A surge device providing a vent for bleeding pressure off an air drilled well and providing connectors for surge lines in the blooie line. The surge device has a hollow, abrasion resistant, tapered chamber into which two surge lines and the blow down line enter the surge device. The device is provided with a flange at each end of the chamber for attaching the device into a blooie line with the narrow end of the tapered chamber attached to the downstream end of the blooie line and an enlarged end of the tapered chamber attached to the upsteam end of the blooie line. An abrasion resistant shield pipe penetrating the enlarged end of the tapered chamber and extending into the tapered chamber a sufficient distance to serve as a shield for the terminal ends of the surge lines and the blow down line.
