Repectfully, you should not consider my comments about GOR across two separate geological basins criticism of your work. I simply think it is not yet relevant in the big scheme of things.

We did discuss using GOR across heavily saturated counties, I encouraged that, and you did. I think it is important.

GOR is well completion sensitive; more new wells lowers GOR temporarily and when fewer wells are drilled GOR increases again. Initial GOR is therefore important. I think in Tier 3/4 counties like Glasscock that is why the wild GOR swings. I do NOT believe few minor, secondary benches other than the big 3 in the Midland Basin have anything to do with county wide GOR.

I would like to determine if GOR is lateral length sensitive. I believe it is. Ultimately, of course, GOR is depletion sensitive and determining the bubble threashold and when associated gas declines afterward is the key to idenfifying depletion.

I am not a numbers guy, nor a chart guy. I'm an old oil man who undertands depletion, well economics, unbias data and relies on instincts. Permian HZ tight oil has plateaued already, IMO, and only super long laterals and big IP180's keep people from seeing that. There is little room left for those sorts of laterals and when that slows, decline will be signicant. Shale oil is losing money, big time, below $65. Ryan Lance with COP says the Permian plateau will last for decades. I don't buy that.

We will both agree likely that without Lea County, pundits would already be voicing concerns over Permian decline. EOG is Lea County's biggest operator. Lea County is about ready to start stumbling down the mountain:

EOG has drilled more wells in that blop of contiguous green acreage than Pioneer in almost all of Midland County. More benches in this country, and better wells than Midland, for sure, but those days are over. EOG is maxed out in this county; its doing nothing but filling in the blanks and looking, desperately, for other places to drill HZ wells anywhere it can in America. Its even back on my sorry country looking again. Its Lea block appears to have bubbled out and now gas, and oil, are going south, or oil is anyway. I know for a fact it has big well communication issues out yonder.

Also, look at the percentage of gas to oil in the production stream. You can't stop increasing gas, or arrest, even slow down the decline of this much developed acreage by drilling more pressure depleted wells...you'll just make more gas. A lot of its Wolfcamp wells are already drilled on <600 foot spacing in Phantom Field.

Here is a wad of Bone Springs EOG wells right across the State line in Sandbar Field. Its done the same thing in New Mexico. Carpet bombed it. EOG is the most successful of all pure shale oil players in the world but it come at a cost; it has to always be looking for new areas or though, it might be the only company that has made money in shale, it will also be the fasted to fold up its tent. It doesn't mess around with reservoir management, that sort of the dumb stuff.

Thank you. I will let you know.

Have now generated a lot of graphs for the top five Eagle Ford counties.

Again, I appreciate you sharing your work with us. Thank you.

I wish to go on record that it took me some time to convince myself that GOR across an entire country was relevant. I came to the conclusion it was in looking at Midland and Martin Counties, and Reeves, both densely populated with wells drilled close together. GOR can be bench specific and definitely spacing specific. Phanton (Wolfcamp) Field in the Delaware was drilled in some places on very close spacing, way too close of spacing.

I don't know that I see the relevance in an entire TRRC District, however, like 08. Ovi at POB likes to do that but I am not sure I agree. The District encompasses both sub basins, different they are than Mars and Venus.

When I find the time I want to understand better the relationship between longer laterals and GOR. My instincts say there is. I suspect super long laterals tend to get gassier, faster, from the inefficiency of frac'ing toe stages 3 miles away. If that is the case a lot of Delaware Basin wells would have an exponentially higher rate of rising GOR.

Above is a GOR chart for 16 of the top producers in Reeves County, in the Delaware, District o8. In the time frame of 2021 to 2024 GOR has gone thru the roof in this county (here gas has become the primary constituent of the production stream, not oil). This could have occurred within 3 years from depletion (most likely), from drilling fewer wells, or drilling longer laterals. Or all the above. At first even high GOR wells make lots of oil and only when they start to bubble out do they begin making more gas. If there are not as many new wells being drilled, GOR would tend to go up in a general area, like Reeves. I don't KNOW that is what is happening. Its probably depletion.

I don't see how anybody could look at Reeves County and say the Delaware Basin is the great hope for American tight oil. Its stuffed with wells, gassing out, liquids productivity is declining and there is water, water and water everywhere.
