It allows to raise the accuracy of determining productivity coefficient of gas condensate wells, especially low-yield ones.
Advantages:
- Research of wells at the moment of stopping and in one of technological regimes measuring yield and bottom-hole pressure.
- Coefficient of filtration resistance "a" is determined by a formula.
From 1991 to 1996 it underwent tests at Vuktylsky, Zapadno-Soplessky, Pechora-Kozhvinsky, Yugidski deposits. Since 1996 it is introduced into research practice.
Patent # 2055179.
Specific Economical effect for one well was 7.450 roubles.
