Lastly, takes a look at the importance of Test Trees and Christmas Trees in regulating well control after drilling operations have ended.

Chapter 3 Kick Theory

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.

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.

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.

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.

Kick Theory

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

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.

Lost Circulation and Fracturing

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.

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.

Chapter 4 Fluids

Chapter 5 Blowout Prevention System
Introducing the BOP

Conceptually introduces the BOP stack and its importance in shutting-in the well to prevent kicked fluid from reaching the surface. The differences between annular and ram preventers are discussed, using 3D animations to visually demonstrate the unique attributes of each preventer. Ram elements are discussed as well as the role of the drilling spool.

Specifically, examines the major pressure gauges and the pressures read during normal circulating operations. The Pump Pressure Gauge, Standpipe Pressure Gauge, Drillpipe Pressure Gauge, and Casing Pressure Gauge are all examined.

Fluid Recording

Explains the importance of fluid measurement in detecting problems in the wellbore. Introduces the Pit Level Indicator, used to measure the amount of fluid returning to the mud tanks, the Mud Return Indicator, used to measure the speed of fluid returning to the mud tanks, and the Mud Pump Stroke counter, used to count how many strokes of fluid have been pumped into the well.

Gas Control

Reiterates some of the challenges with adequately controlling gas in the well. Introduces the gas detector and its importance in detecting gaseous fluids that are invisible to the human eye. Delves into the Mud-Gas Separator, examining its limitations and the consequences of rupture and gas blow-through when its limitations may be exceeded.

Safety Valves

Chapter 7 Causes of Kicks
Insufficient Hydrostatic Pressure

Establishes some of the different ways that hydrostatic pressure can become lower than formation pressure, causing a kick to occur. Specifically, discusses how tripping pipe out of the well can reduce Total Vertical Depth and how the mud cleaning process can sometimes remove barite and other weighting chemicals, reducing Mud Weight.


Uses powerful, downhole animation to let students visualize the suction effect of Swabbing and how it can pull formation fluid upwards into the well. Introduces Swab Pressure and explains how it acts against bottomhole pressure.


Uses powerful, downhole animation to let students visualize the water hammer effect of Surging and how it can create significant downward pressure that causes fracturing or lost circulation. Introduces Surge Pressure and explains how it acts against bottomhole pressure.

Crew Drills
Chapter 10 Kick Procedures
Shut-in Concept

Provides a detailed, step-by-step conceptual understanding of the impact of well shut-in on underground pressures. Using the example of a bottle cap, explains how shutting-in the well makes bottomhole pressure automatically equal to formation pressure.

Abnormal Circulation

Introduces the abnormal circulating path, through which fluid is circulated when the well is shut-in. Examines the path of fluid flow down the drill pipe, up the annulus, and out through the HCR valve into the choke line to the adjustable choke.

Shut-in Procedure and Verification

Defines the importance procedures involved in the well shut-in process, during both drilling and tripping operations. Also explains the importance and procedure involved in verifying that the well has successfully been shut-in.

Recording Parameters

Explains the three most important parameters that need to be recorded after shut-in: Shut in Drill pipe Pressure (SIDPP), Shut in Casing Pressure (SICP), and Estimated Pit Gain. Walks through the importance of SIDPP and SICP in understanding Formation Pressure and explains why SIDPP is generally lower than SICP.

Chapter 11 Kick Methods
Constant BHP Methods

Introduces, conceptually, the importance and power of constant bottom hole pressure well kill methods. Explains how maintaining constant bottomhole pressure can prevent additional kicks, lost circulation, and surface pressure problems.
