Abstract:
In a casing-cement sheath-formation system, the cement–formation interface is usually weakly cemented for the residual of drilling mud, in which a leakage path would easily form, threatening the safe operation of underground energy exploitation and storage. To evaluate the compressive and shear mechanical behavior of the cement–formation interface, cement–rock composite cylindrical specimens were prepared. Uniaxial and triaxial compression and direct shear tests were implemented. The flushing efficiency of the rock surface, compressive strength, interface incompatible deformation, parameters o

Abstract:
Fault slip is the primary cause of casing deformation during the hydraulic fracturing process of shale gas horizontal wells. This paper investigates the mechanism of fault slip and its correlation with the integrity of the cement sheath. By establishing a numerical model of the casing-cement sheath-reservoir rock system, the effects of fracturing fluid pressure and temperature, mechanical parameters of the cement sheath, and the wall thickness of the casing and cement sheath on the integrity of the cement sheath were calculated. The results indicate that low-temperature fracturing fluids lead

Abstract:
The cement strength between the cement and the formation is a key factor in determining the cementation sealing capacity. In the shale formation, due to the organic matter content, the cementing quality between the formation and the cement ring is poor, which affects the quality of cementing. It is easy to cause problems such as annulus pressure. To improve the quality of cementing, this paper investigates the effect of amino silane coupling agents, vinyl silane coupling agents and aluminium–zirconate coupling agents on the interface cementation of rock and cement under different conditions.

Strong chemical gradients between clay and concrete porewater lead to diffusive transport across the interface and subsequent mineral reactions in both materials. These reactions may influence clay properties such as swelling behaviour, permeability or radionuclide retention, which are relevant for the safety of a radioactive waste repository. Different cement types lead to different interactions with Opalinus Clay (OPA), which must be understood to choose the most suitable material.

The dimensioning of anchor bars grouted in rock takes into account the mechanical properties of the three components steel, grout, and rock. The allowable bond strength at the rock–grout interface recommended by different national codes is generally selected according to the type of rocks and assuming an ordinary cement grout. In the present approach, the influence of the type of grout on the pull-out strength of anchor bars in a sound rock mass with mechanical properties equal or higher than the grout is considered.

It is crucial to assess the bond strength of the cement–formation interface while developing novel cements for efficient zonal isolation. An integrated method is presented to investigate the failure mechanism in cement and formation rock under downhole reservoir temperature and pressure conditions using a triaxial experimental setup. The acoustic emission count, strain, and velocity data aid in inferring the fracture process that led to the failure of a specimen. Although most specimens investigated exhibit the three dominant events of compaction, multi-cracking, and sliding, there are variati

The paper proves the feasibility of injecting highly dispersed silica fume in combination with effective polycarboxylate-based superplasticizers in cullet-based concrete mixtures.

Abstract:
We analyze analytically and numerically the stress distribution along the plug-rock interface and within an axially loaded plug emplaced in a borehole in rock. Experiments show that the interface strength increases with decreasing plug radius and with increasing plug length. Axial strength decreases as a power law of plug radius. An increase in the modulus ratio (ratio of plug modulus to rock modulus) increases the interface strength, until it levels off at a ratio of about 5.0. For short plugs, the tensile stresses may reach a magnitude significant to be of concern for long-term stability of

Through experimental debonding tests, this study aims to analyze the tensile bond strength and fracture parameters and their sensitivity to cement composition with a pozzolanic additive (fly ash).

Abstract Well-plugging and abandonment (P&A) of oil and gas wells involve the placement of barrier plugs at critical intervals in order to prevent leak paths between the reservoir and the surface.

So far, the most well-known barrier material is cement. It is well-qualified, but since it has also some limitations, other materials, such a

Abstract In oil and gas wells, cement is generally placed in the annulus between the steel casing and the rock formation to avoid migration of fluids from the formation to the well. Though, during the operation of the well, casing dilatation and contraction may lead to the loss of the sealing ability of the cement annulus: casing dilatation tends to induce cracks in the cement, while casing retractation may create casing-cement debonding (microannulus).

Abstract Cement annulus is essential to prevent the migration of geological fluids along the well. However, temperature and pressure variations in the casing may damage the annulus and create leakage paths, either cracks in the cement or debonding (microannulus) at the interface with the casing or the rock. Understanding when damage occurs, and how severe it is, is essential to ensure safe operations.
