Unconventional/complex reservoirs

Oil isn’t going away, but that misses the fact that a demand plateau will structurally change the industry for people and companies in the most geologically mature areas, especially the United States.

A lot has been learned about shale, but those working to eke out oil from that ultratight rock still extract more value from data than physics.

Physics-based simulations plus machine-learning exercises are yielding a more comprehensive look at production volumes from unconventional assets.

Shale producers have learned in recent years that their fracture plugs may not be holding up as well as they thought. One of the first operators to realize the true scope of the issue is now sharing the pathway it took to solving it.

Success at the Fuling gas field in southwestern China will play a major role in the country's energy agenda.

The acquisition adds 2 or 3 years to Enerplus Corporation's development inventory, it said of the cash deal that follows its purchase of Bruin E&P earlier this year.

A look behind-the-scenes reveals what it takes to protect innovative ideas in the fast-moving US shale sector—key lessons learned, pitfalls to avoid, and how to do it the right way, as told by two of the operator's intellectual property (IP) protection leaders.

The supermajor would be the second to conduct a hydraulic fracturing pilot project in the country.

The water-shutoff technique is used in some wells of the U reservoir in the Iro field of the Oriente Basin in Ecuador to restore production after an early water breakthrough. This paper compares the production historical data, workovers, and sand-body correlation of wells to understand reservoir behavior, shale-baffle-sealing continuity, the existence of different san…

The authors demonstrate that alternating injection of polymer and water is effective and economical for heavy oil fields, even offshore.
