Compare choke equation between Schlumberger and Texas A & I Models.
These tools are useful when you want to estimate gas rate by increasing choke size during a welltest program. Suppose you want to test your gas well using separator test. You want to produce your well up to 100 MMscf/d.
Unfortunately, your separator test is limited to produce gas up to 30 MMscf/d. Using these tools you can predict your gas rate by changing the choke size. Gas rate can be calculated using choke equation from Schlumberger or Texas A & I models.
