Find-Block®
Accurate pipeline blockage location, mobilized globally within 24 hours
Overview
A Find-Block® survey is the bedrock on which successful pipeline blockage remediation campaigns are built.
Armed with little more than a briefcase, Paradigm Engineers can be mobilized globally as quickly as within 24 hours to accurately locate stuck PIGs and full-bore flow assurance blockages to an accuracy of up to 1m/km – far more accurately than estimations made using pressure & volume data.
Find-Block® involves the recording and analysis of the pressure wave that is created during a quick, controlled bleed-off of pipeline pressure. The correlation of the known wave-speed in the fluid medium and the time taken to receive the reflection at the pipeline tie-in enables the distance to the obstruction to be calculated.
For an ever-growing global customer base, Paradigm’s Find-Block® is the first choice when it comes to locating blockages, both offshore and on land, allowing rapid decisions to be made for successful and effective blockage remediation. An evaluation of the suitability of our Pipe-Pulse® and Flexi-Coil® technologies for remediation is also undertaken during every survey.
Applications
Find-Block® is a technology used to accurately locate full bore blockages such as hydrates, wax, sand and asphaltene plugs along with other obstructions such as closed valves and stuck pigs in liquid filled systems.
Features & Benefits
Find-Block®s small size and non-intrusive approach allows operators to accurately confirm the location of blockages quickly, and develop the best remediation strategy.
FAQ
What mediums can Find-Block® be used in?
Find-Block® can locate blockages in all forms of fluid filled lines ranging from oil, water, chemicals etc….
Does the line have to be depressurised?
No, Find-Block® actually requires pressure to be within the line, generally at a minimum of 500psi / 35bar to achieve a stable result.
How many people are required to carry out a Find-Block® survey?
Find-Block® is operated with only one Field Engineer and as the equipment is hand carried, mobilisations can be arranged quickly to give accurate results in as little as 24 hours from first contact.
Can Find-Block® be used in hazardous areas?
Find-Block® can be used to accurately locate full bore blockages on lines ranging from as small as ⅜” and up to 24” diameters.
What size of pipelines can Find-Block® cover?
Yes, all Find-Block® units are suitable for use in Class I Division II) (Zone 2) hazardous areas.
