Safe monitoring of the integrity of oil and gas wells
Increased efficiency and system transparency
Monitoring well integrity on a scheduled basis is becoming increasingly challenging for oil and gas well operators in times of skilled labour shortages and increasing regulatory requirements. Since wells are often located in remote areas, teams of trained experts must drive to these sites, which can pose risks for the personnel. On-site, the annulus and tubing pressure is read, analysed and manually documented. This labour-intensive process only provides a snapshot of the condition, ties up valuable resources and makes operations and maintenance costly. With the WIKA IIoT solutions, relevant measuring locations can be digitally recorded using wireless sensors without laying a single cable.
This increases system visibility to more than 99 %. For documentation, no values need to be read on-site, documented and transferred into a system, reducing physical inspections by over 75 %. In the event of an integrity-relevant event, the intelligent WIKA IIoT device sends an alarm to the platform. The responsible technician is directly informed and can monitor the history and condition of the well from the control room, take appropriate actions and respond quickly.

Application and platform
WIKA provides a universal and autonomous integrity monitoring solution for remote access to oil and gas wells. It includes an automated documentation, condition visualisation, anomaly detection with simplified alert management for fast response in case of integrity events. The exchange of data into proprietary systems is easily possible. Please request a live demo for more details.
What does well integrity mean in the oil and gas industry?
Well integrity describes the permanent intactness of wells over the entire production and life cycle. This includes hydraulic leak tightness to prevent uncontrolled material or pressure movement between the well, geological layers and the surface. Ensuring well integrity is crucial for safe oil and gas extraction, the use of geothermal energy and the protection of groundwater and drinking water. It requires both high-quality measures in the drilling process and continuous integrity monitoring during operation.
What are the key aspects of well integrality?
The central aspects include:
- Drilling technology and engineering (casing, tubing, cementation)
- Barrier proof (e. g. pressure/Leak tests, CBL, functional proof)
- Pressure monitoring in near real time (annulus/tubing pressure)
- Mechanical and hydraulic barriers
- Reporting and documentation
- Regular measurements and condition analyses
- Specified processes to ensure integrity across all operating phases
How is well integrity ensured?
It is ensured by a combination of the following factors:
- Remote monitoring of critical measuring locations
- Early detection of abnormalities
- Clearly defined alarm limits
- Reduced on-site inspections
- And also the use of intelligent, digital systems for efficiency, transparency and risk minimisation
Modern IIoT solutions such as those from WIKA enable automated, wireless and scalable monitoring, allowing operators to reliably guarantee the integrity of their wells, even in remote areas.
