The monitoring system is connectable to a sample point for receiving a sample of the well stream. The sample receiving system includes a fluid conduit connectable for fluid communication with the sample point, and a separator for separating a water fraction from the sample. The sample preparation system includes a filter for filtering the water fraction. The analyzing system includes an x-ray fluorescence analyzer for measurement of a concentration of at least one of dissolved elements Fe, Ba, Ca, S, Cl, P, Cu, Zn, Pb, Br or scale inhibitor tracers in the sample. The pressure control and measurement system is connected to the sample receiving system or the sample preparation system.

Abstract: A gas trap includes a sample enclosure, a bubbler enclosure, an agitator, and a brushless, DC motor. The sample enclosure has a liquid inlet, a gas sample outlet, and a sample enclosure wall with a sample enclosure wall portion and a shared wall portion. The bubbler enclosure has a bubbler air inlet, a bubbler air outlet, and a bubbler enclosure wall with a bubbler enclosure wall portion and the shared wall portion. The sample and bubbler enclosures are fluidly coupled through the shared wall portion so that sufficiently pressurized bubbler air entering through the bubbler air inlet maintains the drilling fluid in the sample enclosure at a level determined by the location of the bubbler air outlet when the liquid inlet and the bubbler air outlet are both submerged in the drilling fluid.

Abstract: A sampling system and a method for sampling fluid from a target zone within a well bore without commingling fluid from other zones in the well. The sampling system includes a hydraulic flow control system and a differential flow logging system. The hydraulic flow control system has a plurality of multi-level, vertically disposed pumps with fluid extraction rates set to generate hydraulic zones above and below a center one of the pumps. The hydraulic zones isolate fluid flow in a target zone surrounding the center pump, and the center pump collects a sample from the isolated target zone without mixing fluid from other zones of the well. The differential logging system has a plurality of flow devices. Each of the plurality of flow devices is disposed near one of the hydraulic zones to monitor vertical flow in the well and confirm isolation of the target zone.
