A panel of experts says US shale producers need to rethink their drilling and completion designs as problems mount for horizontal wells when they go on pump. Hanging in the balance is whether long-term production from many shale wells will be achievable.

Enventure Global Technology is working to convince operators that its solid expandable steel liners perform better than chemical diverter agents for refracturing operations. Its technology is called the ESeal ReFrac Liner.

At the recent 2015 Unconventional Resources Technology Conference, a major theme was how companies can improve performance without increasing the size of their budget.

For the past several years, automated drilling has promised to deliver major improvements in drilling performance. But the technology is facing new obstacles that might affect its progress and commercialization.

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.

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.
