Any way to get into labor jobs like construction or oil fields with no experience?

The title is pretty self explanatory. I'm a 19 year old male with no experience in any of these fields. But I want to get into it because I know earning potential is good. The job I have right now just isn't cutting it. Making 350 a week is not enough. Any tips? I live in Houston Tx btw, in the Richmond/sugarland/katy area
