Narrative:

Air carrier X, a slc departure to ocs J94 climbing to FL290. Military Y, an en route aircraft slc-ocs at FL290. I had stopped X at FL290 for traffic on J94 at FL330. X was overtaking and converging with military Y at ocs. I turned X to a heading of 020 degrees to go behind Y. When X was approximately 15 mi north of ocs VORTAC, I cleared the aircraft direct FOD J94 and climbed X to FL330. At this time Y was over ocs VORTAC but his beacon had momentarily disappeared. When the beacon reappeared I observed aircraft in a left turn (north) instead ocs-bff, the routing I thought the aircraft was flying. As soon as I observed the turn, I gave X a 010 degree heading, no immediate response. I then gave Y a turn to 080 degrees, no immediate response, then a 090 degree heading which Y responded to. I then told X to expedite to FL310. I had looked at Y's strip and had established in my mind the aircraft was remaining on an eastbound route: ocs-bff not the actual route ocs-boy (north). A more timely response from both aircraft could have aided in alleviating the situation. Loss of Y's target was a problem also.

Original NASA ASRS Text

Title: ACR X CLB THROUGH OCCUPIED ALT HAD LTSS FROM MIL Y. SYS ERROR.

Narrative: ACR X, A SLC DEP TO OCS J94 CLBING TO FL290. MIL Y, AN ENRTE ACFT SLC-OCS AT FL290. I HAD STOPPED X AT FL290 FOR TFC ON J94 AT FL330. X WAS OVERTAKING AND CONVERGING WITH MIL Y AT OCS. I TURNED X TO A HDG OF 020 DEGS TO GO BEHIND Y. WHEN X WAS APPROX 15 MI N OF OCS VORTAC, I CLRED THE ACFT DIRECT FOD J94 AND CLBED X TO FL330. AT THIS TIME Y WAS OVER OCS VORTAC BUT HIS BEACON HAD MOMENTARILY DISAPPEARED. WHEN THE BEACON REAPPEARED I OBSERVED ACFT IN A L TURN (N) INSTEAD OCS-BFF, THE ROUTING I THOUGHT THE ACFT WAS FLYING. AS SOON AS I OBSERVED THE TURN, I GAVE X A 010 DEG HDG, NO IMMEDIATE RESPONSE. I THEN GAVE Y A TURN TO 080 DEGS, NO IMMEDIATE RESPONSE, THEN A 090 DEG HDG WHICH Y RESPONDED TO. I THEN TOLD X TO EXPEDITE TO FL310. I HAD LOOKED AT Y'S STRIP AND HAD ESTABLISHED IN MY MIND THE ACFT WAS REMAINING ON AN EBOUND RTE: OCS-BFF NOT THE ACTUAL RTE OCS-BOY (N). A MORE TIMELY RESPONSE FROM BOTH ACFT COULD HAVE AIDED IN ALLEVIATING THE SIT. LOSS OF Y'S TARGET WAS A PROB ALSO.
