Chemical Inhibition

The consolidation process and the overburden pressure forces water out of the shales. Relief of the confining force and re-exposure to water causes the water to adsorb very strongly onto the clay surfaces. The following changes also occur.

FUNCTIONS OF A DRILLING FLUID
Drilling engineers know that muds have many functions in the drilling operations. At any one time in the operation, one function may be more important than the other functions for that drilling interval, which is why a mud program is essential in well planning. Some publications may list ten to fifteen different functions of a drilling fluid. Many of these are variations of the same function.

Himalayan Collision

An excellent animation of Himalayan formation, featuring captions that date events in the formation of the Himalayas. Shown as a cut-away view of the earth, it's possible to see not only the continental collision, but also the mantle and the mountain root that is created in the collision.
