Jan 9, 2019 · PDC bits work well in rock with PSI between 2,000 to 30,000. Because they cut so fast, issues sometime arise when not enough fluid is being pumped to clear the cuttings out of the hole. When a PDC bit sits in its own cuttings, this can cause the bit to wear unevenly and prematurely fail, even in the correct formations.Oolite. Oolite is a sedimentary rock made up of ooids (ooliths) that are cemented together. Most oolites are limestones — ooids are made of calcium carbonate (minerals aragonite or calcite ). Ooids are spheroidal grains with a nucleus and mineral cortex accreted around it which increases in sphericity with distance from the nucleus.
