This is a Workover advanced course that targets people who have already started working in the oil industry in general. Actually, this course is a continuation of our first course, the workover introduction course, so it is advanced in comparison to the first one. I created this course to show what I have experienced in the fields supervising different types of jobs. This course is great if you want to keep up to speed with the other workers who have already started working in the field prior to you joining. The oil and gas industry has an enormous impact on all aspects of daily life. A workover is any operation done on, within, or through the wellbore after the initial completion. Although proper drilling, cementing, and completion practices minimize the need, virtually every well will need several workovers during its lifetime to satisfactorily fulfill its purpose. This course looks at the workover operations that are done because the well is not performing up to expectations. In addition, it sheds the lights on the equipment used while performing the workover operations. Main concepts of this course will be delivered through lectures, and readings. After every lesson, learners will take short quizzes to test their newly acquired knowledge. After completing this course, you are supposed to have a good knowledge about several Workover operations.
