oa Characterizing the Relationship between Petrophysical Trends and Diagenetic Cementation Patterns: A Case Study from a Carbonate Arab Reservoir in the Dukhan Field, State of Qatar

The Upper Jurassic Arab-C Reservoir in the Dukhan Field is the product of a stable epicontinental shelf subjected to continuous relative sea-level variations, with the preserved sediments representing a complex of syndepositional carbonate lithologies and textures deposited in subtidal, intertidal and sabkha environments. Though the depositional units are spatially correlated within a sequencestratigraphic context, petrophysical observations do not conform to the primary depositional fabric, and a cross-cutting relationship is observed.
