G&G:

Block is covered by seismic data from different vintages:

  • 1,270km (42 lines) acquired in 1981,1982 and 1988 by previous operators.
  • 1,810km (40 lines) acquired and processed in 2013 by TAOL
  • One well DRO -1 drilled within the block and 10 wells in the vicinity used for calibration 
Leads & Prospects:

Most attractive Plays :

  • Albo-Aptian Deepwater Turbidites and slope fans plays _ basin / lower slope
  • Lower Cretaceous shelf edge carbonate plays _ shelf edge/upper slope
  • Albo-Aptian deltaic complex plays _ upper slope / shelf

Further the petroleum plays extend from proximal to distal environment:

  • On the shelf, fluvio-deltaic complexes in Albian and Aptian units and Pro-delta deposits, upper slope carbonate build-ups and erosional features
  • In the basin and on the lower slope, basin floor fans and slope fans.

A total of about 38 Leads have been mapped in structural, stratigraphic and combination type within  Maastrichtian, Albian and Aptian.
