The Many Benefits of LED Lighting

LED lighting is fast becoming the popular choice within homes and commercial properties, taking over the traditional method of halogen bulbs. LED lights offer a number of advantages over halogen bulbs, including a longer lifespan, softer lighting and an increased efficiency.

LED strips are a popular choice within homes, and can often be found under kitchen cabinets to add gentle lighting as well as a modern touch. LED strips (or LED ribbon as they’re also known) are available in a vast range of colours, and many are able to be programmed to change colours through a remote.

LEDs are also much better for the environment, as around 95% of the energy within LEDs is converted into light, with only 5% wasted as heat. Less energy use in turn reduces the amount of greenhouse gas emissions into the environment.

Supermarkets are now opting for LED lighting, due to it being an incredibly efficient light source, as well as having less of an effect on the foods within the store. Traditional filament lighting gives off quite a bit of heat when on, which can spoil the foods on display within supermarkets.

However, it’s not just within homes and supermarkets that LED lighting is gaining popularity. Recently, scientists at the Heriot-Watt University in Scotland have utilised LED technology to be able to detect and diagnose cataracts within individuals.

The LED technology is able to measure cataracts at a molecular level, which then informs clinicians on whether patients require eye surgery. Clinicians are able to observe a fluorescence signal from proteins within the eye lens.

This is a huge advancement, as it means a diagnosis can be made before the often debilitating conditions appear. This allows for preventative measure to be taken early on, limiting the symptoms that those with early signs of cataracts would normally acquire over time.

Cataract treatments are often quite invasive, and so this new research is paving the way to a painless and efficient treatment of this eye disorder.

How Important is Geophysical Well Logging?

Geophysical or well logging as it's sometimes known is in fact of the most important processes in discovering oil, gas, ground water or minerals. So what is geophysical logging? It is the process of taking information from a sample of ground which is brought to the surface. Data can be taken either through a number of well logging methods including Resistivity, Density, Gamma or Sonic.

Why is this important?

You may need to take data from the ground for a number of reasons; depending on what it is you are looking to find.

Searching for oil or gas (hydrocarbon exploration) is no easy task as it is possible that there can be no visible surface indicators such as gas seeps or pockmarks. This industry will often use wireline logging to generate data from the rock properties. This is the process of dropping specialised logging equipment deep into the ground via wireline.

Water present beneath the ground's surface is known as groundwater. Unknowingly to some, it is cheaper and more convenient to use than other sources of water. With less exposure to pollution, it makes it one of the more favourable sources of usable water in the US. With this in mind, healthy and unpolluted groundwater that has been naturally filtered through the ground can be desirable.

Mineral exploration is also big business as commercially viable concentrations of minerals are a rare find. Professional mineral mining is highly organised and specialised field, and thus rely on a multitude of logging equipment to get highly reliable indicators of the ground.

Others might choose to hire out their equipment from logging specialists who are able to supply the latest equipment for the most accurate data. Some are extremely complicated to use, making it more and more suitable to hire complete logging services such as those offered by Robertson Geologging Ltd.

Getting to Grips with Velit

There’s quite a buzz in the geoscience world around Velit 1.9– a handy little plug-in which is rumoured to reach IHS Kingdom shortly, as well as already being an existing Module for Petrel based systems. We get to grips with this little module and we observe just how much of the buzz about this depth conversion software for the oil and gas industry is buzz, and how much of it is grounded, logical observations.

Initially, we had a slight misgiving about Velit. The heart of this module appears to be the creators – Equipoise Software which are linked to the respected and highly notable ERC Equipoise.

Essentially, it appears the close relationship between the two companies allows Equipoise Software to use ERCE’s data from 50 sites across the world and the experience of their partnerships with other companies in order to make good on Equipoise Software’s claim of Velit having a number of extensive libraries in order to assist with conversions.

The second claim Equipoise Software have about Velit is that it is more accurate than Petrel or IHS Kingdom. This originally struck us as quite a dubious claim; and  without investigation, we thought that this would likely be Velit’s undoing. We were wrong. Velit, objectively is much more accurate than most plugins and modules out there, and it’s mostly because of simplicity and the array of libraries offered. These libraries offer a series of solutions to a problem, and far more accurate results can be gleaned from getting in there and trying.

Velit 1.9 appears to focus on uncertainty involved with Depth Conversion, and as such 1.9 contains a large amount of enhancements we didn’t expect. Essentially, the best depth conversion techniques and uncertainty analysis can be ascertained in a much quicker fashion than even 1.7 – and as for speed, Velit is probably the quickest module out there right now.

Essentially, believe the hype. Velit is a rather impressive program, that deserves every one of it’s accolades.

Velit – Industry Standard Velocity Modelling

With an utterly extensive library of industry standard modelling methods, Velit for IHS Kingdom and Petrel is the definitive Velocity Modelling and Depth Conversion package for geoscientists and petrophysicists. Coming from London-based Equipoise Software, this handy tool can help reduce the margin of error in your team’s calculations with a very streamlined interface and usage of the Velit Wizard, as well as its truly extensive library.

With a catalogue of industry standard velocity modelling methods (for both well velocity calculation and seismic processing) you’ll have the confidence that only a precise picture of the geological surfaces you’re studying can give you.

Velit is very much about more precise calculations, but simplicity is built in.

Whether you’re using IHS Kingdom or Petrel, Velit improves the accuracy of your calculations extensively, and also enables you to use a very wide ranging number of features in order to truly work your data in a multitude of ways which is just simply not possible with other programs. As such, operational efficiency is far higher with Velit than without, and for that reason Velit is the top choice of many geoscience firms today.

Equipoise Software, the creators of this fantastic Depth Conversion and Velocity Modelling Package certainly understand that wide-ranging features as well as the interface certainly help with coming up with accurate models, and that the very best case technical velocity model can be produced with their program.

But how is Depth Conversion on Velit?  The answer is that the matter is simple, really.

Velit allows the user to try out a range of ideas to determine the very best velocity modelling situation for their study. Furthermore, it’s a quick little program – Velit appears to run rather quickly in order to allow the user to see exactly how different velocities and structural forms impact overall depth.
