Get ready to put it all together! Please get your interactive notebook. Read the board. Laptop safely off your desk.
Brainstorm game! 60 seconds
Oil and gas formation
Coal, Oil and Natural Gas are fossil fuels
fossil fuels contain hydrocarbons with lots of bonds- more bonds to break = more energy
Interactive Notebook Title: Carbon Cycle Date: Jan 23 Fold and glue in Carbon cycle
Add to the Carbon Cycle notes:
Energy = The ability to do work Fuel = a substance which can be used to provide energy
Finding the oil3D seismic imaging is like an ultrasound
Drill to the oil, pump it out Primary oil recovery: oil flows into well because of gravity and pressure.
Spindletop – Beaumont 1903
Secondary recovery: hydrocarbons must be forced out by water (or gases like CO2) to maintain pressure in the system
Injection well Production
well
Horsehead pump
Tertiary recovery – a base like soap is added to water to move the last hydrocarbons
Base added
The current oil Boom!2005 – Fracking technology makes more reserves economically
viable2011 – current boom explodes with frackingUS crude output expected to crest around 9.5 million barrels per
day in 2016, then begin to decline in 2020. (7.5 million barrels/day projected through 2040)
Tradeoffs!
Quick check – put the following steps in order!
A. Shale rock fractures releasing petrochemicals B. Borehole drilled vertically past water table C. Natural gas and petroleum rises through well back to surface and is collected in tanks.
D. Propants keep fractures open and gas flowing E. Fracking fluids sent down well under pressure F. Horizontal drilling through shale layer
Check it! B, F, E, A, D, C
Distillation column at refinery
Purpose: to separate crude oil into different products based on length of hydrocarbon chains!
These must be on your flow map!
