Effect of Mud on Cement Sheath Integrity
Cement sheaths are among the most important well barrier elements and cement sheath integrity is thus important to maintain zonal isolation. Repeated pressure cycling in a well might lead to radial cracks and/or formation of microannuli in the cement sheaths. However, most experimental tests and mod...
Effect of Rock on Cement Sheath Integrity: Shale vs. Sandstone
Numerical Modeling of Radial Fracturing of Cement Sheath Caused by Pressure Tests
Cement Plug Sealing Studies of Silica Cement Systems
A cement plug is widely applied for permanent abandonment phase to provide long-term zonal isolation against fluid flow. Maintaining cement plug integrity is a challenging task, and loss in cement sealing poses risks to the surrounding environment and surface safety. It is well-known that the cement...
CEMENT BOND STRENGTH MEASUREMENTS
Cement is an important component to ensure safe and economic sustainable operations of a well. To optimize the performance of cement in a well, and to achieve an adequate level of well integrity, experimental testing of cement under realistic and relevant conditions is vital. This paper reviews thre...

Plug & abandonment of offshore wells: Ensuring long-term well integrity and cost-efficiency
There is an upcoming "P&A wave" of wells that need to be permanently plugged and abandoned, especially in mature, offshore areas such as the North Sea and Gulf of Mexico. It is important to ensure that plugged wells do not leak after abandonment, as there could be several potential lea...
