Generally, the expansion of cementitious materials has been regarded as a promising avenue for better sealability. The sealability performance of an expanding geopolymer is compared to an expansive commercial cement in terms of the shear bond strengt

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 an option for well abandonment in a more environmentally friendly mann

A unique data set has been constructed based on the study of class G cement recovered from an oil well on the Norwegian continental shelf. The cement was placed between two casing sections and submitted to downhole conditions for 33 years. The aim of

An important pressure control issue during live well work is the expulsion force acting on the drillpipe. Wellhead pressure multiplied by drillpipe sealing area in the blowout preventor must be overcome before entering the well. The highest snubbing

Drilling and well construction operations involve fluid flow in the annular space between the drill string and casing or formation, or between casing and formation in the case of primary cementing operations. Knowledge of annular flow conditions is i

The ANSI/API Technical Report 5C3 was updated with addendum Annex M in October 2015 (informative). This is a significant step forward, since the effect of internal pressure on collapse is now calculated on the basis of Lubinski (1975) theory instead

This paper presents simple models to describe casing loading and wellhead movement during both the installation (mechanical) phase as well as the production (thermal) phase. Input parameters include hook load during installation and temperature chang

One consequence of the evolution of long and deep wells is that the design margins become increasingly smaller. Casing and tubing are pushed towards their yield strengths to meet the requirements of hot and highly stressed conditions. Also, the pipe

Expressions for calculating the stationary state distribution of radicals in compartmentalized systems with a constant number of reaction loci containing an oil-soluble initiator are given. Besides pairwise formation of radicals in the particles, des

Summary This paper describes a multistep pseudofunction-generation process designed to incorporate several scales of heterogeneities into one set of final pseudofunctions to be used in large gridblocks for field simulations. A detailed description of
