What is the definition of oil rim?
In petroleum engineering, an oil rim field is an oil field with a relatively thin oil zone below a gas cap. At the edges of the reservoir there will ususally be an area where the top of the reservoir is below the gas/oil contact, thus forming a "rim" containing only oil, with no overlying gas.
What is good permeability in oil reservoir rock?
Good permeability in oil reservoir rock refers to its ability to allow fluids to flow through it easily. This enables oil to be extracted more efficiently. High permeability is desirable as it allows for the movement of oil from the rock to the wellbore.
What replaces oil once it is removed from the ground?
After oil is removed from the ground, it can be replaced with water, natural gas, or steam to maintain pressure in the reservoir and continue extracting oil. Alternatively, the reservoir may be left to naturally produce oil through pressure differentials.
Describe two secondary recovery processes Why are such processes important?
Two secondary recovery processes are water flooding and gas injection. Water flooding involves injecting water into the reservoir to help displace oil towards the production wells. Gas injection, like CO2 or natural gas, helps maintain reservoir pressure and decrease oil viscosity for easier recovery. These processes are important as they can help recover additional oil that was left behind after primary recovery methods, ultimately increasing the overall oil production from a reservoir.
