Advanced Reservoir Characterization in a Multi-Stage Horizontal Well, using Chemical Tracer Technology

Posted by Callum Grieves

Jan 4, 2018 9:21:59 AM

Selection of the stimulation target in unconventional shale formations is an important factor that impacts well productivity. In thick unconventional formations, it is essential that operators quantify the production of each stage of hydraulic fracturing executed in the well, in order to establish the most productive rock. It is also important for operators to be certain that every section of the stimulated well is effectively contributing to overall well production and clean-out of all stages has been achieved. In addition, other development challenges include optimal spacing between perforation clusters, stages and wells, allowing operators to optimize drilling and completion costs and maximize enhanced ultimate recovery (EUR).

This Blog describes the application of chemical tracers in a multi-stage horizontal well to gain insight on stage productivity in order to plan an optimal field development strategy.

How to determine the best suited demulsifier for your application

Posted by Margaret Bletsch

Dec 20, 2017 3:15:04 PM

Scans aid plant personnel in determining which demulsifier is best suited for their application.

Tracerco’s scanning technology is an excellent means of measuring interface levels, whether between vapour and liquids, liquid and solids, or between two different types of liquids. Tru-Scan™ and PhaseFinder™ neutron scanning technologies can be used very effectively in trials of emulsion breaking chemicals to determine the best type and concentration to use in a particular vessel. This can lead to increased efficiency and significant cost savings as well as reduce the environmental impact of excess chemical use.

This blog will present two demulsifier trials that will show the difference in performance base on the presence or absence of an emulsion layer.

Tracing a path to better Oil & Gas Shale production

Tracerco, patented, pioneered and continues to enhance technology that enables the measurement of individual gas, oil, and water stage production along the length of a wellbore, without well intervention. This inexpensive technology provides confirmation that a wellbore is open to flow, identifies and quantifies stage flow contribution of each phase, and provides measurement of drainage area connectivity - simply by adding small amounts of unique chemical tracers to each stage’s stimulation fluid.

Unconventional Multi-Frac Wells – Reservoir Characterisation and Optimising Flowback Operations

Posted by Callum Grieves

Nov 6, 2017 1:50:31 PM

A customer wanted to test two different lithologies and compare the performance of both, in the gas window of the Neuquén Basin, in Argentina. For that reason, a slanted two-horizon target well was drilled, distributing 10 stages in the upper zone, and 10 stages in the lower zone. The intermediate zone, which was not considered a main target, received one stage.

21 unique organic gas and water tracers were added to each of the different stages of the well during stimulation. The injection was controlled and care was taken to tag all stages in the same way, ensuring that the tracers would penetrate deep into the fracture structure and make contact with formation hydrocarbons. Subsequent flowback and sample analysis for the presence of the injected tracers allowed relative gas and water flow from the different stages to be evaluated.

Diagnosing Problems in Liquid Liquid Extractors

Tru-Scan results assist with diagnosing problems even in a challenging process such as liquid-liquid extractors.OctoberBlogtowerweb1.jpg
One category of special applications is liquid-liquid extractors. Besides the fact that liquid-liquid extractors are not “typical” distillation or fractionation unit operations, what makes them a special application for Tru-Scans™? The source and detector system that is used in scanning measures density changes of the process materials inside the tower. With a typical fractionation tower there is a large density difference between the vapour and liquid phases. Thus there is a large density range between clear vapour and clear liquid to detect process or operating conditions existing in a typical fractionation tower – entrainment, foaming, flooding, internal damage, etc. But liquid-liquid extractors are liquid full, with no large vapour-liquid density difference. Meaningful scan results from a liquid-liquid tower rely on the density difference between the two liquid phases being significant enough to distinguish as some extraction processes involve two liquids that have comparable densities.
 
So what will a Tracerco Tru-Scan of a liquid-liquid extractor tower show?
Since we do not have the large vapour-liquid density difference to work with, the information learned from a scan of a liquid-liquid extractor is less extensive than for a “typical” fractionation tower but not any less important. As the following examples show, scans of liquid-liquid extractors can detect problems when the two liquid phases are not properly mixing, preventing the tower from doing its proper extraction operation.

How to fight fuel corruption with the implementation of a fuel marking program

Posted by Tracerco

Sep 26, 2017 1:10:26 PM


In many parts of the world, corruption is common and a part of everyday life. Apart from the corrosive effect this has on quality of service and availability of appropriate justice, this also has a negative effect on commerce. Reputable companies and people are unable to compete so the market is left to others who are willing to ignore the laws put in place to prevent corruption. Where this occurs, the economy suffers due to lack of investment which eventually contributes to poverty, pollution and poor health for the majority of the people who do not profit from corrupt activities. This is the type of environment where fuel fraud can flourish. In this latest blog, Tracerco will discuss how the implementation of a fuel marking program can help in the fight against fuel corruption.

Detect leaks in feed/effluent exchangers to the parts-per-billion range with chemical tracers.

On a regular basis customers see evidence suggesting the presence of a leak; such as a drop in process efficiency or the presence of a contaminant in product. This raises the question of where in the plant the leak is occurring or is the off-spec material do to some other problem.

In this latest blog, Tracerco, part of Johnson Matthey Plc, discusses how chemical tracers allowed the customer to replace a leaking exchanger bundle and restart the unit with minimal downtime.

Measuring Oil and Water Inflow in a Multi-Well Subsea Field Development Using Smart Tracer Wireless Technology

Posted by Callum Grieves

Jul 25, 2017 12:30:39 PM

In any deep water field development it is important to monitor oil and water production from all wells in order to manage fluid movement and maximize hydrocarbon output. The use of Smart Tracers integrated into a lower completion, alongside the use of waterflood tracers, provides a number of advantages over traditional oil and gas inflow measurement technologies, at a fraction of the cost.
