Ann: SGC: Initial Workovers Increase Gas Flows in Sacramento Ba, page-44

PP 10TCF is probably conservative, going by the posts your quoting, they never overstate anything there..

So out your ways, theres the NW shelf has had $25 billion thrown at it and holds 33TCF.

Rio Vista in california covers 120 square km and has only produced 3.7 TCF. so the 10TCF for Borba (although conservative at 3 times larger than Rio Vista) and probably way smaller in size ( i assume its not 360 square KM) , so going by the numbers, its one hell of a discovery by the operator.

how many acres is Borba again?

I wonder if they will use a BOP stack like this one, i image the pressures down hole will be astronomic going by the very conservative numbers your quoting.. ..
