DSP-06 Particle Monitor

Sand production in oil and gas wells is a serious issue facing oil and gas producers. The challenge is not merely to avoid sand production, but also to increase commercial well productivity, as even small quantities of particles in the well flow can cause significant damage. As an operator you are interested in maximum production and profit from your wells, no matter what technology you use. Operators all over the world have made ClampOn their preferred supplier of sand monitoring systems, due to the patented technology that turns their wells into profit generators.

– ClampOn sensors with their high performance filter are unbeatable. The ClampOn SandQ with improved filtration of acoustic noise offers unparalleled performance, particularly when monitoring sand in challenging high-pressure, high-temperature (HPHT) conditions. »

 

The ClampOn DSP model incorporates a new filtering technique that makes the particle monitor an extremely useful tool for analyzing the true nature of sand production, helping to control it and finally, increasing the profit from the well! This filtering technique is the result of integrating our experience of thousands of wells, analyzing data and using the results to enhance the technology used in our DSP model.

The enormous capacity of the DSP sensor (the only one on the market) makes it possible to scan through a frequency range of 1 MHz 128 times per second. This illustrates the capacity of our technology and of the filtering technique that is at the heart of acquiring and processing sand data.

The following figures show a sensor installed close to a choke valve on a gas well operating at high pressure and high velocity. The figures illustrate what the signal looked like when using a traditional/alternative system compared to using the new DSP filtering technology. The new filter (ref. Figure 2) was able in this case to reduce unwanted noise by a factor of 500 compared to alternative solutions.

Digital signal processing – the way ahead
The DSP features complete digitalisation, eliminating analogue filters, circuits and amplifiers. The technology incorporates a powerful DSP unit with a large amount of flash RAM, running-feature packed modular software. The sensor operates simultaneously in several ultrasonic frequency ranges, allowing a whole series of new signal processing features to be implemented, including the latest filtering technique. Different types of chokes or flow conditions that generate sound unrelated to sand noise are analyzed and reduced dramatically via the advanced processing and filtering technique in the DSP model. It also improves accuracy and repeatability, important factors in quantifying sand production and a crucial tool in your daily sand management operation.

No other technology comes close to what the ClampOn 2006 model offers customers who need to generate profitable and sand-free production!
