The measurements of deeply virtual exclusive electroproduction processes are used to access and constrain the Generalized Parton Distributions from experimental observables. Among these exclusive reactions, deeply virtual meson production (DVMP) channels can be used to access chiral-even and chiral-odd GPDs which contain information about correlations between quark longitudinal momentum and transverse spatial distributions. Additionally, the variety of DVMP channels allows to perform the flavor decomposition of the underlying GPDs. The experimental measurements using 10.6 GeV incident electron beam and the CLAS12 spectrometer at Jefferson Lab focus on the forward regime ($t/Q^2\ll1$) with a wide kinematic coverage of $x_B$ in the valence regime and the photon virtualities $Q^2$ extending up to 8 GeV$^2$. We will also discuss the study of DVMP channels with upgraded electron beam energy to 24 GeV, and their analysis in terms of Generalized Parton Distributions.
