Depth Conversion Techniques

Depth Conversion in particularly complex land areas can be difficult to determine whether it is reliable or not. The limited amount of seismic data, and the quality of it can mean it lacks accuracy and precision. However, despite recent breakthroughs in the technology of seismic imaging, precise depths aren’t always achievable with depth-imaging techniques.

Depth Conversion, therefore, comes top over alternative techniques to determine depth.

What is Depth Conversion

Depth Conversion is the measure between time, depth and rock velocity to determine how deep a reservoir is and how easy it is to excavate. This method is used when needing to drill far down into the earth’s surface, typically used in the oil and gas industry.

How Depth is Measured

The depth of the Earth’s surface is measured through soundwaves and the time it takes to get from one end to the other, and back again. The source of the soundwave is placed at one end, with a grid of receivers along the Earth’s surface at precise intervals so each part of the Earth’s surface can have its depth determined by using the time it takes to get from one point to another.

Measuring soundwaves alone isn’t enough to know exactly what the Earth’s surface is made from. Due to the varying nature of different rock types, these can distort readings of depth and shape due to their velocity. Rock velocity is as important, or even more so, as depth conversion it. Rock velocity tells us how hard or soft a rock is, which will help us in knowing how easy or hard it will be to drill down into the Earth’s surface. Rock velocity can be determined by using a geological hammer to see how fast rocks travel. Slow rocks “thud” or “squelch” whereas fast rocks “ding”.

From this information, many geoscientists and oil and gas industry experts use specialist depth conversion and seismic inversion software to start modelling data they have received to produce quick and effective results. This software can make even the most complicated data easy to read and into real and working models without over complication. With regular updates, depth conversion has never been so easy and with accurate results too!
