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.
NORM in the Petroleum Industry:
This course provides a general understanding of Naturally Occurring Radioactive Materials (NORM) in the petroleum industry. Because NORM contamination is so widespread in the petroleum industry, all personnel should be informed of the potential hazards associated with NORM exposure. The course examines the origins of NORM in reservoir formations and the processes whereby these materials are produced at the wellsite. The course explains NORM contamination in oil and gas production facilities as well as radon contamination in natural gas facilities. Animated graphics of the depositional processes help students visualize the sequence of events.

Oil Spill Volume Estimation:
Oil Spill Volume Estimation introduces techniques for estimating the volume of an accidental oil spill. Determining the volume of accidental hydrocarbon discharge is rapidly becoming one of the most important aspects of maintaining an environmentally sound offshore production operation. Reporting the amount of accidentally-released oil in the environment during day-to-day operations (a legal requirement in most countries) has proven to be a major problem due to the non-intuitive manner in which hydrocarbons disperse over a body of water. By using color photographs of actual spills, this course trains operations personnel to correctly estimate the size of an oil spill. The photographs used in this module are part of the comprehensive archives of the International Tanker Owners Pollution Federation (ITOPF) in London, and have been carefully categorized by the volume per unit area they represent. A systematic method of estimating the size of a spill is presented here in a clear, step-by-step set of procedures that can be used by field operators with no previous experience. A working knowledge of these techniques is also valuable for personnel in administrative and support roles, who may have to deal indirectly with the consequences of an accidental oil spill.
