Unconventional/complex reservoirs
The obsession with better hydraulic fracturing has steadily pushed on shale production in year one, but the decline remains steep. Chemistry could help explain, and perhaps extend, the short productive life of these wells.
The authors develop and apply a laboratory protocol mimicking leakoff, shut-in, and flowback processes to evaluate the effects of fracturing-fluid additives on oil regained permeability.
Recent history has taught the unconventional sector that overly optimistic production forecasts can backfire. Going forward, one solution may be to combine financial and subsurface models to better communicate expectations.

Just as US natural gas prices reach multiyear highs, Chesapeake Energy moves to become this region's largest producer. -
Incremental gains are not always celebrated, but as two of the biggest oil producers in the US show, they nonetheless can net unrealized savings and new efficiencies.

The combined company will have a strengthened position in the Permian Basin, and plans to operate 17 hydraulic fracturing fleets in the region.

Thousands of horizontal wells that had been drilled but uncompleted (DUCs) offered a way to maintain production without the cost of drilling more wells, but that resource is finally running low.

The third quarter has so far not seen any mergers and acquisitions in the shale business that top $1 billion.

The paper aims to determine the mechanisms of fracturing interference with multiwell pads in shale gas reservoirs and evaluate the effect of interwell fracturing interference on production.

A fast-moving pressure pulse is the priority of a research and development initiative that, if successful, will result in a new diagnostic technology for horizontal wells in tight reservoirs.

This paper describes an artificial-lift technology, a subsurface compressor system, that simultaneously removes liquids, increases gas production, and improves recoverable reserves in gas wells.
