Perforating and Stimulating
In cased hole completions (the majority of wells), once the completion string is in place, the final stage is to make a connection between the wellbore and the formation. This is done by running perforation guns to blast holes in the casing or liner to make a connection. Modern perforations are made using shaped explosive charges, similar to the armor-penetrating charge used on antitank rockets (bazookas).
Sometimes once the well is fully completed, further stimulation is necessary to achieve the planned productivity. There are a number of stimulation techniques.

Famous quotes containing the word stimulating:
“An imaginative book renders us much more service at first, by stimulating us through its tropes, than afterward, when we arrive at the precise sense of the author. I think nothing is of any value in books, excepting the transcendental and extraordinary.”
—Ralph Waldo Emerson (1803–1882)
