I. What is a PDC Bit? A PDC (Polycrystalline Diamond Compact) bit is made by setting or sintering PDC cutters on a bit body. It is mainly used for drilling in soft to medium-hard formations. The cutting elements achieve efficient rock breaking through polycrystalline diamond composite. PDC bits break formations by sh

PDC bits have become the main bit type in water well drilling, oil & gas drilling, and geological exploration due to their high wear resistance, high drilling efficiency, and long service life. However, many field personnel have misconceptions in use, leading to premature bit failure. This article shares practical expe

In water well drilling, the drill bit is known as the "teeth that bite through rock." Choosing the right bit leads to fast drilling, low cost, and high well quality; choosing the wrong bit results in slow footage, frequent tripping, or even bit scrapping and borehole collapse. Common Formations and Drilling Difficulti

In 2026, the global drilling industry is at a critical node where the new five-year plan and energy transition overlap. With shallow resources becoming increasingly depleted and price wars compressing profit margins, deep mineral exploration, unconventional oil and gas, geothermal development, and urban underground spa
