The Coupled Effect of Fines Mobilization and Salt Precipitation on CO2 Injectivity

open access: yesEnergies, 2017
In terms of storage capacity and containment efficiency, deep saline aquifers are among the best candidates for CO2 storage. However, salt precipitation in the wellbore vicinity and fines mobilization ensued from in situ mineral dissolution could impair ...

SOME CLASSIFICATIONS OF MONOIDS BY VARIOUS NOTIONS OF INJECTIVITY OF ACTS [PDF]

open access: yesJournal of Algebraic Systems, 2021
This paper is a continuation of recent researches concerning generalization of injectivity of acts over moniods, namely, C-injectivity and InD-injectivity. We introduce new kinds of injectivity, such as, LC-injectivity and CQ-injectivity. Classifications

On C-injective generalized hyper S-acts [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2023
This paper explores generalized hyper S-acts (GHS-acts) over a hypermonoid S as generalizations of monoid acts within the context of algebraic hyperstructures.

ORDER DENSE ESSENTIALITY AND BEHAVIOR OF ORDER DENSE INJECTIVITY [PDF]

open access: yesJournal of Algebraic Systems, 2020
In this paper, we study the categorical and algebraic properties, such as limits and colimits of the category Pos-S with respect to order dense embeddings. Injectivity with respect to this class of monomorphisms has been studied by the author and used to

Experimental and numerical model of anisotropic permeability and CO2 injectivity of coal during CO2 enhanced coalbed methane recovery process

open access: yesFrontiers in Earth Science, 2023
Guaranteeing CO2 injectivity has been the precondition for implementing the CO2-enhanced coalbed methane recovery (CO2-ECBM), however, it dramatically decreases during the CO2 injection process because it is influenced by the dynamic change of the ...

ON REGULAR PRIME INJECTIVITY OF S-POSETS [PDF]

open access: yesJournal of Algebraic Systems, 2021
In this paper, we define the notion of regular prime monomorphism for $S$-posets over a pomonoid $S$ and investigate some categorical properties including products, coproducts and pullbacks.

(r,t)-injectivity in the category $S$-Act [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2019
In this paper, we show that injectivity with respect to the class $\mathcal{D}$  of dense monomorphisms of an idempotent and weakly hereditary closure operator of an arbitrary category  well-behaves.

Experimental and theoretical investigation of the mechanisms of drying during CO2 injection into saline reservoirs

open access: yesScientific Reports, 2023
A viable CO2 storage resource must have sufficient storage capacity, reliable containment efficiency and adequate well injectivity. Deep saline formations stand out in terms of storage capacity and containment efficiency. However, formation brine dry-out

Factors affecting the effectiveness of the application gel-forming dispersed compositions in chemical methods of oil recovery improvement

open access: yesИзвестия высших учебных заведений: Нефть и газ, 2022
The use of enhanced oil recovery (EOR) methods has a significant impact on the current level of hydrocarbon production. Therefore, the issue of maintaining the high efficiency of their application remains relevant at all stages of field development ...

Waterflood-induced fracture or "Two-Step-Rate-Test" to improve reservoir injectivity

open access: yesИзвестия высших учебных заведений: Нефть и газ, 2023
Low permeability reservoirs (less than 1 mD) are developed by intensive waterflooding. The agent is injected at pressures higher than the fracturing pressure, so that in almost every well involved in this procedure, there is spontaneous growth (injection)
