Q. Hydro-dynamic trapping, Solubility trapping and Mineral trapping is related to which of the following?

[A] Carbon sequestration

[B] Coal mining

[C] Off shore drilling

[D] Mineral exploration measurements

Answer: A

In recent years, fundamental research has focused increasingly on the short- and long-term effects of CO2 injection into reservoirs to assess the feasibility of CO2 storage on a commercial scale.  

  • Sequestration processes involve different trapping mechanisms according to the hydrodynamic, physical and chemical conditions in the formation.  
  • It is common to divide these mechanisms into four different categories: hydrodynamic trapping, residual trapping, solubility trapping, and mineral trapping.
