Oil Field Ops Flashcards
Define Flashpoint
Temperature at which a flammable/combustible liquid will evaporate, mix with air and ignite
Define specific gravity
The weight of a liquid in relationship to water
Define vapor density
Weight of a gas in relationship to air
Define Vapor Pressure
Force exerted by evaporating liquids
Define Viscosity
The resistance to movement of a liquid
How deep are oil wells dug
3000-15000ft
What do oil wells produce
Gas (methane propane)
Crude oil (gas, diesel)
Salt water
What are the components of a drill
Mast (where drill goes up and down) Rig Base (typically two stories) Blow out protection (for emergencies) Power source Mud (lubrication for mast)
What is Field gas also known as and what is it
Also known as wet gas
It is gas (methane) before it has been separated from water and sent to refinery
What is Crude oil
Oil that has not gone to refinery yet
Is salt water a useful byproduct of drilling?
No its simply a byproduct
It has no market value and its recycled into the system
What are the two types of recovery methods
Primary and secondary
What is a primary recovery method also known as
A flowing well
There is enough pressure in the well to flow to the surface
Where does product go after it is recovered from a well
Trap farm
What happens in a trap farm
manifold assembly w/ several separators
Gas separators are upright so gas flows to rope since its lighter
Oil and water flow out of bottom to heater treater
BTU output of petroleum fires compared to regular fires
5x more BTU than regular fire
Where does field gas go once separated
Transported through piping to refinery
Who are the SME in mitigating oil field fires
Oil companies
What info is important to get at oil field fire
Part of the production process
Type of fire (vapor crude gasoline)
Mitigation actions
3 firefighting options at oil field fire
Fight fire
Exposures
Sit and wait
Most dangerous fires at oil field
Cellar Fire
Baker tank good to knows
Might not have water so check
Drafting operation
Up to 20,000 gallons of water
Hazards in oil fields
H2S Chlorine Hydrochloric Acid Hydrofluoric Acid Sulfuric Acid Formaldehyde
H2S characteristics in oil process
Found in all stages of oil process Odorless, colorless Heavier than air (low lying places) Corrosive to metals Ignite at 500 degrees Wide flammable range 4.3-46% Absorbed through inhalation 6x more toxic than CO Headache/diziness, nausea, RESP arrest
