Hi Rick,
I guess if you're down to criticizing the spelling and the grammar of others on this thread, then you will not be offended if I point out a couple of "errors" in your own post. (I'll overlook your spelling and grammar errors though!)
It would be in the shape of a sphere, but gravity comes into the equation.
Ha Ha Ha. Ho Ho Ho. That's funny, Rick. Really, really funny !! Ha Ha Ha. Ho Ho Ho.
Oh by the way, how is a partial vacuum created in the reservoir? Were you not the one that would have us believe that this reservoir is at ~18,000 psi ?? Pressure gradients are of course established in the wellbore and in the reservoir, but a partial vacuum ?? Well, that's pretty darn funny, too!!
In spite of your description of the coning phenomenon <ggg>, I happen to believe that all of the produced water is coming from the Temblor formation, as a consequence of either "coning" or "channeling". I also suspect and believe that the casing\cement bond is irreparably damaged in the ELH #1 well, but because of the production behavior of the well, I do not believe that the produced water is coming from an uphole zone.
The well production behavior is quite consistent with water coning or channeling. After the rig debris was removed, the www.bakersfield.com video shows that the well was producing relatively dry gas. But then a few days later, the well began to make some steam. That behavior is perfectly consistent with the arrival, or breakthrough, of the tip of a water cone at the base of the openhole section of the well. As the water cone grew the amount of steam increased steadily. Finally, the water "flooded" the openhole section of the wellbore and the water cut increased enough to extinguish the flare.
While water production from an uphole zone via a casing leak can not be conclusively ruled out yet, that is much less probable given the well behavior. Very significant amounts of water should have been produced from day 1 if this was the source of the current water.
...we likely have a gas/condensate/oil/water situation. These fluids arrange themselves naturally in the rock in that order, gas being the least dense (lightest) and water the most dense (heaviest).
No condensate underlies the gas column of this reservoir. The condensate observed at surface formed during the production process, in the wellbore, as a function of the pressure and temperature reductions experienced by the gas as it flowed to surface. Condensate is often referred to as NGL (natural gas liquids) and is a blend of liquid pentane and heavier hydrocarbons (traces of ethane, propane and butane are also commonly present).
I have considerable difficulty believing that there is an oil leg in this reservoir, which must be at a temperature of something in the order of at least 325 degrees. I am not saying definitively that oil can not exist in this reservoir, but I would believe that to be a very low probability. And, if in fact all of the water being produced from ELH #1 is coming from the Temblor, then we already know that there can be NO oil leg in the Temblor. How ? Because if there were an oil leg, the oil would overlie the water and an "oil cone" would have developed in preference to a water cone. That has not been the case.
Now, what was it you were saying about not believing everything we read and "baffle with bullshit" ??
Later,
grayhairs
P.S.-- I also strongly disagree with your statement that coning, by definition can not take place in a fractured reservoir, but that is off topic so.... |
