Because it works with flammable and even explosive materials, the oil and gas industry necessarily makes high demands of its fire protections systems. Many traditional solutions are, however, no longer acceptable because of concerns related to global climate change-a top of mind issue for the oil and gas industry. Joe Ziemba of 3M Company looks at a new alternative that offers many benefits.

To provide fire protection in the offices, equipment rooms and other confined spaces that form part of onshore and offshore oil and gas installations, halon-based extinguishing systems have, in the past, been a popular choice. As an extinguishing agent, halon is efficient, clean, relatively low in toxicity and, in its heyday at least, it was inexpensive.

It does, however, have two crucial shortcomings – as a brominated fluorocarbon it does significant damage to the Earth’s ozone layer. In addition, halon is long lived in the atmosphere and has a high global warming potential. This led to the production of halon being phased out in the early 1990’s to comply with the Montreal Protocol, and most manufacturers ceased to make halon-based fire suppression systems around the same time. Clearly, an alternative was needed, and the most widely adopted class of compounds were hydrofluorocarbons (HFCs). These agents certainly have the required zero ozone depletion potential, but they fall short in another area – their global warming potentials are substantial.

Dade City, FL—August is National Eye Exam month, the perfect time to recommend that your patients schedule a comprehensive eye exam.

The Vision Council of America notes that 12.2 million Americans require some sort of vision correction but don't use any. Nearly 50% of parents with children under 12 have never taken their children to an eyecare professional.

Here are five reasons to share with your patients about why they should have an eye examination:

1. Save a headache. If you have been having unexplained, constant headaches, your solution could be visiting your optometrist. An eyecare professional can pinpoint the problem of your headaches.

2. Perform well in school. One out of every four children has vision problems. A common reason children fall behind in school is poor, undetected vision. Taking your children to the optometrist can detect an eyesight problem that can contribute to learning and reading difficulties.

3. Determine prescription. Your eyes change over time. An optometrist can determine if you need eyeglasses or contact lenses, or if you need a stronger prescription to reduce eyestrain and help you see better.

4. Detect eye conditions. An optometrist is able to spot the early onset signs of diabetes, high blood pressure, glaucoma, and high cholesterol just by conducting an eye exam.

5. Prevent conditions. Many serious eye diseases often have no symptoms. An optometrist will see the early signs of diseases, such as macular degeneration or cataracts. Early detection is important to prevent serious damage.

Shale has been the primary driver of US gas supply growth since 2007, and the Marcellus shale has been the largest single contributor to rising production.

Marcellus production topped 14.5 bcfd in March and is expected to account for nearly one fourth of all US gas output by 2015, according to a report by Morningstar Inc.

The Marcellus's eminent position stems, in part, from the ability of wells in the formation to come online at high initial production (IP) rates and to sustain those rates for longer than wells in other shale formations.

Morningstar found the median Marcellus shale well continues to flow at 100% of its initial production rate for its first 6 months.

"Once you drill a well, it keeps flowing at a high rate for an extended period. That is very distinct from pretty much any other shale play that we've seen so far in the US," Mark Hanson, Morningstar equity analyst and coauthor of the report, told UOGR. By comparison, Hanson said, a well in the Haynesville shale in Louisiana may see production decline 50% during its first 6 months online.

Morningstar analyzed state data showing the performance of nearly 4,500 wells in Pennsylvania and more than 1,000 wells in West Virginia dating back to 2009. Researchers looked at IP rates, decline rates, drilling and completion activity, and sweet spot migration, among other factors.

Researchers found production rates for wells across the Marcellus generally decline 65% over any given 3-year period. However, Hanson said, the formation is not homogenous and some counties see meaningful production declines from initial flow to the 6 month mark.

Conversely, in a handful of counties, production rates actually increase 10-30% during their first 6 months online. Morningstar pointed to examples of this in Greene, Susquehanna, and Wyoming counties, Pa.

"Such counterintuitive results (most shale gas wells experience steep declines over the first few months) help explain why Marcellus production has risen faster than analysts' forecasts," the report said. The median, 30-day IP rate of Marcellus shale wells was found to be 5 MMcfd in mid-2013, up from less than 3 MMcfd in late 2011, and it is not unusual for companies to bring wells online at much higher rates.

Southwestern Energy Corp. said in November that one of its Susquehanna County wells, the Seamen 2H, flowed at a peak, 24-hr initial production rate of 32.2 MMcfd. And Cabot Oil & Gas Corp. reported a 10-well pad it operates recently came online at a combined IP rate of 168 MMcfd, implying an average IP rate of 16.8 MMcfd/well.
