Introduction of Exploration and Production
The upstream segment of the oil and gas industry covering exploration and production sectors, involves the early steps of locating and extracting hydrocarbon from the subsurface.
Exploration is a phase of finding where hydrocarbons are trapped beneath the surface by using geophysical surveys, geological analysis, and wildcat drilling. Once a discovery is confirmed, the focus shifts to applied reservoir engineering to bring the fluid into production stage.
Through this module, you will learn:
Introduction to geology and applied reservoir engineering

Completions
What is actually a well completion?
Well completion plays a vital role in the well-engineering process to design, select, and install of tools and equipment located in the wellbore for the purpose of conveying, pumping, or controlling production or injection. A suitable completion design must be safe, efficient, and economically beneficial.
