Petroleum Solution Services commit organize practical fieldtrip that create real value once back on petroleum system evaluation of Mesozoic and Cenozoic Basin in onshore and offshore Vietnam.
Clastic reservoir (Oligocene, Miocene) is one of the main objectives in Cuu Long, Nam Con Son, Phu Khanh Basin. Understanding characterization of clastic reservoir is important in strongly supporting to exploration and development phase, it is very helpful to gaining practical knowledge such as type of clastic reservoir and relationship between lithology, structure and environment from specific outcrops. This field trip will help participants to understand relationship between sedimentary deposition process and petroleum characteristic. In development period, clastic field trip will help participants apply these geological concepts (facies analysis) advantageously in combination with seismic data to build geological model, optimizing location target and objectives for development wells.
Fractured Pre-Tertiary Basement reservoir is also key targets of Cuu Long, Nam Son Son Basin. The results from drilled wells recently demonstrated very complicated. Deeply understanding characterization of Fractured Pre-Tertiary Basement reservoir is important in strongly supporting for geological modeling (Halo, ANN, CFM, DFN concepts), production well design and production management. The objectives of this fieldtrip will be to give participants an overview regional geology, stratigraphy, tectonic deformation, faults and fractures characteristic in basement. It is also very helpful to gaining practical knowledge such as type of fractured basement reservoir and relationship between lithology and fault, associated fractures distribution in order to predict tension and shear fracture in basement for well design.
Petroleum Solution Services organized successful field trip recently as below:
Regional Tectonic Evaluation, Fault and Fracture Characteristics in Fractured Basement Reservoir: Pre-Cenozoic Basement in Cuu Long, Nam Con Son Basin are composed mainly intrusive and extrusive rocks which were exposed at onshore along coast of Long Hai, Phan Rang, Phan Thiet Da Lat areas and Con Dao Island.
- Ho Chi Minh – Da Lat Field Trip Route: HCMC- Long Hai – Phan Thiet – Ca Na – Phan Rang – Da Lat – HCMC
Geological Map and Outcrops of Da Lat Zone
- Con Dao Island Field Trip Route: Lo Than – Trau Te Pass – Tau Be Cape – Co Ong Airport – An Hoi – Ca Map Cape – Dau Doc
Geological Map and Outcrops of Con Dao Island
Structural characteristic, sequence stratigraphy, tectonic evolution and petroleum system of Mesozoic Basin in Southern Vietnam: Mainly outcrop exposed An Giang – Hà Tiên – Kien Luong areas and Phu Quoc Island:
- Ho Chi Minh – An Giang – Kien Luong – Ha Tien Field Trip Route: HCMC- Long Hai – Phan Thiet – Ca Na – Phan Rang – Da Lat – HCMC: Observe the Devonian, Carboniferous- Permian, Triassic, Cretaceous, Tertiary clastic, carbonate stratigraphy, intrusive and extrusive rocks and their deformation.

- Phu Quoc Island Field Trip Route: The tear-shaped Phú Quốc is NW part of the Kiên Giang Province, Vietnam and situates in the Gulf of Thailand. The Island is about 50km long from North to South and about 25km wide from east to west at its widest part being the largest one of Vietnam. Island surrounded by more than 40km of white sand beaches decorated with coconut palms and steep cliffs. In the NE part of the Island National Park with mountainous topography with some peaks reaching more than 400m, meanwhile in the SW the relief is gentle and plane. Clastic continental sediments have formed the Phú Quốc Formation and attributed to Cretaceous and Cenozoic. They formed on intracontinental depression with north-south strike. The Phú Quốc Island is located in the eastern part of the depression forming a monoclinal of west ward gradual angle of dip. The field trip will largely be devoted to the study lithology, facies analysis and their environments as well as sequence Meso- Cenozoic stratigraphy. The trip can be divided into 3 parts: south, central and north sections.

North and Northeast Vietnam Field Trip Route: North and Northeast Vietnam and adjacent areas belong to the Southeast part of Eurasia lithosphere plate, including the Sino-Vietnam, Indochina, Sibumasu composite terrannes originating from Gondwana, with different Tethys generations of continuous accretion and Paleopacific interaction (Metcalfe, 2005; Tran Van Tri et al., 2009). The geological structure and tectonic of the Northeast Vietnam are very diversified, comprising the Hoang Lien Son metamorphic terrane, East Bac Bo polyepisodic orogenic subsystem, Song Hien – An Chau Late Permian – Mesozoic intercontinental rift. Tertiary sedimentary basins in the Northeast Viet Nam were mainly distributed along the NW-SE trending fault zones: Song Hong (Red River), Song Chay (Chay River), Song Lo (Lo River), Cao Bang-Tien Yen, found both onshore and offshore. The main litho-facies association was formed in alluvial, proluvium, fluvial-lacustrine depositional environments with coal traces in places. Within the Red River, Chay River, Lo River valleys, Tertiary sedimentary basins are exposed at Bat Xat, Lao Cai, Trai Hut, Van Yen, Yen Bai, Tinh Cuong, Co Tiet, Trung Ha, Bao Yen, Doan Hung, Tri Quan-Phan Luong basins. In the NE Viet Nam region, the Cao Bang, That Khe, Na Duong Tertiary sedimentary basins associated with the Cao Bang-Tien Yen fault zone. This trip will help participants understand geological setting, tectonic evolution and petroleum system of An Chau, Song Hong, Phu Khanh Basin.
