> 98% of energy supply rely on imports
Energy Bill (% of GDP): 3.8%(2001) 13.6%(2012)
Emit approximately 270Mt CO2 in 2010, ~0.89% of global CO2 emission, ranked 20nd globally (IEA)
CCS will contribute 12% CO2 emission reduction, about 36.7 million tons CO2 per year in 2025 according to proposed NAMAs

CO2 capture: Large and
stationary point emitters
CO2 storage: Deep saline
aquifers and Oil/gas structures
CO2 capture: technology and commercial-scale demo & verification
before 2025 with solid sorbents or chemical looping
CO2 storage: pilot injection projects, site characterization, storage
capacity assessment, simulation and prediction of CO2 plume
migration, MMV, and risk assessment

Pressure increased and extensively
All geological formation could stand
pressure build up and regional seal

For heterogeneous permeability case,
pressure only affect CS and above

The monitoring system: big funnel
(1m x 1m) is used to cover the
bubbling gas of the mud pool
Thermo mass flow meter
recorded the flow rate every 10
minutes
Continuous monitoring since
March 13, 2008
(Cheng et al, 2013)
• CO2 accounts for 87% of bubbling gas from CL mud pool,
and its flux can be estimated 83~242 t‧yr-1 (mean =114
t‧yr-1)
• Considered the CO2 flux and the activity of the fault, more
than 900 Mt CO2 were stored in the reservoir
• CO2 emission in the fault zone of studied area is ca. 28~31
kt‧day-1 => 11 Mt/y

Natural Analogue – CO2 Reservoir
Mantle-derived gas reservoirs do
exist beneath western Taiwan
CO2 Miocene extensional
magmatism and normal faulting
and brought to shallow crust
CO2 have been stored more than
5 million years – long-term
containment
(1) Igneous Province:
High 3He/4He ratios (4.0~8.4 Ra)
magma related
(2) Central Range Province:
0.1~0.9 Ra Crustal components
(3) W. Sedimentary Province:
Mud volcanoes are crustal component
dominant (0.1~0.26 Ra)
However, unusually high ratios were
obtained (up to 6.5 Ra)

Hydraulic fracturing of cap rock

In normal faulting regime:

Pressure Increase – Fault Reactivation
Fluid injection reduces the effective nor
mal stress on optimally oriented pre-
existing faults triggering slip
• High‐permeability pathways within
the reservoir
• Induced seismicity
Buoyancy Pressure =
Critical Pore Pressure
(based on Coulomb Failure Criterion)
results in slip on optimally oriented faults (J.H. Hung and P.C. Yan, 2012)

Brief Summary of TCS field • Geomechanical analysis shows that gas injection into the
Talu sand of the TCS anticline will not induce slip on pre-
existing mapped faults or fracturing of cap rock.
• There is no documented evidence of casing failure in 40
wells due to fault reactivation or any reported leakage
indicators from monitors deployed in the surface
• In addition, there has been no induced seismicity
associated with fluid injection over the past 20 years
• The best strategy is to avoid injecting into faults, and if
pore pressure builds, wait until flow rate increase in the
reservoir.

Conclusion • CCS is an important carbon reduction technology for
Taiwan – solution and green opportunity
• Assessment of Geological Storage in Taiwan
– Adequate potential – near and off-shore
– Pilot storage projects underway – public acceptance is
an important issue
– Suitable environment for long-term storage of CO2
– Safe operation experience for underground gas
storage for decades
