All I Really Want to Do: My Time at OTC

Every year around the same time something magical happens in Houston.  It’s a time to come together and celebrate what we’ve been able to accomplish in a year and what we have planned for next year.  It is also a time to hawk your company’s wares, to wine and dine potential customers, and to show how your company out shines all the others.  What is this event? Is it Christmas, Valentines’ Day, or Guy Fawkes Day? Nope, it’s the Offshore Technology Conference (OTC).

The OTC (not to be confused with the OC) is one of the 200 largest trade shows in the nation.  This year it was held from May 1 through May 5. It consists mainly of companies that make things or provide services for the offshore oil and gas industry.  It brings an extra 50,000 plus people to Houston each year (people living out toward Reliant Stadium do not look forward to this). This includes everything from oil rigs, engines, life boats, shoes, and rooms (yes you can take a look at perform room).  When most people think of the offshore oil and gas industry they just think about the rigs, they don’t think about all the different services and products that are going on behind the scenes.  For example: shoes.  People working rigs in the Gulf need shoes.  Should they just bring there own?  Should the company they work for provide them with shoes that are kept to a certain design and safety standard?  And where will the people on the rig live?  What type of recreation should they have on the rig? How will the rig data be stored or transferred?  How tough do monitors have to be?  Should they be touch sensitive? As you can see, there are a lot of products and services most people never think about (I even got to see some solar powered warning lights).  

Each booth tries to out do the others.  There are models of ships and rigs, cheerleaders, 3D  TVs, large konect like toy rollercoaster. “There was much of the beautiful, much of the wanton, much of the bizarre, something of the terrible” (Poe’s Masquerade of Red Death).  Although my favorite part each year is the swag.  Swag stands for the stuff we all get.  The highlight of any conference is the random stuff you walk away with.  And since each different company is trying to tempt you away from all the others, it can be an ADDOS’s person dream (Attention Deficit Dis… Oh shiny).  Some of the highlights I’ve had throughout the years include a ball made of interlocking pieces that fold out and flip sides when tossed in the air, a list of all U.S. navy vessels, a combo flashlight, tape measure, screwdriver, and leveler, and, this year, two pieces of curved paper that create an optical illusion.  Most of the swag I collect will eventually be given away to friends, family, and passerby’s. 

There is more to OTC then just cool cutting edge technology and free stuff.  If you’re a veteran you have figured out a way to live off the land.  Most booths will have a bowl of candy to hand out to people.  Others have water and other libations.  In the morning some have pastries (one booth this year had freshly baked cookies).  Around lunch time, the larger and fancier booths put out lunches.  You could grab a ham and cheese sandwich or try to hunt down the stir-fry.  You could go an entire week without buying food.

Now there are a few people (50,000) who do go there for other reasons.  Each day there is a bewildering array of classes and papers on talks about all the latest and greatest in technology, procedure, science, and law.  Attendees go to learn.  I picked up several interesting periodicals talking about the new large fields off the coast of Israel and Brazil and all the challenges of bringing them online. 

There is also a teacher and student workshop.  The workshops are put on by the wonderful people at the National Energy Education Development Project (if you’ve been keeping up with the blog, they will sound familiar). 

All in all, the OTC is an experience right up there with Disneyworld and the AAM annual meeting.  For people in the industry it is a must.  And for those not in the industry it is a chance, like Jane Goodall in Africa, to observe a unique industry in its natural habitat.

Deepwater

On April 20, 2010 the Deepwater Horizon oil rig exploded in the Gulf of Mexico. Eleven people were lost and over 5,000 barrels of oil a day have been pumped into the gulf. It is a tragedy and one of the worst environmental disasters of all time.

This blog will help to explain why there is oil offshore, what an offshore oil rig is, what cementing and containment domes are and how we can help.

Crude oil is made form the desiccated remains of microscopic organisms that plied the water ways millions of years ago. They died (the very theme of nature), fell to the bottom of the ocean and were covered by layers of rock, sand and other debris. Through compression and temperature they were converted into hydrocarbons (crude oil and natural gas). Thanks to plate tectonics, many of these hydrocarbon reservoirs have ended up on land, but there are also many that are still under the ocean floor.

The Mineral Management Service has estimated that there are 17.8 billion barrels of oil off the cost of America (for comparison the Ghawar field is Saudi Arabia has 60 billion barrels). So why do we drill for oil offshore?  Here are a few numbers that will help explain.  America uses 21 million barrels of crude oil each day (most have been refined into gasoline), but we only produce 9 million barrels a day.

The two countries that we import most of our oil from, Canada and Mexico, also have large offshore oil projects. Canada produces around 368 thousand barrels a day and Mexico produces 2.2 million barrels form their offshore wells. Other counties such as Saudi Arabia, Iran and Russia also have offshore production.

So what are offshore platforms? An offshore oil rig is like an extreme onshore rig. Not only does the rig have to drill thousands of feet through the earth, there is also have hundreds of feet of water on top of the drilling site. The rigs must also survive whatever the sea can toss at them, whether it be waves, hurricanes or tsunamis. There are many different types of offshore oil rigs. Deepwater Horizon was a semi-submersible rig, meaning that there were large tanks that would fill with water to submerse some of the oil rig, so that it would not move off the site it was drilling at. It can be put in water depth from 200 to 10,000 feet. A fixed platform is fixed in place by cement or steel legs and can go up to 1700 ft. A jacked up platform can use their legs to jack the platform up till it is above the water level, and then jack back down to move to a new location. They usually operate in up to 400 ft of water. A drillship is not a platform at all but a ship that can be used to drill wells. Its uses a series of thrusters to maintain position and it can operate in up to 13,000 feet of water.

So which one is the best one? Because all the different offshore options can operate in varying depths and environments, it really is dependent on the location.

Cementing has come up a lot in the news recently. Most people may not know what that means. After a well is drilled and the casing is laid in, a special mixture of cement can be poured down to help support the well. It can help to keep the pressure constant, to reinforce the well walls or to plug up a well that is no longer producing. The cement used for the wells very from well to well. The mixture is based on the rock in the well and other variables such as the pressure at different depths.

If the pressure becomes too much an uncontrolled release can occur called a blowout. It can be oil, natural gas, water or a combination of two or three of those. One the most iconic examples of a blowout is Spindletop. No one wants a blow out. Not only does can it cause environmental damage but it can threaten the very lives of the people who work on rigs. To stop this there are automated measures and human control methods. For example, an operator could notice a change in pressure in the drilling mud. He would then try to relieve the pressure in a controlled method. If all else fails a blow out preventer can be used. A blow out preventer is a device that physically plugs the well so nothing can escape.

So if a blowout happens, then what? What happens when an offshore oil rig can’t stop producing such as Piper Alpha or Deepwater Horizon? Remote operated vehicles (ROVs) can be sent down to assess the situation and try to stanch the flow. A remotely operated vehicle is just that, a vehicle that is operated remotely by a person. If the ROVs can not stop the well a containment dome can be lowered down to cover the leak. A containment dome works by covering the area and then channeling the pressure off, and in this case to collect the crude oil. The first containment dome lowered down on the Deepwater Horizon was unsuccessful due to a build up of methane hydrates (or fire ice) on the dome. There are plans to drop a smaller dome, which would be easier to heat up if methane hydrates forms.

There are also efforts to contain and remove the oil that has come up. One of the choices is to burn off the crude oil. This can only be done under certain conditions, such as low winds, calm seas, and can not work on every spill. Another way is to put a boom around the spill to contain it and reclaim it. If the oil is on the surface, a skimmer can be used to gather and separate the oil. Chemicals can be sprayed on the oil spill to make the oil disperse or to clump together. Two types of dispersants have been spread on the Deepwater Horizon spill to help disperse it.

Another way to try and stop the oil that is coming out of the well is to drill a relief well. This would take the pressure off the well hole (it is like opening another hole in a shaken coke bottle to take the pressure off the main hole).

So what can we do? The national wildlife federation has created a page to help with that. Check with your barber or hair stylist to see if you can donate hair to make a boom. The best thing you can do is become energy aware. To understand where we get our energy from and how much of it you use. That is the first step to true energy independence.
