bigoilfields.com? Really? parker, sounds like big time spin to me. I have a friend who manages Stewart Title's corporate ranch in Pearsalll, TX. where this play is located. I sent him information when the first announcement was made last year. Probably nine or ten months or so ago. It was called the Maverick Shale back then by TXCO. Then Petrohawk made basically the same announcement a month later and called it the Eagle Ford shale. It was about that time that it was becoming obvious that there were quite a few North American shale plays. Good news that still doesn't seem to resonate in Washington. I find the bolded text to be an incredible assumption. Sounds like something a PR firm would put out. Not a legit E&P company. It appears to be an effort to get some publicity for the Play and some interest from investors and/or lenders for the operators.

I'm just trying to find out where the OIL play is at.

The experts say that it isn't deeper than the HS.

There has been a lot of talk about OIL of late. With as hot as the shale is who even needs another topic, but I keep hearing it come up.

My inquisitive mind just wants to try to guess where?

I just found this while searching.

Of all the "Shale Plays", Haynesville is the deepest. Many are considerably shallower. And likely to produce more liquids. Whether that's oil or gas associated condensate (wet gas vs dry gas) is above my pay grade. But it is a topic of some interest. Condensate has value but we haven't discussed it much as it is not a factor in the HS. The most valuable of the condensate liquids are butane and propane I believe.

Skip, propane & butane are actually part of the natural gas liquids and different from condensate.

Parker, if the Eagle Ford Shale was in NW Louisiana it would be only about 2000 ft deep. The Eagle Ford Shale in South Texas is a natural gas play with some some wells generating high condensate yields and rich gas.

Condensate carries the same value as oil and is utilized for the same purpose.

Rich gas (high gross heating value) can be processed for recovery of natural gas liquids (NGLs) such as ethane, propane & butane.

Check Petrohawk, Anadarko & St Mary Land websites for additional detail regarding the Eagle Ford Shale.

Skip,

The CV produces a decent amount of condensate.

Most people that I've talked to use the term condensate and oil interchangably.

I assume if there is any big oil discovery it will be condensate. CV or deep CV would be my best guess. I'm just guessing though.

parker. You have exceeded my level of knowledge for this topic. Alas I am only a HS devotee. But I find interest in many facets of the industry and appreciate the truly knowledgeable members who can answer our questions. Try this question, if the Bossier shale is the source rock for the CV intervals, do gaseous hydrocarbons convert to liquid form as they migrate upward in the stratigraphic column? I think condensate is appropriate only for what converts from gas to liquid at the surface (wellhead).

Skip, just keep in mind the source rocks (ie Bossier/Haynesville Shale) were not always at the depth they are today.

By the way, oil can be cracked into natural gas but not the other way around, at least not naturally in the ground. Just trying to avoid the Gas-To-Liquids (GTL) plant process.

I know in Lincoln Parish the LCV wells being drilled recently are making basically no condensate. The Upper CV wells make some in some ares. The Hosston (in this area) generally makes much more condensate.
The Haynesville Sand in Claiborne Parish usually makes a lot of condensate and is very rich gas. And the rich gas makes the owners more money from selling the plant products. And I think I have seen this trent on the northern limits of the recent Haynesville Shale drilling. I may be wrong, but this leads me to believe that those ares are the transitional areas, from sahle to sand. In the Haynesville LA area, the Haynesville Sand is referred to as a "shaley sand".

Parker, if the hydrocarbon is liquid in the reservoir then it is "oil". If the hydrocarbon condenses from the gas during the flow between the reservoir and the production separator then it is "condensate". See Electro's response above.

I won't even broach the subject of "retrograde condensate" reservoirs (which are rare).

Les, Electro, anyone - Would that gas condensate be a process similar to what occurs above ground when water heats & evaporates to become gas, then condenses as it cools in the upper atmosphere? With the exception that the ng didn't start out as a liquid like the water does.

thanks for clarifying - :0)
