... well control with a tapered drill-string: In the case study well, ballooning was identified and minimized which enabled to continue operations of performing a cleanout trip, liner trip, followed by managed pressure cementation with no issues. As an alternate ballooning can be ruled-out...

... Abstract Unconventional tight gas well encountered unexpected losses at target depth and simultaneously well control took place from water source in upper zone. Bleed off tests concluded it was kick rather than ballooning. Combining upper flow and lower loss zones resulted in downhole crossflow...

... Abstract Drilling S-shape wells across highly heterogenetic formations and at high inclination is particularly challenging due to increased risks, such as differential sticking, total losses and well control. This often leads to poor performance, stuck incidents, fishing operations...
