Very first horizontal marcellus well?

I'm sure someone here knows when it was drilled and turned on? Is it still producing? Any guess how many cubic ft it has produced? Is it the only well on that particular pad? What is the name of it?  Lots of questions huh? :)

Renz Unit #1, Range Resources in 2004.  Three more laterals were drilled from the pad.  Located in Mt. Pleasant, PA.  Not sure if it's still producing.

It's still producing.  Last DEP report showed 8,749 Mcf's during 184 days of production, which averages out to be 47.5 Mcf/d.  You might note that it does not show to be a horizontal well however.

So evidently this well is not a horizontal? If it is, do you know how long the lateral is? I am asking  specifically for info about the first horizontal marcellus well. Just curious about how this well depleted... I know the newer wells are suppose to be better performers.

That is correct, not a horizontal as I noted previously.  It might have been the first Marcellus well drilled, but doesn't appear to fit into the horizontal category.  You would have to pull the permit to see what the projected lateral length was for any horizontal well.

Renz #1 is a vertical well.  Early on in the play, Range was only drilling vertical Marcellus wells.  Then Atlas (aka Chevron) chimed in and started to do vertical wells also.

so does anyone here know anything about the first horizontal well and how much it still produces or is it now a dry hole and plugged... just wondering about the claim that " these wells produce almost all their gas in the first two years" and what it could  be producing in 6 or 8 years.

Rick -

I don't have access to any Marcellus production history, but I do remember that wells producing from "dual porosity" reservoirs(combination of fractured or natually fractured rock and matrix rock) tend to have high decline rates early in their productive lives, and then the production rate declines much more slowly and single wells can produce for decades. This is commonly referred to as a "hockey stick" decline profile. Even vertical wells can exhibit dual porosity behavior, depending upon rock/reservoir type and regional sub-surface stress orientation. At current suppressed gas prices, the Renz Well #1 is producing enough to cover basic lease costs and taxes, but not much more.
