Some features of natural reservoir in basis of the field White tiger (offshore of South Vietnam)

The rapid growth of hydrocarbon extraction and consumption sets up under specialists an urgent task of searching deposits with law-yield and compound structure of NR also in basis rocks bedded in oil and gas basins. Not all cracking selvages are permeable and it is necessary supplementary indications that help differentiate cracking selvages according to their permeability. All cracks before Miocene age (generated before oil migration) filled with second minerals and are impermeable. The practically important conclusion is that only examination of new cracking systems helps to forecast some parameters of effective porosity and geometry of oil saturated cracked reservoirs of basis. Since oil migrated to pore-cracked surroundings of White tiger reservoir rocks late so all geological processes and effects before Miocene don’t have influence on oil and gas accumulation and present no more than academic interest.
