What is polycrystalline diamond compact?

What is polycrystalline diamond compact bit?

A polycrystalline diamond compact (PDC) bit is a bit that uses synthetic diamond disks, called “cutters,” to shear its way through rock with an ongoing scraping motion.

What does PDC stand for in drilling?

Polycrystalline diamond materials, for use in polycrystalline diamond compact (PDC) bits, are one of the most important material advances for oil drilling tools in recent years. Fixed-head bits rotate as one piece and contain no separately moving parts.

What is PDC Petroleum?

1. n. [Drilling] A drilling tool that uses polycrystalline diamond compact (PDC) cutters to shear rock with a continuous scraping motion. These cutters are synthetic diamond disks about 1/8-in.

How does a roller cone bit work?

As the drillstring is rotated, the bit cones roll along the bottom of the hole in a circle. As they roll, new teeth come in contact with the bottom of the hole, crushing the rock immediately below and around the bit tooth.

How much does an oil rig drill bit cost?

At about $10,000-150,000 apiece, PDC bits generally cost five to 15 times more than roller cone bits.

What’s the difference between titanium and titanium nitride drill bits?

Both titanium and cobalt drill bits are made of high-speed steel alloy steel. The main difference between the two bits is that the titanium drill bits are high-speed steel bits with titanium nitride (TiN) coating whereas the cobalt drill bit is made of alloy steel that contains 5 to 8% of cobalt.

What are the 4 classification sizing methods for drill bits?

IADC Classification Standards For Tooth and Button Bits

The numbers 1, 2 and 3 indicate a tooth bit with 1 being used for soft formations, 2 for medium, and 3 for hard. The numbers 4, 5, 6, 7 and 8 denote tungsten carbide inserts designed for different formation hardness with 4 being softest and 8 being the hardest.

What is the main advantage of PDC bits?

PDC Cutters enhance the performance of PDC drill bits, making them dynamically stable across a wide range of demanding vertical and directional drilling applications. Polycrystalline diamond cutter is a unique material posessing high strength, hardness and toughness.

What does PDC Energy do?

PDC Energy, Inc. is an independent oil and gas company focused on maintaining a strong balance sheet and solid debt metrics while delivering value-added organic growth from a liquids-rich portfolio through horizontal drilling.
