Super basins foster new technology because they possess key geologic factors and a basin-level economy of scale that fuels innovation. Global thinking improves our ability to provide abundant and affordable energy choices, and when done correctly, can also benefit economies and our environment.

Super basins are sedimentary basins with more than 5 billion BOE cumulative production and at least 5 billion BOE remaining recoverable resources. They exist offshore and onshore and have their own ecosystem encompassing the subsurface, surface infrastructure, and commercial considerations.

Pore type and pore-throat size are the major controlling factors for reservoir oil saturation in tight sandstones in the Quantou Formation, Songliao Basin, China. Pore-throat size distributions had wider ranges in the oil rich layers than in the samples lacking oil emplacement.

Yin et al. question the assumption of Wang et al. (2018) that vertical well data represent the true frequency distribution without a verification using a statistical or scientific method. Debiasing well data should be done before constructing a model. Wang et al. respond that the extent that bias is removed is difficult to assess. In some extreme cases, these debiasing methods may add extra bias to the geological model.

To better understand controls on the origin and evolution of brackish groundwater, the hydrogeochemistry of brackish groundwaters was studied within the Triassic Dockum Group across the Midland Basin in Texas. The suitability of Dockum Aquifer water for use in hydraulic fracturing fluid was examined because the area overlies the largest and most productive tight oil province in the United States.

To achieve reclamation certification, oil-and-gas operations in Alberta, Canada are required to monitor the revegetation of idle well pads that no longer support operations. Currently, monitoring is completed by oblique, helicopter-collected photography and on-the-ground field surveys.

A dramatic increase in unconventional drilling that utilizes hydraulic fracturing to extract oil/gas over the past decade has led to concern over handling and management of produced/flowback water (PFW; hydraulic-fracturing wastewater) because the potential exists for its accidental release into the environment.

Surface and airborne gas monitoring programs are becoming an important part of environmental protection in areas favorable for subsurface storage of carbon dioxide. Understanding structural architecture and its effects on the flux of fluids, specifically CO2 and CH4, in the shallow subsurface and atmosphere is helping with designing and implementing next-generation monitoring technologies, including unmanned aerial vehicles (UAVs).
