ExxonMobil Integrated Hole Quality Drills With Much Higher Efficiency

Exxon Mobil technology has resulted in a world record-setting well at the Sakhalin-1 oil project in eastern Russia, enabling the production of more energy while reducing the impact on the environment.

The well was drilled from land, using the world's most powerful land-based rig and employing extended-reach technology, to a target area in the oil reservoir located under the ocean about 7 miles or 11 kilometers from shore – roughly the distance of 125 U.S. football fields.

“Employing extended-reach technology to drill onshore beneath the seafloor to offshore oil and gas deposits eliminates the need for additional offshore structures, pipelines and associated activities,” said the company

The team used ExxonMobil’s leading-edge technologies to drill the record Z-12 well in half the time needed by conventional technology.

ExxonMobil used its Integrated Hole Quality technology to manage a broad range of well variables, including rock strength and stresses and well-bore hydraulics, together with an optimization process called Fast Drill, which analyzes the amount of energy used to make the drilling process faster and more efficient.
