Uniaxial compressive strength of geopolymer cement for oil well cement [PDF]
Journal of Petroleum Exploration and Production Technology, 2019 Ensuring oil-well-integrity is one of the challenging tasks when cementing is designed. It has been well established that cement tends to degrade when exposed to a corrosive environment and at elevated temperatures. This paper presents the results of the

Effect of Hole on Oil Well Cement and Failure Mechanism: Application for Oil and Gas Wells. [PDF]
ACS Omega, 2022 Cementing is an important operation in the drilling process. During the cementing process, mud cake, fracturing, perforation, and so on will cause holes in the cement sheath. Thereby, the size effect will reduce the cement strength, which will seriously affect the cementing quality. Several hole types were drilled to study the mechanical properties and
