The cement sheath, serving as the primary element of well barriers, plays a crucial role in
maintaining zonal isolation, protecting the casing from corrosion, and providing mechanical …

This review paper introduces a conceptual model to enhance the sustainability of cementing
operations in offshore wells. Traditional cementing practices, characterized by significant …

Thixotropic cement paste, which destroys the grid structure under shear action and rapidly
recovers its previous state after a standstill, is an effective method to solve cementing …

Enhanced grid reconstruction ability of oil well cement paste has been confirmed as a
promising solution to inhibit particle sedimentation caused by the uncontrolled rheological …

The development of oil and gas infrastructure requires the development of new fields or the
renewal of existing ones, which are mainly located in complex mining and geological …

Fluid migration behind casings is a well integrity problem that can result in sustained casing
pressure, undetected leaks to the environment, and potentially very difficult remediation …

Gas migration through fresh and hardened cement slurry is an ongoing problem in the oil
industry. In order to eliminate this unfavourable phenomenon, research is being conducted …

Commercial synthetic polymers are a professional approach to creating versatile new
materials with high-performance classes. This research focuses on controlling gas migration …

In this paper, we study the boundary-layer flow of a Herschel–Bulkley fluid due to a moving
plate; this problem has been experimentally investigated by others, where the fluid was …

A modified wellbore simulation chamber (MWSC) was used to simulate gas migration
through cemented annuli at early ages. A series of gas migration tests were performed on …
