 Natural gas, along with solar and wind power, are the cleanest energy sources used today. Natural gas comes from about half a million wildpads in the United States and in total it contributes to about 35% of the electricity that we consume in the country. One of the problems with natural gas is that in its extraction and its production, you can't have leaks of methane. And there's a challenge to both workers, the environment, and also as a cost to the producers. So monitoring methane leaks becomes very important and actually imperative to the operation of wildpads. IBM is developing a scalable solution that could be applied on a global scale using cost-effective sensors that can be easily installed on any wildpad without change in the existing infrastructure. We're utilizing IBM's expertise for the past 15 years in developing nanophotonics technologies and putting them into optical sensors and in this case to detect methane. What we have is the world's smallest spectrometer that is essentially a sensor on a chip. Welcome. We're here at Southwestern Energy's Fayetteville Shell. Having industry partners is really critical to the development of the final solution and in this case we're partnering with Southwestern Energy and with that allows us to do is having the opportunity to deploy our current versions of the technology out in the field and understand from field experimentation the kinds of improvements that we need to make. In the Fayetteville Shell we have approximately 5,300 wells. We have just over 2,000 wildpads. Right now the technology that we utilize to find leaks is twofold. They do what we call an AVO survey, an audible visual olifactory survey, eyes, ears, and nose to observe for leaks. They come out at least every seven days. The other tool that we have though is to use the optical gas imaging cameras to do leak surveys which allow us to see leaks that you may not see with your eyes, smell with your nose, or hear with your ears. When you're surveying, you know, 5,000 plus wells it takes the better part of the year to be able to do the survey. The benefit of the technology that IBM is developing is we would have a sensor that we could locate on a well pad continuously that is measuring for leaks 24 hours a day, seven days a week. We are trying to achieve a balance between the environmental, social, and economic impacts of our production activities.
