“…The results showed that the transverse force measured can be used to estimate rock brittleness index. The impact of scratching speed, loading rate and diamond probe radius on the critical load for scratch tests was conducted on coatings of diamond indenter [24]. Scratch testing also proved resourceful in studying the effect of bit wear in polycrystalline diamond compact (PDC) bits [79].…”

“…, and other rock mechanical parameters influencing how the fracture nucleates [5], fracture size and geometry, but fracture sizes and geometry adopted in hydraulic fracture design and modelling, Discrete Fracture Network (DFN) modeling, and Finite Element Modeling (FEM); are most often overestimated. Although scratch tests are applicable nowadays to several fields of science and engineering, ranging from strength characterization of rocks and cements/ceramics [6,7,8,9,10,11,12], to damage of polymers [13,14,15,16,17,18,19,20,21] and metals [22,23,24,25], and quality control of thin films and coatings [16,19]; the underlying rock failure mechanisms, characterization, and applications has not been fully explored. Although several researchers have attempted to evaluate and quantify UCS, fracture toughness, and other rock mechanical properties in conventional and unconventional reservoir rocks using indentation and scratch testing methods, but there remain differing opinions on the fundamental approach and principles to be adopted in estimating those parameters.…”

The scratch test is a non-destructive method made up of pushing a tool across the surface of a weaker rock at a given penetration depth. The uniaxial rock strength (UCS), fracture toughness (KIC), and other geomechanical parameters influences how fracture nucleates, but fracture sizes and geometry adopted in hydraulic fracture design and modeling are most often overestimated. Although several researchers have attempted to evaluate UCS, KIC and other geomechanical properties in conventional and unconventional formations through scratch testing method, but there remain differing opinions on the fundamental approach and principles to be adopted in estimating those properties. Therefore, the evaluation of geomechanical parameters and their effect on hydrocarbon exploration, energy storage, and hydrocarbon exploitation remain an important issue for energy industry. In this paper, we present a comprehensive review of the methods of approach, applications, and the mechanics of rock scratching. We show the merits of scratch test over other methods of estimating rock mechanical properties. Our review focuses on over 50 previous experimental studies using scratch tests in the past few decades to investigate UCS, KIC and other geomechanical properties, including their impact on rock failure, fracture initiation and propagation. Finally, we highlight the fundamental research questions that are yet to be addressed. We envisage that advancement in our knowledge will improve optimization of hydrocarbon exploitation, energy storage, and field-scale modeling for energy production operations.

“…These methods tackle the problem of severe deformations which is usually encountered in FEM simulations, however, they are computationally more expensive to use. Many studies aimed to analyse complex responses in sliding friction via experimental and numerical techniques [13][14][15][16][17][18][19][20][21][22].…”

“…However, for viscoelastic materials, this approximation is not valid, resulting in lifetime predictions that are often wrong. Therefore, in the recent past, dedicated experimental and numerical methods have been employed to study local contact phenomena qualitatively [15][16][17][18][19][20][21][22], and quantitatively [23][24][25]. Because of their transparency [26,27] and well-determined deformation kinetics [28][29][30][31][32], often an isotropic, glassy material is used.…”
