I Made A Pretty Robust Well-To-Seismic Tie

I Made A Pretty Robust Well-To-Seismic Tie post image

One of the tools in the geophysical workflow is the well-to-seismic tie. This is a calibration step involving the generation of a “synthetic seismic” from well data and comparing it to actual seismic data collected over the area. It ensures robustness or goodness of fit, i.e. that interfaces and intervals interpreted on the seismic data set match those same markers and units in the well penetration with a high level of accuracy. Think about it this way: If your seismic data doesn’t match what you see in the earth, what’s the point of working with it to draw conclusions about top, base, thickness and extent of the oil/gas reservoir?

So, I made a well-to-seismic tie. A Seismic Tie. Get it, get it? The reservoir section towards the base of the tie is based on Figure 11 from Roy White’s and Rob Simm’s seminal 2003 paper Good practice in well ties.

It took one black tie, one silver Sharpie, three different gauges of gold Sharpies and markers, and five hours of freehand drawing (including one hour spent pondering some geophysical concepts that came up as I drew the seismic traces surrounding the synthetic).

Everyone I’ve shown the tie to so far thinks I should get a booth at the SEG conference and make these to order. How about Geophysical Sartorialist as a title on my new business cards?

    Maitri, this is absolutely gorgeous as a designer tie all on its own. The delicious sartorial pun and geophysical data origin of the design sends it into orbit. All told, it’s the best tie I’ve ever seen! I wouldn’t consider making them to order, unless you could charge about twelve hundred dollars. Auction it for a good cause, if you like, but you look so cute in it you ought to just keep it and wear it to the dang convention yourself.

    Second Anita. I love puns, but I don’t tend to notice clothing. It wasn’t until I got to the third paragraph that I realized the title *was* a pun, scrolled back up to the photo, and had one of those “D’oh!” moments. Fantastically crafted- both the tie and the post. Thanks for the grin!

    Super! I expect D will appropriate it,

    Love it! And I really like Anita’s auction idea :)
