The future of smart fluids technologies and zonal isolation techniques does not lie in legacy and traditional approaches. The future is instead in the hands of the technology that can properly handle it and its evolution. To date, zonal isolation and fluids remain key objectives during well construction phase. Drilling hazards such as lost circulation or inflow events leads to not ideal casing design and cement placement success as well as contamination with native wellbore fluids. Introduced in this session is potential solutions to overcome lost circulation, advances in drilling fluids modeling and methods to compliment primary cementing.
