now my friend, if you are not entirely sure of what's going in the commod trading market, then probably you shldn't comment.

to be a good physical (i reckon you meant oil) trader, you better make sure you start off with operations...and a good physical trader isn't just relationship building/biz development or old boys thing...oil scheduler?? the position is called operators, an oil scheduler is somebody that works for the refinery and out of every 20, only 1 will ever have the chance of being a trader...

there's a reason why physical traders are always more sought after than paper traders...let's put it simply a good physical trader can be a paper trader but a good paper trader can never be a good physical trader...

qte-
In commodities house like mitsui, glencore, noble, etc, usually paper trades (i.e. swaps, futures, options) are used in conjunction with physical for arbitrage, relative value, capturing contango effect, etc
Pure paper traders usually sit in investment banks. Goldman Sachs (J Aaron), JP Morgan, Morgan Stanley run desks here. They do mostly market-making, managing client flows earning bid-ask spread while running some basis risk.

Prospect is good if you are get in.
Physical trading tends to be more relationship building, business development type with well-establised old boy network.
Paper traders tend to be very well-educated quantitative type usually comes from ivy league, similar to financial derivatives trader.

To get into physical trading, most start off as oil scheduler i.e. someone who sorts out the logistic part of physical delivery of oil.
To get into paper trading, you should join management trainee program in GS, JPM or MS.
