unconventional resources

Fabián Vera, Baker Hughes, and Christine Ehlig-Economides, Texas A&M, explain transient well analysis and how it contributes to shale development.

While shale unproved technically recoverable resources have been identified around the world, development has been limited to North America.

Some operators are returning to their North American mature unconventional shale wells to refracture, or restimulate, the rock to accelerate production and enhance ultimate recoveries.

Tight gas reservoirs and shale gas reservoirs are economically viable hydrocarbon prospects that have proved to be successful in North America.

Seizing on historic margins in domestic prices, North American oil and gas companies are increasing their efforts to use more natural gas and less diesel fuel to power their field operations.

Reserves- and resources-evaluation methods in unconventional reservoirs are different from those for conventional reservoirs.

Early in its development, the Cline shale was hyped as the next Eagle Ford or Bakken with more oil and gas than they have combined.

The rapid growth in the development of unconventional shale resources has changed business-as-usual for onshore production equipment manufacturers and suppliers.

This is the first of several articles on the subject of water management for unconventional hydraulic fracturing. This article outlines the critical issues and outlines development of a strategy for treatment of flowback fluids.

As the development of US shale plays expands to undeveloped or underdeveloped areas, the environmental issues related to surface facilities move to front and center. Operators, regulators, politicians, and the general public have become more aware of and concerned about environmental effects.
