unconventional resources
-
For the past quarter of a century, underbalanced drilling (UBD) has been a niche technology known to many and practiced by few. It has seen acceptance in the North Sea, where UBD is used to drill through depleted reservoirs. -
This paper aims to develop criteria for identifying situations in which induced fracture complexity and sustained conductivity are or are not required.
-
In the realm of enabling technologies, multiphase flow modeling has proven to be one of the most important to the oil and gas industry. Without it, nearly all subsea wells would be too costly or dangerous to develop.
-
In the northeastern desert of Utah, a new type of oil sands extraction technology has been born. The company behind it claims the process is the most cost-effective and environmentally sound way to develop oil sands.
-
The rapid development of shale formations over the past decade has led the United States to become the world’s undisputed leader in natural gas production.
-
This paper presents methods for production forecasting that give reasonable post-treatment predictions that have been found to be useful for economic planning.
-
The United States’ liquids-rich shale experience has been dominated by three major plays: the Eagle Ford Shale in south Texas, the Permian Basin in west Texas, and the Bakken Shale that straddles North Dakota and Montana.
-
A sharp rise in seismic events in some areas of the United States where oil and gas production is booming is leading regulators and the industry to examine whether the two are related.
-
Unconventional resources offer many substantial benefits, yet the rapid increase in production of these resources using hydraulic fracturing has generated scrutiny by some policymakers and advocates who cite health concerns.
-
It has been an impressive comeback for a technology that once stood on the brink of failure. The upstream oil and gas industry has largely resolved crippling technical challenges that shortened the life of fiber-optic cables in downhole applications and is now working on a big encore.
