Block area is 6,000 km2 in water depth 50-1,500m.  Working petroleum systems has been approved in the block area with various unexplored play types. Abundant HC indications and potential reservoirs from Cretaceous to Pleistocene.   F Gas Field in the block located in 120m water depth. The field reserves are over 210 Bcf in conventional clastic reservoirs. So far 36 wells have been drilled and the field is to be developed.   F Gas Field was discovered after the 1st exploration well (C-1) spudded in 1974. The major reservoirs are Late Oligocene sandstone and Cretaceous fractured sandstone with porosity ranging from 4% to 19% in 3,200-3,600m depth, and permeability 0.1md to 50md based on core lab analysis. The field is to be developed to meet the increasing gas demand in Taiwan domestic market  Petroleum System in the Tainan Basin     Source    Late Oligocene-Early Miocene shale is the major source rock and Cretaceous-Jurassic shale is the second one. The kerogen type of source rock in the Tainan Basin is commonly identified as type III/II (gas prone).Â  The TOC ranges from 0.5% to1.5% (fair-good quality) and the range of vitrinite reflectance is 0.6-1.2% Ro (early matured-matured).   Reservoir    The Late Oligocene shallow water, transgressive sandstone and the Cretaceous fractured sandstone are the main reservoirs of F field. Porosity ranges from 4%-19%. Miocene delta and turbidite sand are the high potential reservoirs. Sand bodies within the slope fan highly develop in the Pliocene-Pleistocene channel systems.   Â Seal    Miocene-Pleistocene shale/claystone serves as the regional seal. Late Oligocene shale is local seal.   Trap    Structural trap, fault-related structural trap, stratigraphic trap and structural-stratigraphic combination trap are identified.   Exploration potential     At least 6 leads in 3 different play types were identified by 2D seismic interpretation integrating with well data. Total recoverable resources were estimated more than 3.8 TCF (P50).Â  Many prospective fault blocks/traps nearby the F Gas Field in the 3D seismic area havenât yet been tested by drilling. Opportunity for operator to conduct 3D seismic survey and reprocess the vintage 2D/3D seismic data with state-of-the-art technology. Reinterpretation with better seismic image and advanced concepts help to accurately re-evaluate the E&P potential.  Exploration Play Type-1     Stratigraphic trap - Total closure area of 33 sq km, reservoir in the Early Miocene turbidite sands with porosity ranging from 20% to 25% was encountered in many wells and their DST results indicated a high possibility of gas accumulations. Bright amplitudes anomaly along the up-dip events also shows a positive indications of HC accumulations. Seal is the Middle Miocene-Pleistocene marine shale/claystone.   Prospective resources ~1.2 TC  Exploration Play Type-2     Structural-stratigraphic combination -Total closure area of 65 sq km, reservoir in the relic of Late Miocene deltaic sandstone was eroded by distributary channels. Porosity varies from 20% to 25%, and possible high permeability and high net-gross ratio. Large bright amplitudes anomaly was found nearby paleo-shelf edge. Seal is the Plio-Pleistocene mud filled channels and marine shale/claystone.  Prospective resources ~1.8 TC  Exploration Play Type-3     Structural trap - Total closure area: 69 km2, reservoir could be sand bodies within the slope fans/channels which is highly developped in the Plio-Pleistocene channel systems.Â  Porosity up to 30% predicted based on impedance-porosity relationship.Â  Seal can be the Pliocene-Pleistocene marine shale/claystone.   Prospective resources ~1.4 TCF
