PROGRAM OVERVIEW

In response to oil and gas companies increasing interest and activity levels in the offshore hydrocarbon provinces of Africa,

ION designed the Africa BasinSPAN™ surveys to improve the understanding of the petroleum systems in and around the

continent. Collectively, the surveys provide the industry with its first regionally consistent advanced seismic datasets around

Africa - seismic programs specifically designed to provide better understanding of the multiple, active petroleum systems that

exists around the continent. In addition, each of the geologically planned surveys that make up Africa BasinSPAN datasets

have included the active participation of national and international oil and gas companies and regional experts.

AfricaSPAN programs:

→ NigeriaSPAN™ – Gulf of Guinea (~5,000 km); Republic of Nigeria (~7,000 km)

→ EquatorSPAN™ – offshore northern Gabon (~2,700 km)

→ CongoSPAN™ I and II – Two phased study of offshore Angola, Congo and Gabon (~27,000 km)

→ Gabon Deep Tow – Study of Southern Gabon (~700 km)

→ East AfricaSPAN™ – offshore Madagascar, Kenya, Tanzania (1-4), Seychelles, Mozambique and Comoros (~37,000 km)

→ LibyaSPAN™ – offshore Libya (~6,800 km) and legacy reprocessed (~38,000 km)

→ NamibiaSPAN™ – offshore Namibia (~10,000 km)

PROGRAM OBJECTIVES

→ Better understand the petroleum systems along the western and eastern coasts of Africa

→ Provide insight into current plays and their regional settings

→ Provide exploration and production companies with the data needed to evaluate hydrocarbon prospects around Africa and

build potential for new and frontier areas

KEY COMPONENTS

→ Acquisition and processing parameters and workflows were especially optimized for deep imaging objectives

→ Enhanced imaging of pre-salt depocenters (CongoSPAN), basement architecture, and rift-based tectonic features

→ Improved understanding of source rock distribution and subsequent migration pathways

→ Ties key structural and depositional features with significant wells

→ Interpretation uses well tops from database where available

ABOUT BasinSPAN™BasinSPAN surveys are geologically inspired, basin-scale seismic data programs acquired and depth-imaged using the most advanced geological and geophysical processing tools available. They provide upstream companies with the ability to evaluate the geologic evolution, deep basin architecture and depositional and structural histories of entire petroleum systems in a region. Our global 2D BasinSPAN library consists of data from virtually all major offshore petroleum provinces providing asset managers significant risk mitigation as they develop exploration and appraisal programs with greater confidence.
