CongoSPAN

CongoSPAN consists of two phases offshore Congo, Angola, and Gabon. Totaling over 27,000 km of acquired data, these regional 2D seismic studies include a dip and strike structural grid related to the major features of the Aptian Salt Basin. Recently, over 13,000 km of CongoSPAN has been re-imaged by ION with newly depth migrated data making the dataset an even more valuable tool when evaluating the petroleum systems in the region. 

Program Objectives

CongoSPAN I (13,000 km):

  • Provide greater insight into the post and pre-salt potential
  • Identify new petroleum systems
  • Build a foundation for crustal understanding of the margin
  • Reprocessed data using improved depth imaging technology

CongoSPAN II (14,000 km):

  • Mapping for risk reduction and better development in CongoSPAN I
  • Advanced analysis of features and petroleum potential of plays identified in CongoSPAN I
  • Improved understanding of the paleo-tectonics of the region

Gabon Deep Tow

During CongoSPAN II, 700 km of deep tow data was acquired to image below salt offshore southern Gabon. This successful technology has also been applied in several other regions, including Brazil, Nigeria, and India giving a regional scale interpretation and provides a basis for future exploration.

Key Components

  • Provide understanding of post and pre-salt hydrocarbon potential
  • Establish a foundation for crustal understanding of the margin
  • Reveal new plays and promising potential in the margin
  • Provide an improved understanding of the basement architecture of the region
  • Data depth migrated by ION totaling over 13,000 km

Using data from our BrasilSPAN and west AfricaSPAN programs, ION geophysicists and regional petroleum geologists are correlating the conjugate ties between these two regions. The data reveals striking similarities in the structural framework of the petroleum systems on both sides of the Atlantic Margin. For this reason, the Africa programs are designed to tie with our BrasilSPAN datasets, making the programs a valuable tool to E&P operators in Africa.
