Rock properties

What is a reservoir rock?

• Composed of various hydrocarbon components with wide-ranging properties

• A natural or artificial place where water is collected and stored for use,

• An industrial installation where crude oil is refined to produce fuels including petrol, paraffin, and diesel oil.

•  A permeable subsurface rock that contains petroleum. Must be both porous and permeable

The three sedimentary rock types most frequently encountered in oil fields are...

• Shale

• Granite

• Carbonates

• Sandstone

There are four fundamentals of sedimentary rocks EXCEPT

• Grains

• Cement

• Porosity

• Density

• Matrix

A  good  reservoir  rock  must  have  _______ in which petroleum can exist

• permeability

• porosity

• wettability

• pressure

Porosity can be classified into TWO categories. Which are...

• original porosity

• blank porosity

• induced porosity

• additional porosity

Permeability is a property of the porous medium that measures the ability of the formation to......

• transfer the fluids

• stop the fluids

• transmit the fluids

• measure the fluids

Methods for determination of reservoir fluid saturations are

• direct measurement

• indirect measurement

• real measurement

• true measurement

The tendency of a fluid to spread on or adhere to a solid surface in the presence of other immiscible fluid

• Surface tension

• Permeability

• Wettability

• Porosity

When the interface is between two liquids, the acting forces is called

• wettability

• surface tension

• permeability

• interfacial tension

When two liquids come into contact and they do not mix, they are called?

• unsaturate

• miscible

• saturate

• immiscible
