gas volume shrinkage due to liquids extraction

Post by vijaysin2000 »

Dears,
I am working on a gas exploration prospect, about 120bcf (recoverable) CGR of about 100, and pressures in the range of 3500 psi.

For the sake of sales gas calculations what sort of gas volume shrinkage due to liquids extraction should I assume.
Is there a thumb rule to this.
Can anyone help please?
No PVT available!

Regards

For nearest analog reservoir not very similar .
CGR>180.
That is why I do not want to use these figures.
Other than tests is there a formula to calculate?

If it is exploration prospect and production test not yet carried out then how you come up with CGR no of 100?
Mostly for exploration prospect analogues are used since you don't have any gas composition (reservoir fluid composition). there are methods to calculate shrinkage factor from provided gas composition.
