Furthermore, the thermal-simulation tests conducted at research well Mallik 5L-38 were not only carried out to evaluate a potential production method or to prove the commercial viability of gas hydrates in Canada; but also to observe the dissociation of a gas hydrate interval at temperatures above the gas hydrate stability point, while maintaining constant pressure. The results of the thermal simulation were then used to calibrate numerical simulation models that give new insights into the kinetic and thermodynamic properties of gas hydrates.
Interval sounds like it might be referring to depth interval, or a range of depths, and stability sounds like it refers to a temperature below which there is stability and above which there is instability, at a given pressure. This link might help, though not an exact reference it's close enough to give you some ideas what's being talked about:

Now, what (the actual 'F#') does any of that mean???
- 'dissociation of a gas hydrate interval' ?? (interval in comparison to what??) (dissociation...interval??)
- 'gas hydrate stability point' ?? (stability with respect to what?) (blowing up the planet? being lost to the atmosphere...what?)
- 'calibrate numerical simulation models' ?? (simulation models of what??)
That refers to a marine environment, but even in underground alternating layers of sands and clays, there can be combinations of alternating layers of water and hydrocarbons.
Gas hydrate stability primarily depends upon temperature and pressure, however other variables such as gas composition and ionic impurities in water influence stability boundaries.
But those exceptions aside, the general rule I saw was after a certain depth, the deeper I measured temperature in a drilled hole, the hotter it was.
Where the problem comes in is when people throw out volumes of word vomit and intentionally say nothing at all. Then there's a problem, and that's what we have here on this subject.
Most of my measurements were made in the Gulf of Mexico at depths something like 1-2 miles deep. I also worked in Africa, on land and off the coast. The land drilling I measured tended to be shallower there, but offshore again was up to 2 miles or a bit more.

What depth was that? I don't expect this is a constant feature with the lumpyness of the Earth. As a rough mark how deep did you get?

Do you remember the posts by the dude who went by the name ".... "?
As I recall ,he admitted to canabis use, and had traumatization issues.
But basically his posts were "over the top" super techy mumbo jumbo jargon.
And he spewed it out in each and every post.
Why is this important to ATS? - Because, just about no matter where you look, there is clearly an attempt to make this whole subject just about as unintelligible as humanly possible. Why??? What is being cloaked? Just that alone should be enough to qualify as fodder for here on ATS, but there's more.

About the only thing I remember about chemical equations is:
PV = nrT
That is pressure*volume = temperature (without increasing the number of gas molecules in a given volume. Forgot what’r’ is for but it does not vary either.
So the ocean is cold, salty, and under pressure so it is colder than freezing at the floor. But the floor itself varies as does the temperature of the ocean currents. So sometimes the hydrocarbons “out gas” from the ocean floor. Some think that is the explanation for the Bermuda Triangle and all the vehicles sinking into the ocean.
You keep things in technical speak so, literally, the Natives don’t understand what you are talking about!
Grandpa White Man needs his energy and it don’t do him any good if he has to share wealth with First Nations types.
Sounds like you have a feasibility study about how much area is needed for an operation to be profitable.
But hey, wadda I know being in Alaska and all…
