RE:RE:RE:RE:RE:RE:Chinook Prospect SizeYou expect ME to come across detailed maps ? Well OK, I'll try and I appreciate the confidence you have in me. LOL
This stuff fascinates me so I could keep at it all day but I'll try to restrain myself with only one more.
At Cascadura, if I have this right, they flow tested the well which was great and then they put down recorders to take various readings, pressure being an important one I believe, and those readings were then passed along to our reservoir engineers who used that data to determine the size of the field, approximately I guess.
What I can't figure out is how a gizmo dropped down 8,000 feet and that reads pressure can tell if a gas column extends out from the well bore, 1000 ' , or 2,000 ' or 10,000 '.
Unless that's not what the recorder does but I thought it played a part in that.
Can you explain briefly what a recorder does tell us and then I'll leave you alone for awhile.
Much appreciated.

Your welcome. I'd say given the 600' pay number, you're in the ballpark but as you noted area is the big unknown. They will get a better handle on that with prolonged flows and shut-ins.
Paul mentioned the sands will be tested in three intervals, perhaps meaning they are separate reservoirs with separate pressure regimes. This could complicate things in terms of aerial extent and calculating reserves. The 2 tests at Cascadura I believe showed the sands to be in pressure communication because the difference in pressure between the midpoints of each tested sand was that of a gas/condensate gradient... tougher to explain than it really is ...AND Paul said so. I believe Paul mentioned one of the intervals was the same as in the 7X well. If this extends back to the BW 7 well, then you're looking at the sand extending about 3000' to the north. (A mile square is 640 acres). Shell drilled the CO87 well to the south of Chinook in 1959 to 10,283 feet and mentioned testing gas from the "upper sand" (whatever that means). The problem is I don't have proper maps to measure the distance between the BW 7, 7X, Chinook and CO87. If you find any detailed maps with these wells and a scale we map be able to better guesstimate the extent of the gas. Let me know.
