I understand on 3-D Seismic you see a "Bright Spot" for Nat Gas--- If this is true can you get a estimate about quantity that is in the formation or only just the Seismic will tell you simply  Nat Gas  is there. Can operator predict if well will be good gas well or not based on seismic ?

Thanks Jay--so seismic primary give you the formation information but if it does give off a hydrocarbon signal of bright spots can geologist get a prediction of amount of production a well may produce if drilled ?

Jay-- so in Shale formation like in the Haynesville or Bossier in La or East Texas   with 3-D then analysis can not predictable if well is drilled if would be good ROI  commercial or not--just will only show formations. Then have to drill it to find out if area good or not then that data can correlate with continuous off set wells if formation ID on seismic --- is this correct understanding of what 3-D benefit is to operator--- Bright Spot just says there is some hydrocarbons present but not to quality of rock or quantity that would be expected if drilled--- I know it is not that simple but is that it in a nut shell simple terms.

Jay's description of seismic use in shale reservoirs relating to "dips, faults and stratigraphic interruptions" explains why 3-D was utilized regularly in the Haynesville Basin after lease rights were acquired and drilling was underway.  And why seismic shoots which occurred post initial Haynesville drilling was often misinterpreted as being associated with something other than the H Shale.  The deep oil below the Haynesville being a good example.

Skip, Has any of the deep oil below the Haynesville you referenced been drilled?  

As far as I can tell, bshelby, there is no oil below the Haynesville Shale.  Considering the depth, that's hardly surprising. However there is a good chance there are liquids below the Haynesville Sand in far north LA.  The difference is depth and thermal maturity.

What about the different color pieces they put our. What does that mean ? What about Beauguard Parish ? Are y'all going to Dry Creek, la, which is in Beauguard Parish ?
Thank You ,

In Layman words, what are the different colors? If you have a lot on your property what goes this mean. We haven't heard from anyone in almost 2 yes ?
Thank You , J R C

Ms. Conner, I can not answer your question as to colors.  I suggest that you review past discussions on seismic in the  GHS archive.  I'll post a link below.  As to the 2 years that you haven't heard from the seismic company, I suggest you call them.

How do I do this? There are flags all over , who I get in touch with? She'll shot there in around 1986, they found oil, gas, & distelent. Thy said over a 100 yrs. can you help us, please.
Thank You, Jessye Conner

What do you want help with? The seizmic people always tell the same story about the lake of oil under the property. You need to take what they say with a grain of salt.

Click on the link above (in blue).  Then click on the discussions that sound relavent. 

Skip,

The colors I think she is referring to are the different colors of flagging that they use to set up the shot points and the receiver/data points. That's just a guess as to what she is asking.

So to explain a little: In a 3-D shoot there are shot points (that's one color ribbon) and receiver/data points (a different color ribbon). While each shot point is shot individually all of the receivers are turned on with each shot. Then this data is taken back to the computer center and the computer puts the data together and forms a 3-D image of the subsurface. This process takes a considerable amount of time. Actually, several months from start to finished data presentation. Its also interesting that the crews on the ground see absolutely nothing. Their is no raw data print out as there was in the old 2-D days. The crews are blind as to what they are recording.
