Deliverable 4.5: CO2 storage assessment – numerical simulation of the India case study

Abstract

A study of possible CCS application at the onshore field Baghewala,Bikaner Nagaur Basin India is discussed. The primary analysis includes identification of key reservoir and caprock units for storage and monitoring. Furthermore, a simple 3D homogeneous model based upon petrophysical properties from well data is generated and simulated under different injection rates of CO2 to identify the associated changes in pore pressure. Based upon the learnings from this model, a field scale model is generated to present a more realistic study for CO2 saturation and pore pressure changes in identified reservoir units. The Geomechanical properties such as Young Modulus, Shear Modulus, Bulk Modulus and Poisson ratio is obtained from compressional and shear velocity measurement from the downhole wireline log. This gives a description of geomechanical parameters in the reservoir and caprock zones.
