IDK about gas, but the price cap on Russian oil is lower than what Russians need to break even. They are now losing money on each exported barrel, but IIRC they can't just stop the production; the wells would become unusable.
Of course, the price cap is only in force since December 2022, so the effects haven't fully shown themselves yet.
Where do you get that information about profitability? According to BBC [0] back in 2019 expenses per barrel was $25 before taxes. Obviously sanctions make everything more expensive (hardware, extraction, transport, insurance), but not that expensive.
If selling oil was unprofitable Putun would just burn it instead of selling it at loss just like they burned natural gas for $10,000,000 / day for months.
