A Real Mathematical Model to Compute the PDC Cutter Wear Value to Terminate PDC Bit Run

SPE Middle East Oil and Gas Show and Conference, 2011
Abstract Drilling operations became more expensive and complicated day by day due to many reasons affecting directly the daily drilling cost. One of the most effective cost reductions was the fixed cutter bit solution which effectively achieved higher drilling progress and reduces overall well cost.

Investigation of PDC Cutter Interface Geometry Using 3D FEM Modelling

International Journal of Engineering Research in Africa, 2017
Polycrystalline Diamond Compact (PDC) cutters have been popularly used in recent times due to their resistance against mechanical and thermal wear. This paper was focused on interface geometries between the substrate and the diamond table. Various types of interfaces were designed, to investigate how different interface geometries influence ...

Single Cutter Testing – A Key for Pdc Bit Development

SPE Offshore Europe, 1987
Abstract A description is given of a single-cutter tester for studying the cutting process of PDCs in rock under simulated downhole conditions. The use of the tester is illustrated by a study of the effect of downhole pressures on the cutting process in shales. Prior to the tests the Pierre shale and Mancos shale outcrop samples used for

New Prediction Method for ROP Potential of Shaped PDC Cutters

SPE Journal
Summary Mechanical specific energy (MSE) is normally used to evaluate the rock-cutting efficiency of shaped polycrystalline diamond compact (PDC) cutters. The lower the MSE, the higher rock-breaking efficiency the cutters and the bits will have, and by default, it is considered that a higher rate of penetration (ROP) can be obtained ...
