Effects of confinement pressure on the mechanical behavior of an oil well cement paste
Lima, Victor Nogueira; Silva, Flavio de Andrade; Skadsem, Hans Joakim; Beltran Jimenez, Katherine; Sunde, Jonas Kristoffer (Peer reviewed; Journal article, 2021-11)Oil well cement paste is a key structural component in wells that should provide mechanical support to the casing and prevent uncontrolled flow of formation fluids along the wellbore and to the environment. Since the annular ... -
