ION releases initial offshore Libya seismic data

Offshore staff

HOUSTONION Geophysical has completed initial pre-stack depth migration imaging from its offshore LibyaSPAN 2D seismic survey, acquired in collaboration with China’s BGP.

This is a basin-scale, multi-client survey designed to provide improved understanding of Libya’s entire offshore subsurface. Around 6,800 km (4,225 mi) of data are currently available.

ION says its main objectives were to:

  • Obtain imaging of the deep section and crustal architecture for the entire offshore area (not previously imaged)
  • Constrain the structural evolution and validity of various tectonic models for the deepwater areas of the Sirte basin
  • Understand the potential for extensions of Egyptian and Tunisian petroleum systems
  • Investigate the distribution and characteristics of known and suspected Libyan offshore reservoirs and source rocks
  • Map the extent and thickness of Messinian evaporates and of volcanic rocks that form prominent seamounts in the central Mediterranean Sea
  • Constrain the structural evolution of the complex Cyrenaica margin offshore northeast Libya.

Data includes more than 30 well tiers along new SPAN lines, and fully integrated geologic and geophysical interpretation (seismic, well, gravity, magnetics data).

ION adds that the dataset will be imaged in accordance with BasinSPAN standards and tied into the LibyaSPAN program to create what it claims will be the most comprehensive picture of the Libyan offshore.

All data is available exclusively through ION and Libya’s national oil company.

ION plans further data acquisition onshore to investigate relationships between known producing fields, and possible ties to the offshore provinces.
