Fractured basement reservoirs represent one of the most challenging yet high-reward play types in Indonesian petroleum systems. Productivity in these reservoirs is controlled not by primary porosity, but by fracture intensity, fault architecture, weathering profiles, and structural reactivation history.
GTN presents an integrated field-based program focused on basement fracture reservoir characterization and structural geology applications for hydrocarbon exploration. Each location provides a unique geological analog to improve subsurface interpretation and exploration risk reduction.
Theme: Granitic Basement Fracture Network and Hydrocarbon Storage Potential
Belitung exposes extensive Mesozoic granitic basement with well-developed jointing, fault zones, and weathered profiles that serve as analogs for fractured basement reservoirs in Sumatra and Natuna.
Learning Focus:
Theme: Structural Highs, Weathered Basement, and Pre-TAF Petroleum Plays
This program highlights structural highs where basement rocks are overlain by early syn-rift clastics equivalent to Pre-Talang Akar (Pre-TAF) intervals.
Learning Focus:
Exploration concept for structural drape & fault blocks
Theme: Fault Architecture, Inversion Structures, and Trap Formation in Rift Basins
This field trip integrates structural mapping with petroleum system analysis across Central and West Sumatra.
Learning Focus:
Theme: Jointed Granitic Terranes as Basement Reservoir Analogs
Bangka provides excellent exposure of granitic intrusive bodies with systematic fracture patterns comparable to subsurface fractured basement plays in Sumatra.
Learning Focus:
Theme: Structural Highs and Fractured Basement Hydrocarbon Plays
This basin is known for fractured granite and metamorphic basement highs beneath Tertiary sediments.
Learning Focus:
Theme: Transpressional Tectonics and Fracture Development
Seram offers exposure of intensely deformed rocks influenced by strike-slip and compressional tectonics.
Learning Focus:
Structural complexity in frontier exploration
Participants will gain practical skills in:
