Porous sandstone is a good reservoir rock for its porosity enables it to store the fluid (oil?) and also to allow easy release.
Compare with oil shale, where the rock is very fine grained and will not release the fluid easily.
Both would ideally be capped with an impermeable cap rock to constrain the oil.
The impermeable rock on top of a reservoir is called a cap rock. It acts as a barrier that prevents fluids from migrating out of the reservoir.
Source rock and reservoir rock both play essential roles in the formation and production of hydrocarbons in oil and gas fields. Source rock is the rock formation in which organic matter is deposited and transformed into hydrocarbons, while reservoir rock is the porous and permeable rock that stores and allows the flow of hydrocarbons. Together, they contribute to the accumulation and extraction of oil and gas resources.

To have a petroleum resource, you need a source rock rich in organic material (such as algae or plankton), a reservoir rock with high porosity and permeability (like sandstone or limestone), and a seal rock above the reservoir to prevent oil and gas from escaping. Additionally, the presence of traps, such as anticlines or faults, is essential for the accumulation of oil and gas.
The physical characteristics of reservoir rocks that enable them to store fluids and to allow fluids to flow through them. The main properties of interest are rock porosities and permeabilities.

Reservoir wettability refers to how easily fluids (such as oil and water) can flow through the pore spaces of a reservoir rock. It is a measure of the rock's affinity for different fluids, affecting the movement and distribution of fluids in the reservoir. Understanding reservoir wettability is crucial for optimizing oil recovery strategies.

It is a reservoir near Branson, MO.

There are two types of migration when discussing the movement of petroleum, primary and secondary. Primary migration refers to the movement of hydrocarbons from source rock into reservoir rock and it is this type that the following discussion refers to. Secondary migration refers to the subsequent movement of hydrocarbons within reservoir rock; the oil and gas has left the source rock and has entered the reservoir rock. This occurs when petroleum is clearly identifiable as crude oil and gas although the gas may be dissolved in the oil. Buoyancy of the hydrocarbons occurs because of differences in densities of respective fluids and in response to differential pressures in reservoir rock.
The displacement efficiency refers to the fraction of the oil in place that is swept from a unit volume of the reservoir. Displacement efficiency is a function of fluid viscosities and the relative permeability characteristics of the reservoir rock (mobility ratio), of the “wettability” of the rock, and of pore geometry.
