Drilling Practices (DP) - Stand-alone Chapter of the IADC Drilling Manual, 12th Edition

Drilling Practices is a straightforward explanation of the causes of troublesome drilling problems and how to avoid and overcome them. This practical guide covers:

- Bit and drilling dysfunctions, including bit balling, bottomhole balling, interfacial severity and vibrations; connection practices, including applying and removing WOB, surge and swab, and torque and drag;
- Reaming for hole conditioning, including general reaming, reaming rotary speed, swelling formations, vibrationally induced borehole patterns, hole instability, enlarged holes and more;
- Hole cleaning in directional and horizontal wells, including the dynamics of cuttings beds, pack-offs and resulting drag on drill pipe and tool joints;
- Tripping practices in horizontal and directional wells;
- Wellbore stability, including instability and hole enlargement in shales, sands, salt and tar, and hard formations; fluid chemistry and stability, borehole surveillance and downhole pressure management;
- Lost circulation, from types to practices.
