Assessment of zonal isolation risk to changes in design parameters [PDF]
, 2017 The Well Containment Screening Tool (WCST) focuses on well integrity evaluation after well control incident. The WCST favors a greater wall thickness and, hence, a narrower cementing annulus, potentially increasing the risk of cement loss.

Application of cellulose-based polymers in oil well cementing
Journal of Petroleum Exploration and Production Technology, 2019 Cellulose-based polymers have been successfully used in many areas of petroleum engineering especially in enhanced oil recovery drilling fluid, fracturing and cementing. This paper presents the application of cellulose-based polymer in oil well cementing.

Oriented calcite concretions in Upper Miocene carbonate rocks of Menorca, Spain : evidence for fluid flow through a heterogeneous porous system [PDF]
, 2004 Elongate calcite concretions in Upper Miocene dolomitic, shallow-marine grainstones and packstones of Menorca document fluid flow through heterogeneous systems. These post-dolomitization concretions are thought to have grown with elongation axes parallel

Comparison between three glass fiber post cementation techniques [PDF]
, 2017 The aim of this experimental study was to compare the traditional cement systems with those of the latest generation, to assess if indeed these could represent of viable substitutes in the cementation of indirect restorations, and in the specific case of

Calculation of Cementing ECD for Well Annuli with Narrow or Varied Radial Sizes
Geofluids, 2023 In this present work, cement slurry flowing in well annuli with narrow or varied radial sizes is investigated, whose purpose is to precisely calculate the equivalent circulating density (ECD) during well cementing in the petroleum industry.
