In a Petroleum Reservoir, Can we approximate an Oil-Water system to have the effective density of water but with the compressibility of oil? If so, when does the source of error get accumulated?
Well,
The movement of oil and its separation from the water accompanying it upon arrival at the reservoir is considered a kind of migration as well as the separation of gas from oil and water is considered as an internal migration.
This separation is under the influence of gravitational effects, weight and density .
There are several factors that control the migration of hydrocarbons (oil and gas).
1.Static pressures and hydrodynamic motion
2. Hydraulic Impact
3. Gravitational effects and Capillary action
5 - the effect of compression in changing the size of pores. (Porosity and compaction effects)
Static pressures and hydrodynamic motion
The pressure factor is one of the most important factors of the movement and migration of oil, whether vertical or horizontal because the oil accumulates in the source rocks, which are under the influence of the ever-increasing pressure of sedimentation.
