1.
The thermal conductivity of salt is higher than that of basalt.
a)
True
b)
False
2.
From which geological phenomena can geothermal energy be obtained? (select all that applies)
a)
Hot springs
b)
Salt domes
c)
Volcanic activity
d)
Proximity to a glacier (through heat pump)
3.
What does "low enthalpy geothermal energy" mean?
a)
Low-enthalpy geothermal energy is a type of sustainable energy that leverages the Earth’s natural heat to generate power. Unlike high-enthalpy geothermal energy, which relies on high temperatures found deep underground, this geothermal energy captures the relatively lower-temperature thermal energy located close to the surface of the Earth.
b)
Enthalpy is the measurement of energy in a thermodynamic system. The quantity of enthalpy equals to the total content of heat of a system, equivalent to the system's internal energy plus the product of volume and pressure.
4.
What is the Curie Point in the geothermal context?
a)
It is the depth at which the temperature reaches 580 degC and where the rock undergoes a sharp change (drop) in its magnetic properties.
b)
It is the depth at which the temperature reaches 680 degC and where the rock undergoes a sharp change (drop) in its magnetic properties.
c)
It is the depth at which the temperature reaches 680 degC and where the rock undergoes a sharp change (drop) in its elastic properties.
5.
In high enthalpy systems, the alteration of clays into smectite leads to
a)
high conductivity layers that can be picked up by magneto-telluric surveys
b)
high conductivity layers that can be picked up by gravity surveys
c)
low conductivity layers that can be picked up by magneto-telluric surveys
6.
In geothermal systems, sources of heat can be (select all that applies):
a)
volcanic (magma, lava)
b)
non volcanic (radioactive decay in granite)
c)
meteoric
7.
Are magneto-telluric (MT) surveys deep or shallow? Are time-domain electromagnetic (TEM) surveys deep or shallow?
a)
MT=deep, TEM=shallow
b)
MT=shallow, TEM=shallow
c)
MT=deep, TEM=deep
8.
ORC stands for
a)
organic Rankine cycle
b)
original Rankine cycle
c)
organic rutile cycle
9.
Ambient air temperature has a direct impact on geothermal plants efficiency.
a)
False
b)
True
10.
Evaluating geothermal wells with logging-while-drilling has the advantage of decreasing the maximum temperature the tools are experiencing through:
a)
Cool mud circulation around the tools
b)
Thick LWD tools collar
c)
Drill-pipe conveyance
11.
Where was the first geothermal plant installed in Europe?
a)
Larderello
b)
Kizildere
c)
Ghirardelli
