Even though this is not within the usual scope of the blog, I hope that few will fail to see the beauty of these pictures of one of the earth’s more spectacular processes. I stumbled on the website, Extreme Instability, a couple of years ago, and thought that some of you might enjoy it, as well. If you also have an interest in tornadoes, or just nature photos in general, please check out his website.
If there ever was anyone who should be an earth scientist, it’s Mike Hollingshead. Here’s a guy who loves taking pictures of nature, and chasing storms. After dropping out of college a few times, and kicking around several uninspiring jobs, he just decided that he was going to make a living doing what he loved. And, here are some of the results…..

I was just notified that the instructions in the info page of the Culture Symbol Spreadsheet (posted on 02/08/08) were in error.
I had copied-and-pasted the intial text, for the info page, from another spreadsheet, and thought that I had made the appropriate changes. However, I may have uploaded the wrong version when I finished.
Sorry for any confusion, previously. I have corrected the version in the original posting, but here is the corrected Culture Symbol Spreadsheet, along with the ascii file that goes with it.

Imagine a wall of water, with a flow rate of over one million cubic meters (35.31 million cubic feet) per second, rushing towards you—an amount that is 100 times the average flow rate of the Mississippi River today!
If you were crossing the broad chalk ridge (indicated by the thin, red line in the gray-shaded image below) that connected Britain with mainland Europe sometime between 200,000 and 450,000 years ago, you could have witnessed this ridge-busting torrent that ultimately separated the two countries.

I’m sure by now, most of our blog visitors have heard about external hard drives. However, if you aren’t familiar with them, they simply allow you to add a hard drive to a computer by attaching it externally (via a plugin socket), instead of having to take the computer apart, and installing the drive internally.
This technology, which is commonly used for storing data, or backup files, has essentially replaced most tape drives. It has been around for quite a while, so I would also guess that many have even purchased “ready-built” enclosures, or like me, built their own.

Here’s the latest in the series of T/X Resources spreadsheets designed to help when you need to create symbols to import as an SMT culture layer.
In the image below, a variety of symbols have been created to highlight certain wellbore attributes. For example, they could represent producing formations, hydrocarbon shows, well log types, or test results. You can also vary the symbol sizes, and colors, to represent a ranking order, such as production volumes, etc. It doesn’t really matter what you want to show on your map—this is an easy way to do it.

How cool is this? I just found a new online spreadsheet application that allows you to share, collaborate, and publish spreadsheets that actually work when they are posted on a website, or blog. EditGrid received a very good rating from PC Magazine. The concept is somewhat similar to what is already being done with the online spreadsheet applications of Google Docs, and Zoho. However, the company focuses all of its efforts on the spreadsheet application solely, and apparently does a much better job at it, than either of its competitors.

This posting is an update of the ”Active Domestic Drilling Rigs and Seismic Crew Count” statistics which I created, and originally posted on the HGS GeoJob Bank ”GeoJob & Energy Statistics” page. However, the HGS page has not been updated since I “retired” as Chair of the Personnel Placement Committee, so I have decided that I would continue updating, and posting the graph here.

For those of you that haven’t had a chance to try out the Coblending feature in version 8.2 of SMT’s VuPak module yet, I would suggest that you give it a look. If you’ve never used anything like it before, be aware that it could max out your wowie-meter! Excuse the enthusiasm, but I like cool (and useful) technology.
(Back in the real world now) What is Coblending? It is just as its name implies—it is the ability to blend two different volumes of seismic data together, and display them both at the same time. Besides being very cool, it could also really be helpful with seismic interpretations—especially in complexly faulted areas.

For anyone who experienced the fluctuations in the oil business during the last 30 years or so, the descriptive “roller coaster ride” in the title only partly explains our adventures.
At the time of the hiring peak of the oil industry—December 1981—there were nearly 1.18 million people employed in the mining industry (a Bureau of Labor Statistics category which includes the oil industry), as seen on the blue employee graph in the image below (generated with Golden Software’s Grapher program).
Oil prices had just peaked at $34.59 per barrel (average monthly price) nine months earlier, but it was still selling at nearly $31 per barrel that December. During the same time period however, March to December 1981, industry unemployment had crept up to 7.5 percent, from just 4.4 percent (black graph in the image below)—an increasing trend that went unappreciated by most of us at the time.

I got the idea for today’s posting from a client’s search for a critical well log—he’s been searching for it for a while now, but hadn’t been able to find it, so far. So, I suggested a few more companies to search, and hence this posting. Since logs are so important for what we do as geoscientists, I thought that the list of sources (in no particular order) that I sent to him, might be helpful to others, as well.

Anyone who has visited the Houston Geological Society’s (HGS) GeoJob Bank, or more specifically the GeoJob & Energy Statistics page, is bound to recognize this graph. During my nearly six-year tenure (2000-2005) as Chair of the Personnel Placement Committee, I created and updated the industry-related graphs on the Statistics page (amoung my many other duties). However, since I “retired” from the Committee in late 2005, the graphs haven’t been updated, so I thought that this would be a good venue to revive some of the graphs, and keep them current with updated information.
This first graph, in a series to come, is the oil and natural gas price curves for 35-years—from January 1973, through the last available data in December 2007. It was created from downloadable data from the U.S. Department of Energy’s (DOE) Energy Information Agency, and the Federal Reserve Bank of St. Louis, saved to a spreadsheet, and then graphed with Golden Software’s Grapher program.

If you’re like me you probably spend long hours at the computer. Because of this, it’s easy to develop Repetative Stress Injuries (RSI) if you’ve improperly positioned yourself, your computer equipment, or your office furniture.
I just ran across a few websites that may be helpful and informative as to the proper, ergonomic placement of these items.
The U.S. Governments Occupational Safety & Health Administration (OSHA) website provides a lot of useful information concerning Computer Workstations, and provides a Workstation Checklist, and Workstation Purchasing Checklist, Good Working Positions, and Selecting Workstation Components .
Even with the correct design and placement of the workstation, RSI can become a problem unless the risk factors are reduced by Work Process and Recognition, and the Workstation Environment.

The following is an example of an easy method to import culture lines into an SMT project, using a spreadsheet formatted as an SMT culture line file. Note that this is also applicable for importing polygons.
Suppose you have an SMT project that includes both 2D and 3D seismic data, but you only want to show the 2D line location overlays without the 3D line overlays, to reduce map clutter. Normally, SMT’s 2d/3dPak module only has the option to have all seismic line locations turned on, or to have them all turned off.
In the examples below, the first image, annotated “WITH ALL SURVEY LINES” is how a map would look with the Display Survey Line Option selected (Surveys>Survey Annotation> Line Options>Display Survey Lines). Often, this creates a lot of map clutter (in my opinion), especially if you have many 2D lines, or they are concentrated in one area. This map clutter can distract from the structure map, or other focus of the display.

Do you have a new 3D seismic volume that you need to review quickly? Maybe you just need to scan it to get a feel for the structural trends, or for quickly finding new prospects to concentrate on.
Whatever the case, SMT’s VuPak Chair Cut Animation, a common method of seismic visualization, is a good approach to use for the evaluation. It allows for the simultaneous viewing of three different planes of seismic data, as seen in the image below—Inlines (vertical data surface facing forward), Crosslines (vertical data surface facing towards the left) and Time Slices (horizontal data surface, facing upwards).
The data set being displayed below is a Coherency volume, which is an excellent seismic attribute for highlighting subtle structural and stratigraphic changes in the data. In this case, we’re looking for the major fault trends. Seconds after opening the volume for viewing, we find that there are two significant faults surfaces (the dark purple, linear features being highlighted by the red arrows), which can be seen traversing through various faces of the cube of seismic data volume.

Being in business for myself, I have to wear several “hats” during the day. Not only am I a Geophysicist, but also must be adept at geology, marketing/sales, finance, etc. (and now running a blog). Whew, sometimes there doesn’t seem to be enough time in the day!
Another one of my duties, which often seems to take a lot of my time, is being the unofficial, computer support person for several computers: three of my own, one in a currently active client’s office, and three for my family—all with Windows XP (I’ve had no desire to jump to Windows Vista yet, with all of its reported problems, and slowness). It seems that I’m continually fixing something that is broken, corrupted, won’t work, etc., or continually searching for upgrades/fixes, and boy do I get frustrated with the seemingly never-ending problems.
As a result, I have recently started to investigate the possibility of using Linux as an OS (operating system). Let me state here, that I’m not an expert yet, by any means—I’m still way down on the learning curve. There’s still a lot to learn, but I thought that I would share some of what I have found out so far. Here’s a recent Linux user survey that I found, about some of the leading Linux distributions (distro’s in geek speak).
