Automatic Extraction of Offshore Platforms in Single SAR Images Based on a Dual-Step-Modified Model

Sensors, 2019
The quantity and location of offshore platforms are of great significance for marine oil spill monitoring and offshore oil-gas development. In the past, multiphase medium- and low-resolution optical or radar images have been used to remove the ...

Coevolution of diagenetic fronts and fluid-fracture pathways

Scientific Reports, 2022
Diagenetic boundaries are paleo-reaction fronts, which have the potential to archive the termination of metasomatic processes in sedimentary rocks. They have not been extensively studied, perhaps because they appear simple in outcrop.

Multiphase dolomitization of deeply buried Cambrian petroleum reservoirs, Tarim Basin, north‐west China

Sedimentology, 2016
AbstractCambrian dolostone reservoirs in the Tarim Basin, China, have significant potential for future discoveries of petroleum, although exploration and production planning is hampered by limited understanding of the occurrence and distribution of dolomite in such ancient rocks buried to nearly 8 km.

Fault Characteristics and Reservoir Potential of Mesozoic Basins in the Southern East China Sea

Journal of Marine Science and Engineering
The East China Sea Basin (ECSB) is an integral part of the Western Pacific tectonic system. Its development is linked to the Kula–Pacific Plate and the formation and expansion of the Philippine Sea Basin.

Structural framework and evolution of the Golfo San Jorge Basin: a synthesis

Latin American Journal of Sedimentology and Basin Analysis
The Golfo San Jorge Basin evolved through a complex multiphase structural history from the Middle Jurassic to the Neogene. Its stratigraphic record captures key tectonic events in central extra-Andean Patagonia during Gondwana fragmentation and the ...

Wellhead Choke Performance for Multiphase Flowback: A Data-Driven Investigation on Shale Gas Wells

Energies
Wellhead choke performance is critical for flowback choke-size managements in unconventional gas wells. Most existing empirical correlations were originally developed for oil and gas flow, and their accuracy for gas/water multiphase flowback remains ...

Main factors controlling the sedimentation of high-quality shale in the Wufeng–Longmaxi Fm, Upper Yangtze region

Natural Gas Industry B, 2017
In this paper, the shale of Upper Ordovician Wufeng Fm–Lower Silurian Longmaxi Fm was taken as an example to reveal the distribution patterns and the main sedimentation controlling factors of high-quality shale in the Upper Yangtze region.

Oblique reactivation of lithosphere-scale lineaments controls rift physiography – the upper-crustal expression of the Sorgenfrei–Tornquist Zone, offshore southern Norway [PDF]

Solid Earth, 2018
Pre-existing structures within sub-crustal lithosphere may localise stresses during subsequent tectonic events, resulting in complex fault systems at upper-crustal levels.

The impact of forced closure on proppant distribution of hydraulic fracturing in shale formations

Deep Underground Science and Engineering, EarlyView.
Research findings demonstrate that implementing forced closure within shale formations can remarkably mitigate proppant settlement, concurrently increasing the effective propped surface area from 29.74% to 38.68%. Abstract Forced closure is widely used in conventional oil and gas reservoirs to promote uniform proppant placement.
