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 [...]

I Made A Pretty Robust Well-To-Seismic Tie

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 [...]

Science Online: Information Sharing First; The Medium Is Not The Message

February 26, 2013

Recently, several geobloggers brought up an excellent point on science communication: Now that it has been established that researchers need to do more outreach to share their work, HOW? The barriers are plenty – sharing on the internet takes energy, time, some understanding of the different online outlets, putting words together in an explanatory and [...]

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 [...]

On Statistics, Risk vs. Uncertainty and Science Methods

January 11, 2013

Mean vs. Median: A runner friend posted this last night in that social media space which must not be named: “Just read that Americans average 4000 calories per day. Mind boggled. Also really want to know the standard deviation.” The immediate responses were mostly on the order of OMG THE JUNK-FOOD-SWALLOWING AMERICAN FATTIES. So, I [...]

Mass wasting is more like it. NOLADishu points me to a presentation given by Shell’s Donal Rajasingam at this year’s Tulane Engineering Fair. Within a pretty good collection of statistics on increasing energy demands and aging infrastructure, the above set of graphs on energy talent supply stands out. We don’t have enough people now, so [...]

Oil and gas production comes from oil and gas exploration. By the time a drop of oil is produced, decades will have gone into discovering, delineating and developing a subsurface reservoir. Exploration and field development require a long-term analysis of seismic images, rock and fluid properties from well logs, core data and any other remote [...]
