| Abstract: | Based on theoretical analysis in particular on several astable flows during under-balanced operations, this paper presents the governing equations and its boundary conditions and initial conditions, which lays the foundation of the study on the bottomhole flow pressure during the follow-up gas cut and the astable shut-in well. |

| Keywords: | under-balanced drilling two phase flow gas cut non-stabilization process equation data analysis |
