Viper Energy is acquiring Sitio Royalties Corp. and its more than 25,000 net acres of royalty interests across major US shale plays.
Extensive acreage overlap and existing operational collaboration drove the acquisition decision.
Data mining techniques are unlocking new insights from the performance of thousands of Bakken wells. This article explores how those insights are helping refine completion optimization.

This paper details new technologies and work flows implemented for Australian offshore wells to improve drilling efficiency while managing associated risks. -
The paper demonstrates the application of an interpretable machine-learning work flow using surface drilling data to identify fracable, brittle, and productive rock intervals along horizontal laterals in the Marcellus shale.
-
This paper describes the findings of a root-cause analysis of wellhead-penetrator failures in Canadian steam-assisted gravity-drainage operations and the mitigation measures taken.
-
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.
