... Modulus 1.2-1.4 MMpsi Damage Mechanism The well was diagnosed for potential damage mechanisms and high graded according to their likelihood of occurrence ( Table 2 ), from which it was concluded that fines migration due to sand failure was the main cause of skin, this is mainly due to the fact...

... This broad range alone invites the study of the interplay between framework mineralogy and damage mechanism. The literature is clearly directing the understanding that softening due to aqueous interaction is a major source of increased proppant embedment, that in turn leads to reduced hydraulic...

... infiltrations in and out of its pores at close proximity to the CS layer, which induces mechanical responses that impact the size of the fluid-filled pores. The following three assumptions are honored in our model: The wellbore, the cemented-casing string, and the adjacent-RF are configured as three...

... Abstract Glass reinforced epoxy (GRE) lining is a polymer composite material, the main components of which are a thermosetting resin and a fiberglass reinforcement. The combined properties of its components result in a material with excellent chemical, thermal and mechanical performance. GRE...

... interpretation. From the formation damage study, biopolymer was highlighted as a limiting damage mechanism. This prompted both Equinor and Schlumberger to look at alternative ways to provide rheological support without using biopolymers. A mono-valent biopolymer free reservoir drill-in fluid was designed...

.... While the severity of the skin may vary from well to well the mechanisms of damage are generally mechanical, chemical, biological, or thermal in nature. Whereas a formation with no damage would have a skin factor of zero a well with serious damage may have a skin factor of 20 or greater. Formation...

..., and this has been widely concerned. In this paper, we firstly reviewed and summarized the main damage mechanisms during the hydraulic fracturing of tight and shale reservoirs, including formation damage induced by fluids invasion, rock-fluids and fluids-fluids incompatibilities, proppants compaction...

... and water/oil interfacial tension. While the mechanism of interfacial tension reduction is well-established, the mechanism of surfactant-driven wettability alteration is still up for discussion. This study aims to give insight into the matter by investigating the surfactant adsorption and desorption process...

... during flowback. While coreflooding is useful for comparing the performance of different flowback aids, it is unable to resolve the mechanisms associated with porescale transport. The goal of this study is to directly visualize and quantify the pore-scale dynamics of fracturing fluid injection and oil...

The incorporation of a delay mechanism in the slow release asphaltene additive will provide increased protection as the well ages. This method allows longer protection time and affords a more cost-effective...

... of the relative injectivity index, β. Abstract Adequate well injectivity is required to successfully inject large volumes of CO 2 through a minimum number of wells. Brine vaporization in the wellbore vicinity has been identified as a major CO 2 injectivity impairment mechanism especially in deep saline...

While this damaged or"crushed" zone has been a subject of numerous studies involving sandstones, the specific mechanisms of perforation damage in carbonates and theeffect on flow efficiency are not well understood. We examine the carbonate crushed zone at a fundamental level by interpreting...
