Understand and Apply PDC Bit-Rock Interaction Model Towards Directional Response of Drill Bit

SPE/IADC International Drilling Conference and Exhibition
Performing directional work with Polycrystalline Diamond Compact (PDC) bits have been a constant challenge since their introduction. As well trajectories continuously get more complex, more scrutiny is placed upon the drill bit design than ever before.

Field-Proven Durability, Directional Efficiency, and Cutting Structure Optimization of a Customized PDC Bit for Production Section in Deep Basin Drilling: A Case Study from Australia

SPE Annual Caspian Technical Conference and Exhibition
Drilling performance in the Cooper Basin has historically been constrained by a combination of abrasive sandstones, hard carbonate stringers, and plastic shales, which collectively create severe challenges for bit durability and directional control ...

Quantifying PDC Bit Wear in Real-Time and Establishing an Effective Bit Pull Criterion Using Surface Sensors

Day 3 Thu, September 23, 2021, 2021
It is useful during drilling operations to know when bit failure has occurred because this knowledge can be used to improve drilling performance and provides guidance on when to pull out of hole.

Modeling of Cutting Rock: From PDC Cutter to PDC Bit—Modeling of PDC Cutter

, 2021
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 cutter cutting a rock in 3D space.

Structure design of weight-on-bit self-adjusting PDC bit based on stress field analysis and experiment evaluation

, 2021
The complex formations such as soft-hard interbedded and strong abrasive strata in ultra-deep wells make the PDC bit inefficient in rock-breaking, which greatly increases the development cost of oil and gas reservoirs.
