Depth Conversion is used when measuring how low you need to drill the be able to obtain something, this is commonly used when drilling for oil. Depth Conversion sounds difficult but when you have a basic understanding of what it is, it all begins to make sense. Depth conversion is determined by measuring the time in which it takes for sound to travel from a particular source, to reflectors, bounced back and picked up by the receivers. You may familiarise this with an echo that bounces off cave walls and eventually the sound reaches back to you.

So now, imagine telling an operator to dig a well of an unknown scale without knowing the structure of the rocks underneath. Not only can it be very impractical, but it can be dangerous and even impossible to carry out. Due to the variation in rock types and their velocity, potential reservoirs can vary dramatically depending on the depth size and shape of the rocks underground.

Depending on the different rock types will depend on what machinery to use. A porous rock will have a completely different structure to one that is less porous.

To test the soundwaves, huge trucks are brought to shake the earth, used on large scales, with microphones set up every 25meters which measure the soundwaves across the earth. Conversion from time to depth is imperative in every project and there are a lot of things that can go wrong along the way, leading to bad workflow, mistakes, money wasted and most importantly putting lives at risk.

It’s from this data that it is inputted into specialist software showing up spots that are less or more dense than others.

However, handy software, Velit, which can be used as a plugin for Petrel and IHS Kingdom, adds extra functionality, improved workflow, and allows you to get much more from your data with much more accurate results. Having a reduced margin of error is extremely beneficial in this line of work because it can literally be a case of life or death. As well as this software, to ensure your team knows how to get the most out of it and how to incorporate it in there work, many training courses are offered on not just Velit software but also their sister product InSeis which is used for Seismic Inversion.

So whether you wish to further your line of work with new software education or you know someone who is new to the industry. These training courses are highly beneficial, keeping content relevant, strong and up to date with new methods and improvements that will drive your career further.
