29 Jan – 2 Feb 2023: Sedimentology, Sequence Stratigraphy and Reservoir Quality of Cretaceous Petroleum Systems of the Arabian Plate

Description

Course Program 

Day 1: Overview of the Cretaceous of the Arabian Plate and discussion of AP8 I mega-sequence.

Who Should Attend

The workshop is aimed at geoscientists involved in evaluation of acreage for licencing rounds, those concerned with the characterisation and development of carbonate reservoirs and involved in the evaluation of CCS targets.

Instructors

Cambridge Carbonates has 75+ man years of experience of exploration, reservoir characterisation, stratigraphic and palaeogeographical work based on sub-surface, outcrop and published data from throughout the Arabian Plate as well extensive experience on carbonate evaluation and reservoir characterisation projects in carbonate systems globally. In addition, Cambridge Carbonates staff are co-authors of two industry standard references that defined the Phanærozoic sequence stratigraphic framework of the Arabian Plate (Sharland et al. 2001) and described the Petroleum Geology of Iraq (Aqrawi et al. 2010).
