Well integrity/control
This paper examines the effects of cement voids and microannuli on the collapse resistance of pipe/cement/pipe systems with void angles ranging from 0º to 70º.
This paper describes the evolution of the operator’s initial PWC (perforate, wash, and cement) abandonment projects performed in deepwater Brazil.
The authors reach conclusions that the industry should define a standard testing method to improve swelling performance, including validation of repeatability, to complement existing guidelines.

The purpose of this work is to investigate typical fracture and collapse models with respect to accuracies in the input data. -
Deepwater cementing becomes increasingly challenging as drilling operations move to greater water depths and more-remote locations.
