The system will then gauge the oil concentration based on a light intensity meter. Modern oil content meters also have a data logging system that can store oil concentration measurements for more than 18 months. [2] Oil content meter. If the OCM determines that there is far too much of a type of oil, the OCM may be fouled and needs to be ...
A typical Master Control Station. On the top-side facilities of offshore oil and gas platforms, the Master Control Station (MCS) is a dedicated system that controls and retrieves data from subsea equipment on the ocean floor. The MCS is supplied by the manufacturers of the subsea control modules (SCM), an MCS is required for each vendor.
Instrumentation controls the operation of process columns. Instrumentation is used to monitor and control the process plant in the oil, gas and petrochemical industries. . Instrumentation ensures that the plant operates within defined parameters to produce materials of consistent quality and within the required specifica
Secondary oil well control is done after the Primary oil well control has failed to prevent formation fluids from entering the wellbore. This process uses "blow out preventer", a BOP, to prevent the escape of wellbore fluids from the well. As the rams and choke of the BOP remain closed, a pressure built up test is carried out and a kill mud ...
Functionality may be extended further by using the control system on a subsea tree to monitor, measure, and react to sensor outputs on the tree or even down the well bore. The control system attached to the tree controls the downhole safety valve (SCSSV, DHSV, SSSV) while the tree acts as an attachment and conduit means of the control system to ...
If the oil content is higher than 15 ppm, the OCM will activate an alarm and move a three-way valve that, within a short period of time, will recirculate the overboard discharge water to a tank on the OWS suction side. [4] An OCM takes a trickle sample from the OWS overboard discharge line and shines a light through the sample to an optical sensor.

Well control is the technique used in oil and gas operations such as drilling, well workover and well completion for maintaining the hydrostatic pressure and formation pressure to prevent the influx of formation fluids into the wellbore.
