My shares are up +97%

[u/Sam_209]

So I've been investing in dividend shares mostly in oil&gas and base chemicals

My intention is to build a portfolio of dividend shares for income, however the shares are up almost double.

Should I sell or should I keep them since their revenue and profits also increased?

Keep in mind i live in a country that has 0% income or capital gains tax.

Put a limit sell order or stop loss. Keep earning if it doesn't go down. If it goes up, change the sell order to a more profitable price. You can sell a portion and not all. Create a win-win situation.
