With direct project exposure in the Ombilin Basin, GTN brings practical subsurface insight into field-based analog programs that bridge geology, geomechanics, and storage risk evaluation.
Below are carefully selected Indonesian locations that provide strong geological analogs for CCS/CCUS implementation.
Theme: Lacustrine–Fluvial Sandstone Storage & Structural Containment in a Rift Basin
GTN’s CCS experience is rooted in the Ombilin Basin, where thick Eocene syn-rift successions provide potential storage intervals beneath regional sealing units.
This program reflects GTN’s direct CCS basin evaluation experience.
Theme: Depleted Gas Fields & Saline Aquifer Storage Potential
Oligo–Miocene clastic systems (e.g., Talang Akar equivalents) provide large-volume saline aquifer potential.
Theme: Multi-Reservoir Storage in Mixed Clastic–Carbonate Systems
Miocene sandstone reservoirs and regional marine shales offer excellent containment geometry.
Theme: Thick Deltaic Sandstone Packages for Large-Scale Storage
Kutai’s deep, regionally extensive sandstones represent high-capacity saline aquifers.
Monitoring strategy concept (MMV framework).
Theme: CO₂ Storage in Fractured Carbonate & Structural Highs
Carbonate reservoirs pose unique challenges for containment and plume migration.
Long-term mineral trapping potential.
Participants will gain applied understanding of:
CCS success depends not only on volumetrics but on:
Field-based geological understanding reduces subsurface uncertainty before millions of dollars are invested in injection infrastructure.
