would you, or anyone, perhaps interpret the ann. for me, in particular, re. the Upper Wilcox sand :
"well flowed back, recovering a portion of the load water with a light blow of gas"
Is this all good?
I think TEX might have provided a word or two of plain English explanation; not doing so is suggestive of obfuscation IMHO. They must think we are all experts!!
