Stratigraphy and diagenesis of the Thamama-b reservoir zone and its surrounding dense zones in Abu Dhabi oilfields and equivalent Oman outcrops

We review published studies characterizing the Thamama-B reservoir zone in the upper Kharaib Formation (late Barremian) in Abu Dhabi oilfields and at outcrops in Oman. Available data for oxygen and carbon isotope compositions, fluid inclusion measurements, cement abundance and formation water compos...
