A Pad\'e approximation approach, rooted in an infrared moment technique, isemployed to provide mass estimates for various glueball states in pure gaugetheories. The main input in this analysis are theoretically well-motivated fitsto lattice gluon propagator data, which are by now available for both SU(2) andSU(3) in 3 and 4 space-time dimensions. We construct appropriate gaugeinvariant and Lorentz covariant operators in the (pseudo)scalar and(pseudo)tensor sector. Our estimates compare reasonably well with a variety oflattice sources directly aimed at extracting glueball masses.
