(Grant reference: GPTL/BPX/MB/NB/89573) for permission to publish this manuscript delayed for publication due to confidentiality issues since May 2017. We warmly give thanks to many colleagues at BP's Carbonate Centre of Expertise (UK) for fruitful discussions on continental and ‘Pre-salt’ carbonates. We are indebted to Ian Billing, who recently died, for supporting this project and his encouragement towards developing experimental approaches to understand the formation of carbonate reservoir textures. Tony Sinclair, Bob Knight and Dr. Jorg Hardege (University of Hull) are kindly thanked for technical support. JR thanks the College of Petroleum Engineering & Geosciences for additional support. Prof. Adrian Immenhauser is thanked for his constructive criticism on an early draft. We are grateful for the comprehensive and useful reviews which greatly improved the final version of the manuscript.
