Downhole Sensors Tools and Corrosion Monitoring :
Application
Rare earth magnets are used in various downhole sensors and measurement tools, including pressure and temperature sensors, flow meters, and casing inspections, to ensure accurate data collection and monitoring. Corrosion monitoring tools are used to detect and monitor the presence of corrosion or metal loss within pipelines and equipment, helping to prevent leaks and failures. Inspecting and maintaining the integrity of a pipeline and storage tanks is a fundamental requirement of any upstream, midstream, and downstream O & G operations.
Solution
Allstar specializes in the manufacture of Pipeline Inspection Gauges (PIG’s), Magnetic Flux Leakage MFL tools and Pipeline Pigs. They have the capability to customize sets of magnets to create the magnetic fields needed for the detection of corrosion and metals loss in pipelines. These same customized fields are also required in PIG’s to detect pressure, temperature and other critical performance indicators of a pipeline system.
Casing Collar Locators (CCL) :
Application
CCL is a magnetic downhole device that is used to detect changes in metal thickness to confirm or correlate treatment depth using known reference points on the casing string. It is mainly used for depth control and depth correlation.
Solution
Allstar understands how to create the magnetic field to optimize the sensitivity and accuracy of the CCL magnetic assemblies. They supply both the magnets and coils needed for CCL tools and can provide a custom turnkey solution for your needs.
Wellbore Stability and Magnetic Separation tools:
Application
These application rely on the uniformity of rare earth magnets in harsh environments. Magnets are used to stabilize wellbores by controlling the movement of metallic debris and particles, preventing them from interfering with drilling operations or causing wellbore instability. Magnetic separators are used to remove ferrous contaminants from drilling fluids and oil and gas production streams. This helps improve the quality of the extracted fluids and prevents damage to downstream equipment.
Solution
Allstar supplies various magnets and assemblies used for wellbore cleanout and filtration tools. An important consideration when assembling and producing these components is the ability to create and measure custom fields. The strength of these fields directly impacts the performance and effectiveness of the tools which reduce maintenance cost and avoid abrasion damage to critical components.
Submersible Pumps :
Application
Electric submersible pumps (ESPs): ESPs are used to generate the magnetic fields necessary for efficient and reliable motor operation. These pumps are commonly used for lifting oil and water from deep wells.
Solution
A major component for the systems is the Permanent Magnet Motor (PMM). Rare earth magnets are used in the rotor section both for their stability and reliability in challenging environments. Allstar manufactures efficient and cost competitive custom PM rotors.
Magnetic Survey Tools:
Magnetic survey tools help geologists and exploration companies locate and map underground magnetic anomalies. These tools are crucial for identifying potential drilling locations.
Allstar Magnetics supplies various magnets for geophones and downhole seismic data acquisition. see Geospace Technologies and Probe Technologies.
Not downhole, but see magnets used for these guys for vibration monitoring.
