This workshop was targeted towards reviewing and assessing current and future approaches to improve the definition of the 3D earth model of intrashelf basins through sharing best practices and solutions to common exploration and development problems.


The Middle East Mesozoic intrashelf basins contain some of the largest oil and gas fields, with hydrocarbon resources supported by a world-class petroleum system and world-class reservoirs. In the Middle East and North Africa (MENA) region itself, the production of oil and gas from conventional reservoirs associated with intrashelf basins has provided the world with an almost continuous supply of hydrocarbons for industry, with unconventional source rocks being viewed as a future resource potential.

The IEA's 2014 World Energy Outlook acknowledged that the Middle East is still the only large source of low-cost oil. Today, several challenges exist in finding the steady supply of oil and gas from the reservoir with geology, geophysics, petrophysics, and engineering receiving focus to introduce improved workflows and new technologies. The common theme is how to image and model the 3D subsurface of intrashelf basins to economically target, find, and produce untapped hydrocarbon resources from its combined clastic and carbonate systems.

Reasons for the constraints in finding and increasing oil and gas resources may stem from a lack of understanding of the 3D geological model, and integrated techniques to overcome any shortcomings. In the MENA region, approaches to integration require introduction of new techniques and workflows with sustained effort in application to address immediate challenges.

Improving subsurface imaging and modeling practices through integrated approaches remain the only option for targeting, finding, and replacing hydrocarbon resources.
