Introduction to Oil and Gas (Bundle)

Course Description


Taken from the Greek for ‘rock’ and ‘oil’, ‘Petroleum’ or ‘Crude Oil’ is a naturally occurring, flammable liquid, that is found in geologic formations thousands of feet below the earth’s surface.Once extracted, this crude oil is refined into a large number of consumer products, from petrol and kerosene to asphalt and chemical reagents used to make plastics and pharmaceuticals.While this short module can only cover a fraction of the history of oil and gas, we will try and uncover some of the greatest and most interesting moments, from its early use medicine and building material to modern day.

Rigs and Installations

When seismic surveys indicate the possibility of hydrocarbons, it’s time to bring in the drilling rig. Be it on land or offshore – it must be the right rig for the job. Although there are many types of oil and gas rigs, they all include a package of specialist drilling equipment and carry out the same basic drilling operations. This module will help you identify the different rig types and their capabilities and look at how rigs have evolved and how technology has advanced over time. You will also learn about the jobs and the people required to ensure safe and successful rig operations.


The exploration for oil and gas offshore only began in earnest in the 1940s and 50s but in that time offshore engineering has created many industries in towns and cities around the world. Aberdeen in Scotland, Esbjerg in Denmark, and Perth in Australia are just three examples of settlements which have seen huge growth in the number of jobs and businesses just to support the offshore oil and gas industry. Prospecting for oil and gas in the offshore environment requires a different mind-set to address the extremely harsh environments, the logistical challenges, the technological requirements and most importantly, the protection of people and assets.

Geology and Hydrocarbon Formation (Modules 1 & 2)

The term ‘Geology’ is derived from the Greek words for ‘Earth’ and ‘Study’, and this module will explain why an understanding of geology is so important to the oil and gas industry. It will help you to identify the different types of rock, and rock formations, that may contain hydrocarbons. Our planet is around 4.6 billion years old, and this module will provide a brief history of the Earth, and show you how, over millions of years, the Earth has been shaped and hydrocarbons have formed.

Drilling (Modules 1 & 2)

Our drilling modules are designed to provide learners with a general overview of the equipment and methods utilised to successfully drill a well. Subjects covered include drilling rig components and their functions, the composition of a typical drill string, the role of mud in the drilling operation, the importance of properly casing and cementing the wellbore, the different forms of Well Control and the actual techniques used for drilling the well.


Evaluation of a well is performed after we have collected data from numerous sources while drilling or at the end of drilling when the well has entered the reservoir. Data capture or ‘Logging’, as it is more commonly termed, gathers data from numerous activities and stages in the well so that its producing capabilities can be estimated and can be used to improve drilling and production performance in subsequent wells.


Once a probable location of a reservoir has been found and an exploration well drilled and tested, we will be able to tell if the reservoir could produce hydrocarbons at an economic rate and if it contains a considerable amount for future production. Basically, the testing proves that the field is economically viable and worth investing the millions of dollars required to install a production facility, drill and complete new wells.A production facility, which can range from a massive offshore structure to a simple onshore pipeline, would need to be built before we could go ahead and drill production wells and complete them. This module looks at the completion process.

Production (Modules 1 & 2)

Production processes will vary from facility to facility. Some small onshore fields are serviced only with a simple pipeline yet some major offshore installations include gas dehydration, oil storage, gas re-compression, water injection and more.The collection and processing of hydrocarbons is a very complex and varied subject. This module will look at how everyday products such as gasoline and diesel are produced from raw and natural oil and gas. As well as chapters on facilities, transportation and refining, you will also discover, with help from an interactive Process System animation, how gas, oil and water are cleanly separated directly from a well.

Advanced Techniques and Intervention

We know that technology has played a major role in the exploration for hydrocarbons. Influenced by both cost and safety, new and innovative equipment and techniques to extract oil and gas have been developed, and we will look at just a few of these in this course.Here we will explain the reasons for, and the methods of, directional drilling, how and why we might choose to drill with an underbalanced wellbore, and take a look at some of the more common means of well intervention, such as Cased Hole Logging, Slickline and Coiled Tubing.
