unconventional resources

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.

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

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.

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.

An interview with Joe Leimkuhler of Shell and Greg Leveille of ConocoPhillips on unconventional resources development.

It may not matter whether the IOCs or the NOCs are in charge. The work to be done is the same and the same people will likely be doing it. Unconventional resources already comprise 40% of production in North America and they are expected to grow globally.
