Measuring Instrumentation for Oil and Gas
Endress+Hauser has been providing instrumentation to the oil and gas industry for over 20 years. Working from end-user feedback, we have developed technological solutions to the problems that are encountered when accurate process measurement is required.
Endress+Hauser has produced the most varied range of instrumentation to match the needs of today’s oil and gas industry, examples include high static pressure transmitters and the replacement of conventional displacer devices with high accuracy radar level measurement.
BULK SOLIDS STORAGE
Time of flight devices such as Levelflex or the Soliphant vibrating tuning fork, provide accurate level measurement in bulk storage tanks containing barytes. Both techniques are particularly suited to the filling process, as they are unaffected by dust and are easy to install since they can be pre-calibrated.
MUD PIT LEVEL AND DENSITY MEASUREMENTS
Endress+Hauser’s ultrasonic instrumentation, Prosonic T and Nivosonic, and Micropilot Radar devices are particularly suitable for level measurements in the mud pit room.
Where required, our Liquiphant vibrating limit switches are ideal for high and low level alarm functions; they are immune to build-up, SIL 2/3 certified, and are extremely cost-effective.
MUD PUMPS – FLOW RATE MEASUREMENT
Endress+Hauser’s PROline Promass range of Coriolis mass flowmeters monitor the flow rate of the mud pumped from the pit to the drill and are designed to cope with high pressures. These multivariable devices provide direct mass and volume flow measurement, as well as density and temperature measurement.
For the measurement of pump pressure on the downhole pump set or in the cutting re-injection skid, Cerabar S and Deltabar S provide an ideal solution due to their high static pressure resistance, with the added benefit of simple commissioning.
SEPARATOR VESSELS – OIL, GAS AND WATER FLOW MEASUREMENT
Totally non-contact, Micropilot offers simple commissioning and easy set-up via its 4-line display and comes complete with a ToF-Tool operating programme, which facilitates extensive analysis functions.
Monitoring oil and gas flow is important and our Promass 64, 80 and 83 Coriolis mass flowmeters are ideal, withstanding pressures of up to 350 bar. To monitor water flow, Promag electromagnetic flowmeters are also easily applied. For pressures up to 250 bar, our Prowirl range of vortex shedding meters or the ultrasonic Prosonic Flow range should be used, which have been designed for high pressure applications.
FLOWMETERS FOR CHEMICAL INJECTION
Our Promass 80 and 83 range of mass flowmeters are ideally suited to the chemical injection phase, due to the low flow rates experienced. The versatile Promass range can monitor from as little as 0.1kg per hour, up to 800,000kg per hour and is simple to install and maintenance-free.
he two-wire Micropilot can be used for continuous monitoring of liquids, as well as for high and low alarms. Additionally, capacitance level measurement can be provided for separator vessel interface monitoring, storage/holding tanks and high/low alarms.
For more complete level measurement our Kontilot Gamma can be applied in low or high temperature separators, oil-water separators and flare knock out drums etc. providing high and low level, continuous measurement and interface as well as density profiling.
FLARE KNOCK OUT DRUMS
Liquid gas is stored in a flare knock out drum prior to being piped up and burned off. For this purpose, radar or gamma level instrumentation is ideal as both are simple to commission and maintenance free.
Mounted in a flare knock out drum, Micropilot continuously monitors the level without touching the liquid gas, avoiding the problems of build-up. Non-invasive, radiometric gamma devices go one step further – Gammasilometer and Gammapilot are mounted outside of the vessel wall, offering low cost of ownership. They are easily accessible, uninfluenced by process conditions and are an extremely efficient, maintenance-free level solution.
We offer thermowells with DNV type approval for both flashed and hub type connections. Our standard thermowells cover all pressure classes, both ANSI and API, up to 15,000psi, including some sub-sea applications.
Endress+Hauser’s Cerabar S and Deltabar S pressure instrumentation ensure the safe running of a platform through providing reliable pressure data from condensate export pumps, water injection pumps, gas turbines and sea water lift pumps for well head pressure indication.
Modular design ensures sensor modules, electronics, housings and display units can be quickly interchanged without the need for re-calibration.
