Barkley struck the post with a penalty from wide right and the rebound fell to the Worcester defence and Satala so nearly forced his way over but was gang tackled into touch at the corner flag.
The Cherry and Whites seemed to spend the whole of the last ten minutes hammering away in the Worcester 22 but not a tackle was missed.
Olly Morgan came closest, tackled just short of the line. His attempted offload hit the ground and Gloucester's hopes ebbed away.
