Deepwater Exploration Geophysics Challenges

May 17, 2013
Thumbnail image for Deepwater Exploration Geophysics Challenges

Frontier deepwater exploration in the Gulf of Mexico is becoming more difficult as we enter deeper water, much deeper reservoirs and potential under salt. As a result, we are faced with prospects that are supported by little to no amplitude, tiny seismic bandwidth as well as flat amplitude variation with offset (AVO) that sit in [...]

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 [...]

While on vacation in the Virgin Islands, our little group took the opportunity to spend a day on Anegada. This little isle is a part of the UK, the northeasternmost of all of the Virgin Islands and “unique in that it is composed exclusively of carbonate rock … and that its relief is only 25 [...]

Places I’ve been in the last two weeks, that is. D and I were on the US and British Virgin Islands for 8 days. I highly recommend the island of St. John, with day trips to the other islands including Jost van Dyke, Anegada and Tortola, over St. Thomas. Vacation is supposed to look like [...]

Russia! Bolide strike! Meteor impact! What does this all mean and why does the media keep using these terms interchangeably? Here: How to tell the difference between a meteor, meteorite, asteroid and comet. A bolide is a projectile fireball associated with meteor activity. Daring Bolide is the name of my Cretaceous-Tertiary Extinction tribute blog (apologies [...]

It’s February 2013, which means it’s my turn to host the Accretionary Wedge! The Accretionary Wedge is a geology blog carnival that was started in August 2007. Editions will be monthly (roughly) and hosted on a different geoscience blog each time. The accident-prone person that I am, I chose the topic of Geo Injuries. Look [...]

“Measure the strike and dip on this baby!” Rocks and Mardi Gras is something I’ve often considered renaming the blog. That or Rocks On The Rocks. You know, so I can make dumb Carnival time jokes like the one above. Tweet

Find Wet Stuff in Harder, Not-Wet Stuff

January 17, 2013

Remember when xkcd described how a rocket works using only the 1000 most commonly used words in the English language? “Saturn V Rocket” isn’t in the list, so it was reduced to “Up-Goer Five.” Now Theo Sanderson has created an Up-Goer Five text “editor” into which you can type anything you want and it warns [...]
