LibyaSPAN and Libya Reprocessing

LibyaSPAN, a regional, basin-scale 2D seismic survey, was designed to create a comprehensive picture of the geology north of the Libyan coast in the Mediterranean Sea. The program ties all of the major basins and provides the deep imaging essential to understanding new exploration plays. LibyaSPAN comprises over 6,800 km of newly acquired, depth-imaged data shown in red in the map to the right.

LibyaSPAN is a collaborative undertaking between ION and BGP, and is being conducted as part of a joint agreement with Libya’s National Oil Corporation (NOC) and the North Africa Geophysical Exploration Company (NAGECO). The program lays the foundation for geologic interpretation within a consistent and calibrated framework and ties to key wells offshore. Future onshore data acquisition will study the relationships of the known producing fields and tie them to the offshore provinces.

ION is reprocessing 38,000 km of legacy data acquired in 2005, shown in black in the above map. ION has utilized improved velocity modeling from the LibyaSPAN data to create the first-time PSDM imaging on the legacy data. The reprocessed dataset is undergoing the WiBand™ processing flow for PSTM and PSDM deliverables.

Program Objectives

Obtain imaging of deep section and crustal architecture for the entire Libyan offshore, not previously imaged

  • Investigate the potential for previously unrecognised or underexplored oil and gas plays
  • Constrain the structural evolution and the validity of the various tectonic models for the deepwater areas of the Sirte Basin
  • Understand the potential for extensions of Tunisian and Egyptian petroleum systems in the Libyan offshore
  • Investigate the distribution and characteristics of known and suspected Libyan reservoirs and source rocks in the offshore
  • Investigate the relationship between Libyan onshore and offshore geology
  • Map the extent and thickness of the Messinian evaporites, and of the volcanic rocks which form prominent seamounts in the central Mediterranean
  • Constrain the structural evolution of the complex Cyrenaica margin in NE Libya

Key Components

  • Newly acquired, high-quality seismic data with improved depth imaging (~6,800 km) 
  • 38,000 km of reprocessed legacy data with first-time PSDM deliverables
  • Over 40 well ties along new BasinSPAN lines 
  • Fully-integrated geologic and geophysical interpretation (seismic, well, gravity, magnetics data)
