We analyze the role of indirect quantum measurements in work extraction fromquantum systems in nonequilibrium states. In particular, we focus on the workthat can be obtained by exploiting the correlations shared between the systemof interest and an additional ancilla, where measurement backaction introducesa nontrivial thermodynamic tradeoff. We present optimal state-dependentprotocols for extracting work from both classical and quantum correlations, thelatter being measured by discord. We show that, while the work content ofclassical correlations can be fully extracted by performing local operations onthe system of interest, the amount of work related to quantum discord requiresa specific driving protocol that includes interaction between system andancilla.
