Role of facies cycles on the mid-upper Cretaceous Bangestan Reservoir rock typing in the Zagros Basin

Depositional environment, seismic stratigraphy, and Sr-isotope geochronology, Bangestan reservoir, Ahwaz oilfield, SW Iran

Mehdi Khoshnoodkia et al.

Summary: The Bangestan reservoir in the Ahwaz oilfield consists of middle Cretaceous limestone formations deposited in the Zagros Basin. It is divided into ten zones with considerable hydrocarbon accumulations, predominantly rudist biostrome and grainstone facies. Seismic stratigraphy and isotopic data help understand the structural and geological setting, revealing a complex history influenced by paleogeographical changes.

New methods for qualitative and quantitative determination of wettability from relative permeability curves: Revisiting Craig's rules of thumb and introducing Lak wettability index

Abouzar Mirzaei-Paiaman

Summary: Craig's rules are widely used for qualitative determination of wettability. The first rule describes characteristics of water-wet rocks and oil-wet systems, the second rule judges water-wet and oil-wet systems based on the crossover point of relative permeability curves, and the third rule explains the relationship between interstitial water saturation and wettability. A modified version of Craig's second rule is introduced in the study, along with the new Lak wettability index.
