Casing/cementing/zonal isolation
This paper presents a comprehensive literature review of perforate, wash, and cement techniques that compares new methods with traditional ones and uses field cases and computational fluid dynamics to find the most cost- and time-effective practices without sacrificing safety.
Cementing and zonal isolation remains an important topic to operators and service providers alike. Additionally, an increase in the number of papers with both academic and field-driven content shows that there is no lack of initiative for operators to materially improve on existing methods and technology.
This paper highlights nontraditional methods to cure oil-based-mud losses in horizontal wells drilled in unconventional plays.

The authors seek to eliminate the need for pressure testing in the evaluation of annular creep barriers by qualifying the barrier using only cased-hole log measurements. -
In the October 2021 issue of JPT, incoming SPE President Kamel Ben-Naceur discussed the importance of collaboration in solving technical problems quickly and efficiently. Three of the papers selected in this section are from collaborations between multiple companies pooling their expertise and resources to develop solutions for complex problems that could not be addre…
