East Palawan and Sulu Sea PECR4 Blocks MC 2D Seismic Reprocessing Optimise bidding strategy and exploration work programs 5,740 km reprocessed Newly reprocessed MC 2D seismic data over the 4th MC 2D seismic Philippine Energy Contracting Round (PECR4) Areas 10, 11, 13 and 14 is now available. Area 10 Area 13 The data coverage and quality are appropriate to: Sulu Sea Area 11 • Establish regional geologic framework and identify, map and predict source, reservoir and seal of various plays. Area 14 • Evaluate and screen prospectivity of Philippines PECR4 Blocks and enable to formulate a competitive bidding Area 15 strategy and optimise exploration work programs. Inversion anticlinal traps Unconformity trap Carbonate build up? Rollover anticlinal trap WSW ENE Half grabens/sub-basins are potential fetch areas as the source rocks are buried more than 3 km to be mature • Potential for post-rift clastic reservoirs, as encountered in wells that are tied to the survey, are expected to be present within well imaged trapping configurations. Carbonate and syn-rift clastic reservoirs are also potential targets. • Preliminary investigation shows that the key elements of prospective plays are likely to be present in the offered blocks. • Amplitude and AVO anomalies that could be related to HC presence have also been observed. The reprocessed dataset in East Palawan and Sulu Sea PECR4 Areas records potential HC related anomalies AVO anomalies will enable to high-grade opportunities and technically support cost effective exploration work programs in PECR4 Areas Flat AVO terminations that AVO – HC Leg No AVO – Water Leg could be related to HCW contact gather locations Far angle stack (22-40 degrees) • Reservoir is expected to be submarine fan sandstones, which are proven in southern Sulu Sea HC leakage effect? • Low risk transpressional anticlinal trap that could be fault-bounded • Wet gas charge is proven in the basin where this Near angle stack example is located Anticlinal trap (5-22 degrees) • Similar AVO responses which are in the right geologic setting (with expected reservoirs within low risk trapping configurations and with access to charge) have been observed in angle stacks and gathers of the reprocessed dataset within the PECR4 Areas. • The presence of AVO anomalies would enable companies to high-grade opportunities, and formulate efficient exploration strategy and exploration work programs.
