Oil and Gas (Upstream, Midstream, and Downstream)
Mining Transport and Processing Refinery and Distribution
The oil and gas industry spans a complex chain of processes – from extraction to processing to distribution (Upstream, Midstream, Downstream). This industry places extremely high demands on measurement technology. Difficulties arise mainly from dealing with abrasive and corrosive substances, the necessity of explosion protection, ensuring functional safety, and coping with extreme pressure and temperature conditions. Instruments for process measurement must therefore not only provide precise measurement data but also exhibit high robustness and resistance to the challenging conditions.
As part of the pursuit of a low-carbon future by 2050, the industry continuously develops and optimizes new methods to reduce greenhouse gas emissions and other environmentally harmful emissions. This includes improving energy efficiency in all processing steps as well as refining the capture and control of operating parameters.
To support the industry in these challenges, a provider offers innovative solutions for measurement technology. These include instruments for pressure, temperature, level, and flow measurement, as well as force determination. They also involve strategies for minimizing and avoiding volatile emissions. In addition, the provider offers an extensive range of calibration tools and services, including calibration services, field service for temperature measurements, and repair of pressure transmitter systems. A subsidiary specializes in products and services for the safe handling of SF6 and other gases used in substations for powering refineries and offshore platforms.
▷ Promotion in the Oil and Gas Industry
Drilling
The beginning of the value chain in the oil and gas industry is characterized by the upstream process of drilling. This starts once a potential oil or gas reservoir has been located through exploration. Specialized industrial machinery is then used to penetrate through various geological layers to extract the desired crude oil or natural gas. The necessary technology for this includes various components such as the drilling rig itself, mud pumps for circulating drilling fluid, blowout preventers with associated closing devices in case of uncontrolled pressure increase, cementing units for stabilizing the wellbore, mud tanks, water tanks, and choke manifolds for pressure regulation.
This equipment must withstand extreme conditions: strong vibrations, pulsations, and high pressure ratios in deep drilling operations. Onshore, additional challenges arise from dust and fluctuating temperatures, while offshore facilities must also withstand the aggressive conditions of saltwater and spray. For all these demanding operating conditions, reliable and robust sensors are essential, capable of continuously and accurately providing measurement data to ensure the safety and efficiency of production processes.
Components
Drilling rigs vary greatly in size and are used both offshore and onshore. The range spans from mobile, transportable units to gigantic, stationary constructions that can rival skyscrapers in height. The core of each rig is the drilling table or alternatively a top-drive system, which rotates the drill string along with the drill bit at the bottom end. Regardless of dimensions, location, or type of rig, they all pursue the same goal: the exploration of deep-seated hydrocarbon deposits.
To operate such a rig safely and effectively, it is equipped with a variety of sensors. These include tension and pressure sensors, which operate even temperature-compensated in the wire rope bearings, to level and pressure gauges in the mud circulation systems. Furthermore, resistance thermometers are in use, based on thin-film technology, capable of withstanding the intense vibrations and pulsations to monitor the numerous pumps and motors.

During the process of deep hole drilling, the drill bit and the drill string drive through geological layers, while one or more high-pressure mud pumps inject drilling fluid into the depth of the borehole at extremely high pressure (more than 7,000 psi or 483 bar). This drilling fluid serves crucial purposes:
- It provides lubrication and cooling for the drill bit.
- It carries the cuttings generated during drilling out of the hole.
- It maintains pressure in the borehole to prevent fluid influx from the formation. Once the drilling fluid has served its purposes, it flows back to the surface through the annular space between the drill string and the borehole wall.
The mud pump consists of a drive part with a motor and a fluid part with connections. A robustly constructed “hammer union” pressure transmitter, corrosion-resistant, is combined with an intrinsically safe protection circuit to control the pressure on both the suction and discharge sides. A pressure gauge, equipped with a pressure equalizing system, indicates the pump pressure directly on-site. Additionally, in some pump systems, a pressure gauge is used to monitor the oil pressure responsible for lubricating bearings and seals.

When formation fluids, including easily ignitable hydrocarbons, uncontrollably flow out of a wellbore, it is referred to as a “blowout”. To prevent such a risky situation, Blowout Preventers (BOPs) and their closing systems are employed.
A BOP consists of a series of valves mounted on the wellbore, aiming to control and, if necessary, seal the wellbore during a so-called kick – the unexpected influx of fluids into the wellbore. Gauges, combined with intrinsically safe or explosion-proof pressure transmitters, form the core of this wellbore control system.
The closing mechanism of the BOP utilizes nitrogen bladder accumulator bottles, hydraulic oil, as well as electric and pneumatic pumps to generate pressure. This pressure is used to actuate various functions of the BOP. A network of gauges, pressure transmitters, and level sensors ensures that this crucial safety system can be reliably activated in case of emergency.

Cementing is a critical step in the drilling process. Once the target depth is reached, the drill string is removed and replaced with casing pipes. The primary purpose of primary cementing is to isolate different geological formations – such as oil, gas, and water-bearing zones – from the wellbore. This process also involves filling the space between the casing pipes and the wellbore, which stabilizes the pipes, prevents corrosion, and protects them from the pressure of the surrounding rock formation. Remedial cementing is performed to address any deficiencies in primary cementing, to correct or seal an already depleted wellbore.
The cementing unit required for this process is typically mounted on a skid or trailer. It draws water, dry cement, flushing fluid, and various additives from storage tanks. These components are mixed to form a “lead slurry” and “tail slurry,” which are then pumped into the casing and the surrounding annulus. The operator can adjust the flow rate and density of the cement slurries, control the pressure, and manage other important parameters using a control panel on the cementing unit. An essential instrument for pressure monitoring is the “hammer union” pressure transmitter, specifically designed for very high pressures and resistant to the abrasive effects of the cement mixture.

Spültanks sind umfangreiche Behältnisse, die in verschiedene Sektionen gegliedert sind und zur Aufbereitung, Vermischung und Lagerung der Bohrflüssigkeit dienen. Diese Flüssigkeit wird von der Spülpumpe sowohl in das Bohrloch geleitet als auch daraus extrahiert. Wenn die genutzte Bohrflüssigkeit zurück an die Oberfläche gelangt, durchläuft sie mehrere Bereiche im aktiven Tank:
- Einen Saugbereich, der als Vorfilterzone dient.
- Ein Feststoffkontrollsystem, das Bohrreste wie Gesteinssplitter und Sand entfernt.
- Einen Entgaser, der Luft und Erdgas aus der Flüssigkeit zieht.
- Einen Chemikalienbereich für eventuell notwendige zusätzliche Aufbereitung.
- Ein Rührsystem, um die Mischung wieder gleichmäßig zu vermengen.
Nach diesem Reinigungsprozess steht die Bohrflüssigkeit wieder zur Benutzung bereit. Zusätzliche Reservetanks halten Ersatzflüssigkeit sowie speziell schwere Schlämme für Notfallsituationen vor.
Durch den Einsatz von Füllstandssensoren können die Bediener den Flüssigkeitsstand in jedem Segment überwachen. Besonders wichtig ist dabei, dass Veränderungen im Füllstand auf potenzielle Probleme bei der Bohrung hinweisen können:
- Ein Anstieg deutet auf den Eintritt von Wasser oder Formationsflüssigkeiten (Öl, Gas) ins Bohrloch hin.
- Ein Rückgang signalisiert, dass die Bohrflüssigkeit in die umgebende Formation sickert.
Füllstandssensoren in Spültanks müssen den Anforderungen in explosionsgefährdeten Bereichen gerecht werden und gleichzeitig mechanisch robust sowie gegenüber den oft korrosiven, viskosen und abrasiven Eigenschaften der Bohrflüssigkeit widerstandsfähig sein. Obwohl verschiedene Arten von Füllstandssensoren genutzt werden können, bietet eine eigensichere Pegelsonde, die sowohl die Fluiddichte als auch den hydrostatischen Druck misst, eine besonders zuverlässige und wartungsarme Lösung. Der LevelGuardTM von WIKA bietet hierbei einen zusätzlichen Schutz gegen Verstopfung, Turbulenzen und mechanische Beschädigungen und gewährleistet so eine stabile Messung.

On a drilling site, the circulation pump uses a special fluid to lubricate and cool the drill bit during the drilling process, remove drill cuttings, and establish pressure balance to prevent fluid intrusion from the rock formation. This drilling fluid can be prepared either water-based or oil-based, depending on the nature of the geological formation, economic considerations, environmental requirements, the intended purpose of the flush, and other factors.
Water, in varying amounts, is almost always a significant component of the flushing fluid. It is stored in large tanks and then transferred to mixing tanks where it is blended with other components for the final flush.
To ensure that the water tanks at the drilling site neither overflow nor run dry, level probes are used. These probes accurately and reliably detect the fill level. WIKA’s LevelGuardTM provides additional stability to the pressure sensor and protects the measuring instruments from strong turbulence and mechanical stress.

Choke manifolds play a central role in the blowout control system of a drilling rig. In the event of a kick, the blowout preventer (BOP) is activated and shuts down the wellbore. Formation fluid and drilling mud escaping from the annulus are diverted into the system of pipes, connections, and valves of the manifold through the choke line. The purpose of the choke manifold is to regulate the flow rate of the lighter drilling mud to keep the pressure in the annulus below the maximum allowable surface pressure (MAASP). Simultaneously, heavier drilling fluid is pumped from a reserve tank into the wellbore to regain control of the situation. Operators can adjust the flow direction of fluids as needed by closing and opening valves in the choke manifold. Some chokes are manually operated, while others have hydraulic remote control.
Pressure measuring devices, including gauges and pressure transmitters, are installed at critical points of the system, including:
- where the choke line meets the manifold.
- at the outlets of the manifold diverting the fluids into a containment pit and/or a mud tank.
For the effectiveness and safety of pressure sensors on a choke manifold, the following characteristics are crucial:
- High measurement accuracy and fast response time.
- Resistance to corrosion and abrasion.
- Comprehensive protection against weather conditions.
- Certifications for use in hazardous areas.
