A control system for wild oil and gas wells etc. using a centered, angled tubular device placed over and attached to the well head by clamps and remotely controlled hydraulic cylinders. The discharge of the well is directed into the bottom of the device, having movable blades forming two apertures used to minimize the induction of air from the exterior. Inert gas from engines powering pumps is injected into the space between the apertures, so that greater than atmospheric pressure in this chamber will result in the outflow of inert gas and prevent induction of air. Inert gas can also be injected into the main body of the device when required to prevent combustion. High pressure motive fluid is discharged from nozzles within the angled chamber of the device, directing the oil and liquids which impinge on the upper surface of the tube to be directed by baffles to its bottom, then flowing into a collecting trough and drawn through slots in the trough bottom by fluid jet eductors. The collected discharge is then directed up a separate tube by jets adding velocity head to the stream, causing it to flow down the length of the device to a remote separator for disposal or storage. The well gas is directed up the tube by high pressure fluid discharged through nozzles providing a fan shaped spray to impart an initial velocity to the gas.
