your expectations ?? Assuming you meant "day one" literally, your well clearly shows a very different behaviour than did Bellevue #1 and BKP#1. It is, however, the type of behaviour that I anticipate for BKP#2 ... that is an initial water cut in the range of 40 bbls/MM. (Notwithstanding that I think the "flow capacity" will be much greater, I hope BKP do not produce at greater than 20-30 MM/d, excepting of course one short duration isochronal test rate <gg>). John, you have previously indicated that you felt the tubing would limit the gas to 20 MM/d. Do you expect the JV to produce at that rate, or something lower ?? What water cut do you expect ?? <<IMOHO the 3-1/2" tubing is a practical choice for rig work. It may also be necessary to keep the production and drawdown at a certain level to keep the water at bay.>> Yep, looks like a KISS. Undoubtedly there'll be many refinements by time "someone" completes the 40th well in ELH !!! Have a good one. Later, grayhairs
