Drilling Problems
Downhole problems cost more rig time than almost anything else. Stuck pipe, lost returns, swelling shale and vibration can turn a good well into a long, expensive one.
These articles are organized like a troubleshooting guide: what you'll see at surface, what's causing it, and what crews do first to fix it.

What Causes Stuck Pipe? – Mechanisms and First Actions
Stuck pipe comes down to three mechanisms: differential, packoff and hole geometry. Learn the warning signs, how to tell them apart and what to do first.
What Is Lost Circulation in Drilling? – Causes and Severity
Lost circulation is mud flowing into the formation instead of back up the hole. Learn the causes, seepage vs partial vs total losses, and how crews cure them.
What Causes Wellbore Instability?
Wellbore instability comes from rock stress, mud chemistry and time. Learn the mechanical and chemical causes, the warning signs at the shakers and fixes.
