  Several observables for the deeply virtual Compton scattering process have
been simulated in the kinematic regime of a proposed Electron-Ion Collider to
explore the possible impact of such measurements for the phenomenological
access of generalized parton distributions. In particular, emphasis is given to
the transverse distribution of sea quarks and gluons and how such measurements
can provide information on the angular momentum sum rule. The exact lepton
energy loss dependence for the unpolarized $t$-differential electroproduction
cross section, needed for a Rosenbluth separation, is also reported.
