Well Control Primer
The premise of Introduction to Well Control course is that every member of the rig crew should understand the fundamental principles of well control to obtain the highest degree of safety dur­ing drilling operations. This self-paced course takes a rig hand through the basic concepts of well control in an easy to understand, straight-forward manner.

1. Well Control Equipment
   This module covers why controlling pressure in the well is important, the role of drilling fluid in controlling the well, BOP stacks and how they work, and the function of other equipment used in well control activities. Instrumentation used in well control operations is also discussed.
2. Units of Measure
   The second module covers units of measurement used in the oil field, calculating surface area and volume, calculating pressure, and the definition of density and how it is measured.
3. Hydrostatic Pressure
   Hydrostatic pressure discusses the linear relationship between depth and pressure, how to calculate it, the importance of true vertical depth(TVD), and how the hydrostatic pressures in different sections of a well add to determine bottom hole pressure.
4. Pressure Balance
   Topics covered in this module are how the drill string and annulus can be represented as a U-tube, differences between normal, abnormal and subnormal formation pressures, and balancing formation pressures with hydrostatic pressure of the drilling fluid.
5. Causes of Kicks
   In this module, you will learn how to identify the different conditions that can cause a kick, describe how a kick develops, describe the warning signs and the indicators of kicks, and describe the effects of a gas kick.
6. Controlling the Well
   This module covers the steps involved in shutting in the well when a kick is detected, how closing in the well can be used to increase bottomhole pressure and stop flow, why responding quickly to a kick is important, and how migrating gas in a shut-in well effects surface and downhole pressures.
7. Restoring the Well
   The final module in the IWC series covers the special problems that kicks from shallow formations present, why maintaining constant bottom hole pressure is important when handling a kick, and the steps in two methods used to restore normal circulation.
