The technology is essentially the same for offshore wells, accomplished with boats and equipment modules that can be placed on the drill ship or offshore platform.

A hydraulic stimulation project must have all of this equipment linked together to be able to push a slurry of water and sand down a narrow pipe to a depth of one to two miles – and then along a lateral pipe to a distance of possibly more than a mile and a half. The pumps must overcome not only the friction of the water in the pipe, but also the natural pressure of the geologic formation at depth. Thus, many pumps working together are necessary to both overcome friction and squeeze the water and sand mixture into the fractures.

The horizontal part of the well is stimulated in multiple sections. The stimulation of each section takes a few hours and the entire hydraulic fracturing operation will be spread over two to five days.
