A throttling valve formed by introducing an elongate tubular body into a tubular member through which fluid is flowing. The tubular body is provided with first and second ends, the first end being adapted for engaging a flow control device and the second end having a beveled end that enables fluid communication between the tubular member and the tubular body. The tubular body is provided with a tapered stem, the outside diameter of the stem proximate the first end of the tubular body being greater than the outside diameter of the stem proximate the second end, for seating against the opening in the end of the tubular member and effecting a seal between the outside surface of the stem and the margin of the opening in the tubular member. An elastomeric or other seal may be mounted on the outside surface of the stem for this same purpose.

The present invention provides system, method and apparatus for creating an electric glow discharge that includes a first and second electrically conductive screens having substantially equidistant a gap between them, one or more insulators attached to the electrically conductive screens, and a non-conductive granular material disposed within the gap. The electric glow discharge is created whenever: (a) the first electrically conductive screen is connected to an electrical power source such that it is a cathode, the second electrically conductive screen is connected to the electrical power supply such that it is an anode, and the electrically conductive fluid is introduced into the gap, or (b) both electrically conductive screens are connected to the electrical power supply such they are the cathode, and the electrically conductive fluid is introduced between both electrically conductive screens and an external anode connected to the electrical power supply.

In one embodiment, a method for preventing flaring at a facility, by a system, includes receiving a plurality of pressure measurements from a sensor disposed downstream of the facility. The method further includes comparing the plurality of pressure measurements to a threshold pressure, wherein the threshold pressure corresponds to mitigating a flaring event. In response to determining that at least one of the plurality of pressure measurements is greater than the threshold pressure, the method further includes analyzing injection response curves for a plurality of wells to determine a first well for adjusting a back pressure on a reservoir intersected by the first well. The method further includes transmitting an instruction to the first well to adjust the back pressure on the reservoir.
