Logbaba is a very interesting block from a seismic point of view, with complex main and secondary fault systems.
The cleaning of the seismic acquisitions to avoid the artificial noise mixed with the passive seismic data was a difficult and sensitive work.
Nevertheless the objectives of the pre- and data processing were achieved efficiently, finding a good data correlation in the Logbaba natural gas and condensate field, as well as identifying interesting potential zones.
The new potential zones derive from the signals’ properties such as resonance signature typical for hydrocarbon reservoir.

The Iso-Energy Spectrometric map (RHI map) is the final result of the Passive Seismic
Interferometry Geospectra IPDS® processing technique.

• Areas with higher values of RHI represent areas with higher likelihood of
  hydrocarbon accumulations.
• Two areas have been highlighted in red in the Figure below and they represent
  potential exploration targets.
• The location of Well X is placed at the limits of one of these areas.
• Only where there is consistent well control would it be possible to derive a
  direct correlation with hydrocarbon column thickness. One well is not
  sufficient to determine a reliable correlation.
