Rocsole Deposition Watch
You know it is there. But how much is there? How it is affecting other measurements? What is it's growth trend?
Rocsole’s Deposition Watch delivers the ultimate in deposition inspection accuracy for Oil & Gas and other industrial pipelines, enabling you to:
How Our Deposition Watch Works
Harnessing the power of tomographic technology, our Deposition Watch actually sees deposition inside a pipeline, monitoring the deposition inside process pipes in real time – without using a radioactive source. Using a sensor that is simple to install and that requires minimal maintenance, our system accurately measures many types of buildup including paraffin wax, hard scales, hydrates and more.
Once installed in-line, the sensor images deposition growth inside the pipeline in real-time and provides the deposition trend which is monitored to make informed decisions based on chemical type efficiency and dosage.
This video shows the cross-sectional and 3D imaging of calcium carbonate scaling formed on the wall of a pipe sensor installed into a pipeline with water-air flow. Our system is uniquely able to measure the deposition – even with the presence of multiphase flow with Rocsole's See Beyond -compliant technology.
Extend Cleaning Cycle and Reduce Production Loss
Rocsole's Deposition Watch application is used to measure the trend of a deposition in a pipeline. This trend is valuable and important information for operators: Based on the trend, the operator can either adjust process parameters (e.g. water quality, temperature...) or anti-scaling chemical feed in order to minimize the deposition growth and it's speed. This extends the required cleaning cycle of the pipeline causing reduction in number of routine cleaning, keeping the pipelines in effective production use, hence reducing deferred production and creating significant savings.
Annual Savings Potential
Annual savings from recovered production loss can be significant. Here is an example gathered from average oilfield collection stations. The table is based on oil price of USD 50 $/barrel. Additionally, reduced cleaning cycles create additional 20-30% – generally several million US dollars – in savings.

|200||USD 73,000 $||USD 365,000 $||USD 547,500 $|
|300||USD 109,500 $||USD 547,500 $||USD 821,250 $|

Measure Conductivity and Permittivity in Build-up Conditions
Measurement of background conductivity/permittivity might be a challenging task in build-up conditions. Conductivity is a base measurement in process industry and usually defines the quality of the product or salinity/mineral levels in incoming water. Permittivity is used, for example, to detect the water amount in oil. By applying Rocsole's See Beyond -technology, these measurements can be performed accurately through buildup layer. The principle is simple; Rocsole's device defines a tomographic image of the target, which can be interpreted into permittivity/conductivity values in the flowing medium.
Measure Mass Flow Build-up Conditions
Measurement of a mass flow in build-up conditions is a challenging task. Deposition on the pipe wall will affect the readings of mass flow measurement devices. Typically this is compensated by adding a calibration factor to the mass flow meter, which is only an estimate of the deposition speed. By using Rocsole's technology this problem will be overcome by adding a speed measurement with Rocsole's Deposition Watch. With Deposition Watch, mass flow meter is not needed. Speed measurement is giving the speed of the flow and Deposition Watch is giving the open area for the flow. Then the total mass flow is known.
