Key Risk 3: Local-Scale Over-pressurisation: Seismic/Satellite

Merged Satellite: Surface Change

Seismic: at top Storage Formation


Krechba Storage Capacity Estimation

Replace HydrocarbonsAssume all the Natural Gas is removed. Ignore dissolution and residual trapping of CO

Initial reservoir pressure = 17540 kPa at 1330 m TVD ss

Ignore dissolution and residual trapping of CO2 as it moves from injection points into the hydrocarbon structural trapGas Initially In Place = 890 Bscf = 2.52E10 sm3

pInitial reservoir temperature = 85 deg CZ-factor = 0.924 (average of PVT lab meas) Bg = 0.006523 rm3/sm3

→ Volume of h/c gas at initial reservoir conditions = 164.4E6 rm3

At initial reservoir conditions, density of CO2 = 482 kg/rm3

Vol. of CO2 equal to GIIP has mass = 163.4E6*482/1000 tonnes= 79 MM tonnes

CO2 Available to be Stored at Krechba = 14 MM tonnes


Summary & Conclusions

Storage Capacity Assessment is very site-specific and depends on the acceptable risk of leakage:depends on the acceptable risk of leakage:

1. During Operation2. Post-Closure

Site Selection and Management are Key to Determining Actual Risk of Leakage for a Project

– An Iterative Process: Data Acquisition, Analysis & Design– To manage development risk within acceptable levels

Residual risk can be managed during Operation & Closure– Site-specific process: Developer, Regulator, Civil Society– Informed by M&V and Quantified Risk Assessment
