|Chapter 2 Pressure|
Examines pressure through several different, real-life examples. Introduces students to pressure differentials and the concept of equilibrium; setting the stage for later discussion on pressure in the wellbore.
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.
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.
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.
Balancing Well Pressures
Discusses how pressure differentials are relevant in balancing well pressures in a producing well. Specifically, introduces the concept of underbalance and overbalance and examines the consequences.
Uses animation to indicate the exact location of the U-Tube within the wellbore. Then, introduces the U-Tube effect with an example.
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 3 Well Processes & Equipment|
Intro to Drilling
Using animation, introduces students to the basic fundamentals of the drilling process. Introduces the drill bit, drill collar, drill pipe, and derrick. Then, introduces casing pipe and the cementing process. All concepts taught and explained to be accessible to students with no prior drilling knowledge.
Intro to Completions
Provides an animated look at the well completions process and all fundamental well completions equipment. Introduces downhole safety valves, landing nipples, side pocket mandrels, and multiple completions.
Intro to Production
Introduces the fundamental objectives of well production operations, including an animated and graphical look at the Christmas Tree, tubing hanger, and tubing and casing pressure gauges.

Intro to Servicing (solving downhole issues)
|Chapter 4 Kicks|
Kicks during Servicing
Looks at kicks during well servicing operations, examining the difference between a kicking well and a producing well.
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.
Lost Circulation & 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.
Explains some of the most dangerous gases experienced during oil and gas operations, exploring the properties that make them dangerous to rig personnel. Explains the low density of gas and how it can lead to gas migration when mixed together with other liquids. Introduces Boyle’s Law and the concept of gas compressibility.
In an interactive, engaging way uses the example of one gas kick to demonstrate the consequences of two different approaches to dealing with a gas kick: 1) Taking a very long time to respond to the gas kick and 2) Letting the gas kick migrate without expansion. At each stage of the kick’s movement upwards, the student must engage in many calculations.
|Chapter 5 Kick Detection|
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.
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.
