Stratigraphy and depositional environments of the Late Jurassic Hanifa Formation along the Tuwaiq Escarpment, Saudi Arabia
(2017-06-26)
A sequence stratigraphic framework of the Late Jurassic (Oxfordian) Hanifa Formation at its exposure in Central Arabia is presented for the first time. This study offers the first high-resolution stratigraphic framework ...
Sand distribution along shelf-edge deltaic systems : a case study from eastern offshore Trinidad
(2010-12)
The study area is situated along the obliquely converging boundary of the Caribbean and South American plates offshore eastern offshore Trinidad. Major structural elements in the shelf break and deep-water slope regions ...
Lithofacies, biostratigraphy, chemostratigraphy, and stratal architecture of the Boquillas Formation and Eagle Ford Group : comparison of outcrop and core data from Big Bend National Park to Maverick Basin, Southwest Texas, USA
(2015-05)
The late Cretaceous-aged Eagle Ford and Boquillas Formations were deposited on the Texas paleoshelf during a major transgressive sequence wherein organic-rich mudrocks accumulated across the paleoshelf. This study investigates ...
An investigation of anisotropy using AVAZ and rock physics modeling in the Woodford Shale, Anadarko Basin, OK
(2012-05)
The Woodford Shale formation is currently an important unconventional gas resource that extends across parts of the mid-continent of the United States. A resource shale acts as source, seal, and reservoir, and its ...
Characterizing transitional flow deposits in the proximal Brushy Canyon Formation, Texas
(2015-12)
Transitional flow deposits are identified, characterized, and placed in a stratigraphic context in the proximal Brushy Canyon Formation, Guadalupe Mountains, Texas. Transitional flows are sand-laden, mud-rich sediment ...
Sedimentology and reservoir characterization of the Upper Pennsylvanian Cline Shale, Midland Basin, Texas
(2016-08)
The Cline Shale, an organic rich mudrock comprising the Canyon and Cisco Groups in the Midland Basin, has recently become an exploration target and production interval. The Cline is a basin-restricted facies specific to ...
Three-dimensional gas migration and gas hydrate systems of south Hydrate Ridge, offshore Oregon
(2011-05)
Hydrate Ridge is a peanut shape bathymetric high located about 80 km west of Newport, Oregon on the Pacific continental margin, within the Cascadia subduction zone’s accretionary wedge. The ridge's two topographic highs ...
The comparative osteology and phylogenetic relationships of lepidosirenid lungfishes
(2011-05)
Lepidosirenidae is a clade of freshwater lungfishes that comprise the South American Lepidosiren paradoxa and four African species of the genus Protopterus. These two genera have been geographically separated since the ...
Use of high resolution 3D seismic data to evaluate Quaternary valley evolution history during transgression, offshore San Luis Pass, Gulf of Mexico
(2015-05)
A novel, shallow-investigation, high-resolution 3D (HR3D) seismic acquisition system has been employed, for the first time in the Gulf of Mexico, to characterize CO₂ storage potential and de-risk targets for sequestration. ...
Experimental investigation of ice-covered deltas : the effects of ice cover on delta morphology
(2016-05)
Deltas are dynamic systems that can provide important information on past climate conditions (Helland-Hansen and Martinsen, 1996; Hill et al., 2001; Kim et al., 2006; Bianchi and Allison, 2009). Arctic deltas have the ...
