Drilling is the process of making a hole
or a well in the earth for some purpose.
The purposes are many and they
includ

Directional Drilling Terms
We will now create a trajectory plan for a
deviated well.
In this section several new terms are
introduced for directional drilling.
Inclination , , is the angle of the well bore
from vertical.
Compass Bearing, , also called the

Introduction to Drilling Mud
Liquid drilling mud should:
1.
Bring cuttings from under the bit to the surface.
2.
Create sufficient hydrostatic pressure inside the bore hole to
prevent reservoir fluids from flowing in. (This is not always
desired, as in un

Casing Design
Casing is large diameter pipe that is used to
1. Stabilize and seal parts of the well bore
using cement.
2. Protect shallow formations from high pressures
found in deeper zones.
3. Seal zones containing corrosive water.
4. Seal and protect

Rock Mechanics & Drill Bit Selection
To drill we must find a way to break rocks.
The drill bit is the end of the drill string that is the cutting structure
that causes the rock to fail.
In order to make the bit work we provide
1. Compression loads throug

Oil and Synthetic Oil Base Mud
Oil and synthetic oil base mud must satisfy the same requirements
as water base mud.
Oil base mud has diesel (OBM), or mineral oil or esters (SOBM) as
its base fluid.
Water is also in the mud along with an emulsifying chemic
