Go downstream bro working for operator or client (petronas/ shell/ Exxon Mobil). Its still more stable as they would prefer cheaper local people compared to previously it was vast experience expat. Upstream would still be operating eventhough the oil n gas price are low.

Dont go for upstream as the oil price goes down, the exploration and drilling activity goes down. Only left people that know how to do the job and more cheaper than usual offshore worker.
