Course Curriculum

Chapter 1 Blowouts
1.1
Blowouts

Defines the blowout and introduces the terrible consequences of an uncontrolled blowout on causing injury to personnel, loss of rig, and harm to the environment. Then, introduces the kick and examines how a kick is caused by pressure differentials and how a kick can turn into a blowout.

Chapter 2 Formation Pressure
2.1
Formation Pressure

Offers a comprehensive look at Formation Pressure deep underground. First, introduces the concept of porosity- taking a look at formation rocks at a molecular level. Then, examines underground pressures both before and after drilling begins, taking a look at what pressures are removed during drilling operations. Lastly, examines the Formation Pressure Gradient and walks through how formation pressure can be mathematically calculated. Student must interact with and answer a question to complete lesson.

Chapter 3 Hydrostatic Pressure
3.1
Hydrostatic Pressure

Examines the pressure exerted by a column of fluid, both in and out of the wellbore. Derives the generally accepted equation for hydrostatic pressure in a well and walks students through examples. Interactive, in-module questions require student to read, answer, and think about question while going through the lesson.

Chapter 4 Pump Pressure
4.1
Pump Pressure

Introduces friction and examines how frictional losses act against any movement along a surface.Identifies Pump Pressure as the pressure needed to overcome the frictional losses throughout the entire system. Lastly, explains how Annular Friction Loss can contribute to bottomhole pressure.

Chapter 5 Kick Theory
5.1
Kick Theory

Puts together Formation Pressure and Bottomhole Pressure to examine exactly what causes a kick to occur.

Chapter 6 U-Tube Effect
6.1
U-Tube Effect

Uses animation to indicate the exact location of the U-Tube within the wellbore. Then, introduces the U-Tube effect with an example.

Chapter 7 Lost Circulation
7.1
Lost Circulation

Explains the second part of Kick Theory; the consequences of letting Bottomhole Pressure become too much larger than Formation Pressure. Through animation, demonstrates how Lost Circulation can cause True Vertical Depth to fall and cause a kick to occur.

Chapter 8 Surface Pressure
8.1
Surface Pressure

Explains the pressure felt on rig surface equipment and the consequences of exceeding the maximum surface pressure limits of well equipment. Creates an analogy to compare wellbore surface pressure with surface pressure felt on the cap of a shaken soda bottle.
