Integrated geological study for reservoir modeling and characterization of the Shurijeh gas bearing sandstones in one of the Northeast Iran gas fields

open access: yesPetroleum Research
The sandstones deposited in the sequence of Shurijeh Formation comprise a giant gas reservoir in the Northeast of Iran. Five primary facies (petrofacies) were identified in the deposits of Shurijeh Formation such that the entire sedimentary sequence was ...

Sandstone petrofacies in the northwestern sector of the Iberian Basin

open access: yes, 2007
[ES] Durante las fases de rifting más activas en el sector noroccidental de la Cuenca Ibérica (Cuenca de Cameros y Rama Aragonesa de la Cordillera Ibérica), se generaron potentes sucesiones detríticas de depósitos continentales. Los registros arenosos del ciclo Rift 1 (Permo-Triásico) y Rift-2 (Jurásico Superior-Cretácico Inferior) muestran similitudes
