Kick penetration is one of the most critical concerns for stripping operation because a kick height will change due to change of hole geometry. In this this article, we will describe about this situation.
This is will be happened when the string penetrates the kick.Height of influx will increase when the drillstring penetrates a kick; therefore, hydrostatic pressure decreases and casing pressure increases in order to compensate this situation.
If the casing is maintained constant while penetrating the kick, you will have high chance to take more influx because of underbalance situation (Figure 1). This article will teach you about how to determine pressure increment while penetrating into the kick, what to look for, etc. Continue reading
