文摘
- •
Chlorite-cemented facies has large creep strains when exposed to CO2 solution.
- •
Chlorite cemented facies failure envelope fails below in situ stresses.
- •
A lower-than in situ stresses yield with plastic strain caused by grain-contact weakening.
- •
Elastic moduli degradation onset closer to in situ stress than plastic strain onset.
- •
Chemical-weakening of chlorite facies may induce Cranfield DAS perm. changes.
