Energy sustainability is the main motive behind the evolution of the concept of well integrity
in the oil and gas industry. The concept of well integrity adopts technical, operational …

Our objective is to present selected rheological and mechanical properties of rock-based
geopolymers contaminated with different concentrations of drilling fluids. The possible flash …

In this experimental study, two different cementitious materials, including (i) a class of
expansive cement currently used for plug and abandonment (P&A) operations and (ii) a non …

A fundamental understanding of the mechanical properties of zonal isolation materials is
important for predicting well integrity during well operation conditions. Conventionally, the …

A cement sheath, placed between the casing and the formation, is an important barrier that
establishes a hydraulic seal and provides zonal isolation, preventing fluid communication in …

Portland cement is commonly used in everything from general construction to fluid barriers
in environmental and petroleum structures. Wellbore integrity finite element models have …

Generally, the expansion of cementitious materials has been regarded as a promising
avenue for better sealability. The sealability performance of an expanding geopolymer is …

Geopolymers have emerged as a promising alternative to Portland cement for oil and gas
wells. Achieving effective zonal isolation by use of geopolymers may require controlling their …

Sealability of barrier material is required for successful plug and abandonment operations.
The emergence of geopolymer as a green alternative to ordinary Portland cement presents …

Rock-fluid interactions in shale formations are one of the main sources of wellbore instability
issues and inadequate stimulation performance. For better planning of fracturing operations …
