Power Systems and Instrumentation: The various types of power systems found on the rig are presented in this module: AC to DC, DC to DC, mechanical, hydraulic, and pneumatic drive systems. The module emphasizes the importance of prime movers, and concludes with a review of rig instrumentation.
Primary Cementing: Primary Cementing reviews the objectives of cementing an open hole. The student learns the characteristics of an ideal cementable wellbore, and how best to achieve them. The course then describes the procedures used to condition the mud prior to cementing the wellbore, including specific additives for different configurations. Furthermore, it explains the key to attaining complete mud displacement during the cementing job, and how this positively influences the success of the completion.
Kick Detection: Kick Detection trains the student to detect drilling kicks as early as possible. This course illustrates the significance of formation porosity and permeability in the development of a drilling kick. It also shows the role of the mud column in holding back the kick. Several early warning signs are explained and demonstrated through animated graphics: mud returns cut with oil, water or gas; drilling break; pit gain; change in rate of mud return; decrease in mud pump discharge pressure; increase in drill string weight; and unaccounted-for fluid gain or loss while tripping. The lesson concludes with the proper actions that must be taken to assure early kick detection. These include noting changes made to pit volumes, maintaining trip sheets, using the trip tank, investigating any sign of a possible kick, responding to alarms, and proper maintenance of PVT equipment.
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.
Units of Measure: Module 2 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.
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.
