What are you studying if you don't mind my asking?
The translation to English is earth sciences. But the English definition is too broad.
The Swedish definition is "geoscience".
The general topics I can think of in geoscience are:
1. The earth crust and inner coreThis includes topics such as Geophysics, Sedimentology, seismology etc.
Petrology is a subbranch of mineralogy which is a subbranch of geology, and petrology is obviously something I have an interest in and want to master in.2. Landforms and land processesThis includes topics such as Sedimentology, Geomorphology, Tectonics?
4. KryosphereIncludes Glaciology which is my second choice for master.
5. HydrosphereThis includes topics such as Hydrology, Oceanography.
6. AthmosphereThis includes topics such as Meteorology, Climatology.

Peak oil is a theory which sets critical dates that has to be postponed all the time so petrology is not a dying subject. They just recently found huge natural gas deposits in the eastern Mediterranean and major oil deposits outside Brazil and an unknown quantity outside the Falkland islands.
There is a big anticipation of huge unfound oil deposits around Greenland. And an anticipation of enormous oil/gas deposits in the arctic.
I have no idea about the antarctic but biomass was thriwing there until 15 million years ago when the most recent ice age era appeared. There might be oil there as well since oil is biological in origin.
Natural gas/hydrocarbon gas is more intriguing for me. It can be older and found deeper and its origins might in some cases have an alternative explanation to oil. I dare theorize that much hydrocarbon gas is ubiquitous and accumulated/filtered very deep in rocks as remnants of material that are not of earth origin as our solar system is packed with the necessary elements that hydrocarbons/oil/gas are composed of (think of Titan). And it can be cheaper to extract if it is pressurized enough. Hydrocarbon gas can be liquefied for example and is complementary to oil and a possible replacement if "peak oil" occurs. "Peak gas" might be so far off its not a relevant word to coin.
There are also ongoing scientific experiments to create synthetic oil. It is quite simple actually. Imagine brewers yeast producing ethanol from sugars. Bio engineered yeast could produce a whole spectrum of petrochemicals in structures that are like gigantic pot stills.
There are also conspiracy theories (I don't beleive in them) that oil is much more abundant than we are let believe as the value of the dollar is heavily tied to oil prices, the so called petrodollar that makes the dollar the world reserve currency. Once oil dries up the petrodollar drops in value and a tactic to uphold the dollar value would be to find some of these "secret" fields and licencese them out to the big oil companies as political favors from government. (As mentioned, this is only conspiracy theories, but we are in the internet age and feed of all possible trash information).
