Shaped Cutter Performance Optimization Through Advanced Drilling Simulations
IADC/SPE International Drilling Conference and Exhibition, 2022Abstract Historically polycrystalline diamond compact cutters have consisted of a planar cutting face on a cylindrical diamond table. For decades industry has been aware of the potential drilling performance gains from forming these cylindrical cutters into other geometrical shapes.

Development and Verification of Triple-Ridge-Shaped Cutter for PDC Bits
SPE Journal, 2022Summary 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 understanding on rock-breaking characteristics of various shaped cutters, the multiridge-shaped cutter has been developed to improve the cutting ...

Rock-breaking performances of innovative triangular-shaped polycrystalline diamond compact cutter
Review of Scientific Instruments, 2021Due to high hardness and high abrasion, conventional planar polycrystalline diamond compact (PDC) cutters can easily get broken and dull when drilling in (ultra-)deep formations. To enhance the drilling performance, an innovative kind of non-planar PDC cutter, namely, a triangular-shaped PDC cutter, has been developed by altering the 2D planar cutting ...
