Reservoir

Case studies demonstrate how an autonomous outflow-control device prevents growth and excessive fluid injection into thief/fracture zones and maintains a balanced or prescribed injection distribution.

This paper presents recent results from a rigorous pilot-scale demonstration of natural-gas foam over a range of operating scenarios relevant to surface and bottomhole conditions with a variety of base-fluid mixtures.

The complete paper reviews the history of enhanced oil recovery and the Scurry Area Canyon Reef Operators Committee, discusses changes in theory over time, and provides a look at the field’s future.

The authors demonstrate how reservoir management and operational strategies can be used to optimize CO2 storage and oil recovery.

Hydrochloric acid continues to be the most effective and low-cost material for carbonate stimulation. Though exotic chemistries such as chelating agents and organic acids have been promoted for being less corrosive at high temperatures, the cost and dissolving capacity limit their use to large-scale implementation. The ability to inhibit the corrosion tendency of hydr…

Using validated models, the authors provide a comparative analysis to determine the advantages of using natural gas foams relative to conventionally used slickwater, linear gel, and crosslinked fluid.

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.
