Solutions for Oil and Gas Production Level, Multiphase Level and Density Measurement

BERTHOLD TECHNOLOGI BERTHOLD TECHNOLOGIES radiometric instruments are perfectly suited for use in the offshore and onshore oil industry. They are installed on Drilling Rigs, Production Platforms, FPSOs and Oil Terminals and provide highly accurate and repeatable readings, - the base for a profitable and safe operation. Regardless whether ■ a high level / low level alarm, ■ a continuous level measurement, ■ interface measurement or ■ a density measurement is needed - all of our detectors are characterized by an outstanding level of sensitivity and long-term stability -reducing radiation levels...

BERTHOLD TECHNOLOGI

The composition of drilling mud is an important factor because it ensures stable conditions in the wellbore. An online density measurement at the feeding line provides real-time information on the mud density before it enters the wellbore. A second density system at the mud returning line is used for the measurement of solid contents referring to the cuttings in the flow. In combination with a flow meter the mass flow of cuttings can be determined. Application Profile ■ Measurement task Density of drilling mud (Mass flow) ■ Location Mud feeding / mud returning line ■ BERTHOLD Solution Radiometric...

BERTHOLD TECHNOLOGI The reliable control of high level and low level set points is very important for process safety in the oil and gas production. Separators especially have such a safety system that prevents from overfilling and ensures operability of following processes. The BERTHOLD instruments used for level switch applications ensure the highest degree of safety and reliability. The system is mounted on the outer tank wall and therefore not exposed to the high pressure and high temperature conditions inside the tank. Existing tanks can be easily retrofitted by the BERTHOLD point level systems,...

During the separation process, the interface between oil and water has to be determined. A reliable control of this interface is very important because it prevents oil from entering the water outlet and ensures that water is not reaching the oil side. BERTHOLD interface measurements are used in horizontal and vertical separators ensuring maximum safety and reliability in the prevailing high pressure and high temperature processes. Application Profile ■ Measurement task Oil/ Water interface ■ Location Separator, Slug Catcher, Knock Out Drum ■ BERTHOLD Solution Radiometric level transmitter (SIL2...

Multiphase Level Measurement With the Multiphase Level Measurement system the level and the thickness of the different product from BERTHOLD the operator receives a live picture layers: oil, water, emulsion, sand, gas. It provides of the highly complex separation process taking real time values and a graphic display for trending place inside the tank. Continuously and over the in order to improve important control parameters whole measuring range the instrument measures like residence time and the addition of chemicals.

Ideal picture of the on-going separation process Level and thickness of all different layers Achievable accuracy ≤ 20mm level Improved addition of chemicals e.g. anti-foam agent, demulsifiers Ideal control of all outlets and inlet Highest operational safety (SIL2 option) Trend monitoring and data logging Easy to use Control Unit with HMI (graphic display, measurement values and alarms) Characteristics Several detectors are mounted outside the tank, while the radiation sources are inserted in a dip pipe. Each detector is used to measure the position of the interface layer in a very confined range...

BERTHOLD TECHNOLOGI Continuous level measurement with the source inserted in a dip pipe.

Measuring Sand Level Sand is removed from the liquids in hydrocylones or in sand settling tanks. The sand level information is very important to control the desanding process. BERTHOLD radiometric level transmitters are ideal for monitoring the sand level, because of their non-contacting nature. Depending on the individual application and requirements the measurement can be realized either with multiple point level measurements or with continuous level measurements. Measurement task Sand level measurement Location Separator, Sand settling tank, Desanding unit BERTHOLD Solution Radiometric level...

BERTHOLD TECHNOLOGI Wet Gas Scrubbers are used for the separation of mist and liquid droplets out from the gas stream. The liquids are collected in the bottom of the vessel and have to be measured by a reliable measuring system. BERTHOLD level measurement gauges are used to measure the total liquid level in a gas scrubber. Due to their high stability and repeatability the systems are maintenance-free and do not require re-calibrations. Application Profile ■ Measurement task Continuous level measurement of liquids ■ Location Wet Gas Scrubber ■ BERTHOLD Solution Radiometric level transmitter (SIL2...

Detecting Slugs Severe problems can be caused by slugs on offshore slugs are measured by means of radiometric den- platforms. Examples include disturbance in separa- sitometers with shortest response time to guaran- tors, excessive flaring and reduction of production tee an early warning and initiation of appropriate capacities. In order to reduce the adverse effects an early detection of an arriving slug is essential.
