Casing/cementing/zonal isolation
The authors describe a study in which leakage-rate modeling was performed to identify and evaluate the associated risks for designing a remedial action plan to safeguard a CO2 storage site.
The authors write that polymeric additives are effective in the design of complex systems to house important chemical reagents under challenging conditions.
This paper examines current practices and developing trends in well construction and describes an alternative cementless approach to the discipline.

The oilfield services company's Tubular Running Service was recognized for reducing costs, maximizing safety. -
The cementing services market size in the US is expected to drop 50% year-on-year from 2019. The significant drop in Permian Basin activity will account for 40% of the total market size reduction.
