... downhole losses to a minimum while maintaining superior anti-migration properties. Challenge 2 : Cement integrity under multi-cyclic steam stimulation Multi-cycle steam injection process will lead to the cement sheath bearing multiple cycles of thermal load. The success of a single thermal load...

... Abstract The Gulf of Mexico (GOM) is home to thousands of deep water wells in a variety of status such as production, temporary or permanently abandoned. Regardless of the status of the well, the condition and integrity of the cement sheath behind casing is critical for the safety, performance...

... and low Young's modulus it can withstand cement sheath stresses well operations. For formation where hydrocarbons are not present to trigger the self-healing mechanism, the durable cement system is the solution to use. It has suitable components to optimize its mechanical properties to withstand pressure...

...OTC-26367-MS Self-Plugging Technology of Microcrack with Water in Cement Sheath Yuhuan Bu, and Huajie Liu, China University of Petroleum Copyright 2016, Offshore Technology Conference This paper was prepared for presentation at the Offshore Technology Conference Asia held in Kuala Lumpur, Malaysia...

... Annular pressure build up (APB) is caused by thermal expansion of wellbore fluid enclosed in an annulus experiencing cyclic thermal loads due to production and injection. This may lead to significant damage to the cement sheath causing zonal isolation issues and may also cause casing collapse...

... In Oman, certain fields contain heavy oil and recovery of this oil is done through steam injection, which leads to rapid heat-up of the cemented annulus to very high temperatures. Throughout the lifecycle of steam injection wells, stresses in the cement sheath induced by rapid temperature...
