文摘
- •
We propose a procedure for complementary flowback and post-flowback data analysis.
- •
This procedure reduces the uncertainty in reservoir parameter estimates.
- •
The proposed procedure is applicable to transient two-phase pressure and rate data.
- •
Field application estimates the effective pore-volume and half-length of active fractures.
- •
Secondary fractures and desorption play key roles during post-flowback production.
