1. An integrated process for in-field upgrading of hydrocarbons comprising:

  • passing a hydrocarbon feed into an in-field upgrader from a hydrocarbonaceous production source;

    mixing the hydrocarbon feed with a fluid comprising water that has been heated to a temperature higher than its critical temperature in a mixing zone to form a mixture;

    passing the mixture to a reaction zone;

    reacting the mixture in the reaction zone under supercritical water conditions in the absence of externally added hydrogen for a residence time sufficient to allow upgrading reactions to occur;

    withdrawing a single-phase reaction product from the reaction zone;

    recovering energy from said reaction product for use in the hydrocarbonaceous production source; and

    separating the cooled reaction product into gas, effluent water, converted hydrocarbons and unconverted hydrocarbons.
