Numerical Modelling and Sensitivity Analysis of Gas Kick Migration and Unloading of Riser
de Sousa Gomes, Dalila; Bjørkevoll, Knut Steinar; Fjelde, Kjell Kåre; Frøyen, Johnny (Chapter, 2019)In deepwater wells there is a risk of gas entering the riser. This can be caused by gas being trapped by the BOP after a well kill operation, or it can be that the BOP was not closed quickly enough upon kick detection. ... -
Pressure Build-Up in Closed Wells During Kick Migration and Fluid Compressibility Effects
Agonafir, Mesfin Belayneh; Petersen, Johnny; Fjelde, Kjell Kåre (Chapter, 2022)If a kick is migrating in a closed well, this will lead to pressures building up in the well. It has earlier been shown that for Non-Newtonian fluids, suspension effects will make it impossible to deduce a unique gas ... -
Use of a transient model for studying kick migration velocities and build-up pressures in a closed well
Hang Ngoc Tat, Thea; Gomes, Dalila; Fjelde, Kjell Kåre (Chapter, 2021)The objective of the paper is to show that using pressure build-up curves for estimating kick migration velocities can be unreliable. This will be demonstrated by using a transient flow model where different flow patterns ...
