LESSON 3 QUESTIONS

The area, of drilling fluids is a large and complex one, and studying it can require knowledge of chemistry, physies, and math. This lesson has given an introduction to the basics of drillings. The following questions should help in studying the material in this lesson. Review the on sections Introduction and Drilling Fluid Composition and Properties. Then answer first set of questions.

1. When added to water, a good drilling clay will

A- Hydrate.

B- React with the inert fraction. C- Thin the mud.

D. Increase viscosity.

2. The reactive portion of the drilling mud is sometimes called the

A- liquid phase.

B- Colloidal fraction.C- Inert fraction

D- Emulsion.

3. The plastic viscosity of a drilling mud depends on.

A- The strength of the electric charges on the solid paricles in the mud.

B- Mechanical friction in the mud.

C- High yield point

D- The concentration, size, and shape'sh
