E E] 7 F] F Hydrocarbon migrates from the matured portion of source rocks if: a) Capillary pressure is more than bouncy pressure. b) Capillary pressure is equal to bouncy pressure. c) Capillary pressure is less than bouncy pressure. d) Microfractures are developed. Density logs present the bulk density of a rock; density may decrease a) As a result of increasing the mineral's specific gravity. b) As a result of increasing porosity. c) As a result of increasing the fluid salinity. d) As a result of decreasing the fluid salinity. Porosity reduction may develop by cementation: a) Along and below sequence boundary. b) Along transgressive and maximum flooding surfaces. c) Along transgressive surface. d) Along maximum flooding surface. G]
B] Porosity enhancement along and below subaerial erosion surfaces (unconformity) may develop by: a) Dissolution of chemical unstable detrital grain and/or cement. b) Cementation of factures. c) Dissolution of chemical stable detrital grain and/or cement. d) Compaction of physically unstable detrital grains.
d) - All of the above. ] In TTI technique, the rate of maturation increases by a factor of (?) for each 10 °C interval. a) 2 (double). b) 3 (3 times) e) 4 (4 times) d) Zero "options that should be taken in consi
Dj Tar mat is important to identify and understand because: (a) It impedes the flow of water into a reservoir when petroleum is produced. b) It acts as a seal for hydrocarbon accumulation. c) All of the above, d) None of the above.
