The optimization of drilling operations is an ongoing necessity since the major proportion of
the terrestrial hydrocarbon reservoirs has been exhausted. Furthermore, there is a growing …

This paper studies the integrated effect of double cutters on cutting rock. The rock being cut
is subjected to hydrostatic pressure. Double cutters paralleled to each other and separated …

Polycrystalline diamond compact (PDC) cutter is the key component of PDC bits, whose rock-
breaking characteristics are particularly crucial for the bit performance. Based on the …

Abstract The PDC (Polycrystalline Diamond Compact) bits are the most widely used bits in
oil drilling engineering, in order to further improve their longevity and ROP (Rate of …

The Stinger PDC cutter has been widely used for deep hydrocarbon and geothermal drilling
because it can significantly improve the rate of penetration (ROP) and extend PDC bit life in …

The main purpose of this paper is to present our polycrystalline diamond compact (PDC)
cutter model and its verification. The PDC cutter model we developed is focused on a PDC …

Abstract The relationship between Mechanical Specific Energy (MSE) and the Rate of
Penetration (ROP), or equivalently the depth of cut per revolution, provides an important …

Cutting rock in pressurized conditions is essentially different as compared to the ambient
conditions. Under pressurized condition, cutter is not only fragmenting the rock matrix, but …

Abstract Polycrystalline Diamond Compact (PDC) bits account for most of the footage drilled
in the oil field. Abundant information relating to cutter-rock interactions and rock breaking …

Although experiments and simulations of new polycrystalline diamond compact (PDC) tooth
cutting have been conducted, the rock breakage and temperature variation of the worn PDC …
