States already regulate hydraulic fracturing well, officials testify

States already regulate hydraulic fracturing aggressively and effectively, and a federal law would be redundant, two officials told a US House subcommittee on June 4.

"As the head regulator of oil and natural gas development in North Dakota and an office of the Interstate Oil and Gas Compact Commission, I can assure you that we have no higher priority than the protection of our states' water resources," said Lynn D. Helms, director of North Dakota's Department of Mineral Resources.

"Within our respective states, we are responsible for implementing the state regulations governing the exploration and development of oil and gas resources. First and foremost, we are resource protection professionals committed to stewardship of water resources in the exercise of our authority," said Scott Kell, president of the Ground Water Protection Council and deputy chief of the Minerals Resources Division in Ohio's Department of Natural Resources.

But a former director of New York City's Water and Sewer System told the House Natural Resources Committee's Energy and Minerals Resources Subcommittee that current state regulations are inadequate.

"All the improvements they've talked about are welcome. What we're dealing with is good housekeeping. All that has to happen is to have 2% of the wells that are planned go south and we'll have thousands of incidents," said Albert F. Appleton, who is now an infrastructure and environmental consultant.

'Take the initiative'

"The industry could help by developing biodegradable fracking fluids. I don't understand, for the life of me, why it hasn't taken the initiative," he added.

They testified, with Douglas Duncan, associate coordinator of the US Geological Survey's Energy Resources Program, and Mike John, eastern division vice president of corporate development and corporate resources at Chesapeake Energy Corp., at a hearing called by the subcommittee's chairman, Jim Costa (D-Calif.), to examine issues associated with shale gas production.

"Shale gas actually is not new. It's been developed for almost 50 years and could play a sizable part in the US energy portfolio. A single play, the Barnett shale, produces 6% of all gas consumed in the US today," he said in his opening statement.

"While this is a great opportunity for the country to have access to a significant reserve of clean burning fuel well into the future, for some unfamiliar with the oil and gas industry, it has raised concern over the potential impact to water quality and use from the practice of hydraulic fracturing," said Doug Lamborn (R-Colo.), the committee's ranking minority member.

"Hydraulic fracturing has been used by the oil and gas industry since the late 1940s," he continued. "More than 1 million frac jobs have been completed in the US since the technique was first developed. And there have been no demonstrated adverse impacts to drinking water wells from the fracking process or the fluids used in the process."

Another subcommittee member disagreed. "This is not an issue that's newly important. It's been around for a long time," said Maurice D. Hinchey (D-NY). Congress dealt with it when it passed the Safe Drinking Water Act in 1974, but a later group of federal lawmakers exempted oil and gas drilling under the 2005 Energy Policy Act, an action which needs to be reversed, he said.

Will reintroduce bill

Hinchey and Diana DeGette (D-Colo.) said following the hearing that they plan to reintroduce a bill next week that they initially offered in 2008 which would bring oil and gas drilling back under the SDWA. "This bill would make drillers subject to the same reporting requirements as any other industry under the SDWA. They would have to file reports about what chemicals are in the fracking fluid," she told reporters during an afternoon teleconference.

"We are being contacted by people from around the country who report bad experiences from drilling near their property. We're not trying to do anything revolutionary. We're trying to restore a safe, solid piece of legislation that was passed back in 1974," said Hinchey, who also participated.

But Kell said that reports of problems have been exaggerated. "In recent months, the states have become aware of press reports and websites alleging that six states have documented over 1,000 incidents of groundwater contamination from the practice of hydraulic fracturing. Such reports are not accurate," he said.

Officials from Ohio, Pennsylvania, Pennsylvania, New Mexico, Alabama, and Texas wrote letters to GWPC Executive Director Mike Paque disproving the reports, Kell continued. A sixth official, from Colorado, did not respond because he had not been on the job long enough, he added.

In his May 29 letter to Paque, Texas Railroad Commission Chairman Victor G. Carillo said that a majority of 354 active groundwater cases associated with the oil and gas which were reported in the state in 2007 involved "previous practices that are no longer allowed or result from activity now prohibited by our existing regulations. A few cases were due to blowouts that primarily occur during drilling activity. Not one of these cases was caused by hydraulic fracturing activity."

Safely used since '40s

Mike John of Chesapeake Energy acknowledged that hydraulic fracturing has become somewhat controversial, but added that it has been safely used since the 1940s. "It is very important to reiterate that these deep shale formations exist thousands of feet below the land surface and are separated from freshwater supplies by layers of steel casing, protected by concrete barriers as well as millions of tons of hard, dense solid rock geologic formations," he said in his written statement.

He also submitted a fact sheet which listed fracturing fluid additives, main compounds, and purposes, including hydrochloric or muriatic acid, borate salts (which maintain fluid viscosity as temperatures rise), petroleum distillate (to "slick" the water to minimize friction), and ethylene glycol (to prevent scale deposits in the pipe). "Additives used in hydraulic fracturing fluids include a number of compounds found in common consumer products," the fact sheet said.

But Appleton characterized fracturing fluid ingredients as "a witch's brew of toxic chemicals, nearly all of which are intrinsically hazardous to the environment." They are dangerous, he maintained, because they don't biodegrade: "Once in the environment, they stay there. Most of them bioaccumulate. The remainder volatize, removing them from water and land, but adding them to the atmosphere where they become contributors to global warming."

Hydraulic fracturing introduces these chemicals into the environment by leaving a significant portion of the fluid underground, where it is free to migrate into groundwater, he continued. More oversight is needed to assure that wells are properly drilled so their integrity is not breached, that the fracking fluids are properly handled and not spilled, and the liquids are properly disposed, he said in his written statement.

Appleton said that shale gas drilling is inappropriate in any area that is a major drinking water source, that zoning is essential particularly in rural areas to minimize impacts of incompatible land uses, and that a system of impact payments to local rural governments will be needed to deal with community infrastructure issues.

'Inaccurate information'

That drew a strong reaction from one subcommittee member. "Mr. Appleton essentially said the oil and gas industry is making so much money it can afford to be over-regulated," said Dan Boren (D-Okla.). "Well, natural gas producers in my district are stacking rigs and companies like Frac Tech are laying off employees. I'm proud that I'm supported by the oil and gas industry because it employs a lot of people in my state, and I'm tired of people trying to shut it down with inaccurate information."

Hinchey pressed Kell for information about oil and gas industry support of the GWPC. Kell said that the group gets its main support from government agencies including the US Department of Energy, the Environmental Protection Agency, and numerous industries besides oil and gas. "Our opinions are not for sale. Our emphasis is on protection of water resources," he declared.

Quite a few states already require disclosure of ingredients in hydraulic fracturing fluids, he added. "As a member of the GWPC and an Ohio official, I don't believe any federal regulation of hydraulic fracturing is necessary," he said.

When Cynthia M. Lummis (R-Wyo.) asked what impacts federal hydraulic fracturing regulations would have on state programs, Helms responded that Alabama spent two years rewriting its regulations in the 1990s after losing a lawsuit brought by an environmental organization. "We're also concerned that requiring additional regulations will divert states' resources from other higher priority programs," Kell said.

When she was asked about this during her teleconference, DeGette replied: "The reason we passed the [SDWA] to begin with is that we decided safe drinking water is a national priority. Also, water like any resources crosses state lines. I'm very proud of Colorado for passing new stringent regulations, but other states haven't followed it. Further, the SDWA is being administered by state agencies in 34 states already for other industries so this wouldn't be an additional burden."

Research and Markets: Chinese Hydraulic Components Markets

Research and Markets (http://www.researchandmarkets.com/research/e7bb4c/chinese_hydraulic) has announced the addition of Frost & Sullivan's new report "Chinese Hydraulic Components Markets" to their offering.

Construction Sector Does Some Heavy Lifting in the Chinese Hydraulic Components Market

The global economic downturn has had far-reaching effects across regions and markets but the Chinese hydraulic components market has managed to stay buoyant because of the demand from construction and industrial machinery sectors. The active real estate market and construction boom will help sustain this trend, especially with the 2010 World Exposition expected to stimulate greater construction activities. Moreover, relief work in the aftermath of natural disasters necessitate numerous excavators, loaders, bulldozers, cranes, and many other heavy construction machinery in which hydraulic components are key parts. Apart from construction, hydraulics components will find application in agricultural and farming machinery. Increased defense budgets due to the need for advancements in aircraft and fighter planes are also aiding the growth of the hydraulics component market. Additionally, the escalating investments in marine and processing industries bode well for market vendors.

The market will be gladdened by the increasing migration of manufacturing to China, since the relative low labor and material costs in the country are huge attractions for manufacturers. However, only the lower-end hydraulic components production is shifting to China, reducing the quantum of benefit. The country is a hot destination for manufacturers from other industries as well and they are not fighting shy of making heavy investments. "Due to the expanding hydraulic components market and the appreciation of Renminbi (RMB) to the U.S. dollar, many foreign investors will further increase their investment in China by setting up more sales offices and enhancing R&D budget," says the analyst of this research. "Foreign participants are expected to overwhelm the Chinese market and maintain their growth trend to increase the revenues and to raise the overall technology expertise of the Chinese hydraulic components manufacturers."

Manufacturers are hoping to pique end-user curiosity by launching many hydraulic-related projects. The flip side of building up such interest is that end users begin to have greater requirements, which tests medium- and small-sized manufacturers. Meanwhile, cost control is fast becoming a challenge due to the intensifying price wars between domestic and foreign manufacturers. "Nevertheless, with new materials and better hydraulic fluids being adopted in production, cost cutting and extended life cycle seem possible," notes the analyst. "Owing to the advanced technology, hydraulic components can better fit into the working environment and reduce the cost of installation and maintenance." The cylinder segment is the most affected by the improved technology and lower costs of domestic products. Greater demand for localization has had large companies expand their product range and indulge in mergers and acquisitions. They have also been establishing more direct trade offices in China to widen their coverage and offer better after-sales service.

This Frost & Sullivan research service titled Chinese Hydraulic Components Markets provides total market size, market and technology trend, and market segment revenue breakdown. In this research, Frost & Sullivan's expert analysts thoroughly examine the following markets: cylinders, valves, pumps, motors, and others.

Key Topics Covered:

-Chapter 2 Total Hydraulic Components Market: Impact of the Primary Challenges (China), 2007-2014

-Chapter 3 Total Hydraulic Cylinders Market: Market Drivers Ranked in Order of Impact (China), 2007-2014

-Chapter 4 Total Hydraulic Valves Market: Market Drivers Ranked in Order of Impact (China), 2007-2014

-Chapter 5 Total Hydraulic Pumps and Motors Market: Market Drivers Ranked in Order of Impact (China), 2007-2014

Parker to show hydraulic filtration solutions

Parker Hannifin, a provider of motion and control technologies, will show three hydraulic filtration products at Hannover Messe 2009 on 20-24 April.

According to the company, the products, which have been developed considering environmental matters, simplify the filtration process and integrate filtration solutions into hydraulic system assemblies.

At 414bar maximum working pressure and flow options up to 700 litres per minute, the World Pressure Filter (WPF) series incorporates eco-intelligent performance media that are intended to reduce disposal waste and cost by more than 50 per cent.

Parker Filtration offers hydraulic system designers the possibility to integrate various system functions into single components.

This can result in cost reductions for the application in manufacturing and end-user maintenance and can realise more compact solutions and lower environmental impact by reducing leak points, for example.

Integrating high-pressure filters such as the WPF with quality media and patented elements is intended to guarantee the quality of filter performance and to maximise system component protection.

The filtration media has been designed in a patent-protected element range, whose element design is claimed to reduce time to change and eliminate oil spillage during changeover as the element remains in the bowl when removed from the filter head.

The bowl of the WPF filter can be quickly removed as no tools are necessary and the integral element requires the minimum of space for removal, allowing the filter envelope to be kept to a minimum.

The WDPF high-pressure duplex filters include a solution to allow remote switching.

Instead of the manual operation of the main duplex valve and equalising line, Parker's hydraulic solenoid valve technology makes a safe and remote operation possible with the WDPF filter.

This process can be fully automated; when one filter element gets contaminated, the filter condition indicator provides a signal to the duplex valve unit for direct switching to the other filter with a new element.

At the same time, a warning signal is provided to the local overall system controller that one filter element requires replacement.

In general, before switching the duplex valve, an equalising line needs to be activated to avoid excessive pressure peaks when putting the unused filter element into operation.

This solution overcomes the risk of the traditional manual process where correct usage of the equalising line is not guaranteed, according to the company.

Excessive pressure peaks can result in the damage of system components and seals, causing unexpected standstill and maintenance to process equipment.

By using Parker's patented filter elements, the quality of filtration is also safeguarded.

Another solution that will be on show is the company's Icount Mini-Lab, which eliminates the need for laboratory sample testing.

The Icount Mini-Lab has been developed to remove the engineer's reliance on external laboratory services for accurate solid particle contamination analysis of liquids.

Consisting of an Icount bottler sampler (IBS), a laptop computer containing the Parker analysis software with a printer and all the necessary cables mounted in a transportable trolley, the Icount Mini-Lab provides similar accuracy to the sampling carried out in a professional laboratory.

Each device is supplied with 30 Parker oil sample bottles and provides a way for both original equipment manufacturers and end users to monitor contamination in their fluid systems on site.

Testing is carried out in three steps: a hydraulic fluid sample is obtained from the system to be tested; the fluid is sampled for three minutes in the IBS; and the analysis report is printed out immediately.

A three-minute test is normally enough to confirm how contaminated the sample of hydraulic oil is.

The IBS provides onboard, laser-based, particle-counting technology, a three-minute maximum test and an oil contamination report programme in one system.

It features an interactive touch screen, a pressurised bottle chamber via an internal compressor pump, a bottle cavity aperture design, a sample tube cleaning sleeve minimising contamination crossover and an internal printer.

The Icount Mini-Lab is an onsite contamination monitoring solution for engineers and maintenance personnel and provides reproducible results performance to ISO4409:1999 and NAS1638 particle count distributions.

Installing a RAM Clutches Hydraulic Clutch Release - Moment Of Release

With the introduction of the sporty '05 Mustang came something Mustang fans weren't used to-a hydraulic-clutch mechanism. Rather than having a cable connected between the clutch pedal and the fork to release the clutch disc for shifting, the S197 uses hydraulic fluid. This makes the clutch silky smooth but can cause problems in high-performance applications. So, we'll ask, is your transmission grinding and hard to shift under aggressive driving situations? If so, the transmission in your modified S197 Mustang probably isn't broken; it may be in the clutch setup instead.

We wanted to throw that out there because there have been a lot of misdiagnosed transmission problems lately. There's an epidemic in the growing S197 community-grinding gears that are hard to engage and disengage. In our search for a solution, we spoke to Justin Burcham of JPC Racing. "Everybody thinks it's a problem with the clutch or the transmission," he says. "It's actually a problem with the hydraulic clutch-release bearing, which will eventually lead to transmission problems. Ultimately, the synchro rings get beat up." Unfortunately, there's no way of knowing how many cars experience this problem.

RAM Clutches produces a heavy-duty hydraulic clutch release bearing. The piston and cylinder are hard-coated for protection.

The grinding and difficult shifting is due to the hydraulic clutch bearing that's used to control the clutch application (either in or out). The pedal isn't connected mechanically as in previous generations of Mustangs, which utilized a cable that connects the clutch pedal to a fork inside the bellhousing. The new cars feature a hydraulic unit that Ford engineers designed to make the Mustangs easier to drive. Much like the brakes, fluid is used to activate a mechanisim; in this case, the throwout bearing that presses on the pressure plate to control release and engagement of the clutch disc (or discs in a multidisc setup).

Since a clutch upgrade is a popular modification, many S197 Mustangs now have an aftermarket unit. Poor performance can result due to the OEM hydraulic clutch release system. "The car will shift fine under normal driving conditions, and the driver won't notice the issue until the engine is at a high rpm, or when racing or beating on the car," Burcham says. "When the driver goes to put it in gear or shift aggressively, the transmission will grind and, at times, not let the shifter go into gear because the clutch is still engaged.

It also features longer travel than stock: 0.510-0.525 inches compared to the stock setup's 0.430-0.450 inches. RAM says this unit is adjustable and compatible with any single- or dual-disc clutch system.

"The factory release bearing was designed for the OEM pressure plate. When you add an aftermarket clutch, there's an increase in centrifugal clamping force on the pressure plate in order for the clutch to attain a greater holding capacity. Thus, the spring that holds the clutch is stiffer, and in turn, the factory release bearing can't deal with the increased load."

According to Mike Norcia of RAM Clutches, the static clamping pressure of the clutch (at idle and low rpm) isn't that much greater than the stock one. The RAM 11-inch clutch has 2,400 pounds of pressure compared to the stock 11.5-inch unit's 2,250. As the rpm increases, however, the centrifugal force from the levers pushes the pressure-plate ring down harder. This is where the extra grip comes from, in addition to the better clutch disc material. Norcia adds, "The position of the lever in relation to the centerline of its mounting point (called the plane of rotation) is such that the upward angle promotes the lever forcing itself outwards as rpm increases. In addition, the centrifugal pressure isn't linear. It starts out shallow, around 5,000 rpm, and basically goes up by the square of the engine rpm from there. At 7,000 rpm, the pressure curve is at about a 45-degree relative angle. At 10,000 rpm, the line would be shooting almost straight up."

Hydraulic motors limit workplace noise

Noise levels below 58dBA are achievable by using helical gear pumps and compact AC motors.

The Disability Discrimination Act 2005 is putting hydraulic through-floor lifts and step lifts in close proximity to people sleeping and working.

Often the hydraulic noise and vibration levels can be unacceptable, the sources of which are generally the hydraulic pump and motor.

The only solution to date being to house the hydraulics in expensive enclosures.

Hydraproducts new mini hydraulic power pack range has been designed specifically for use in low noise passenger and mobility lifts.

Noise levels below 58dBA are achievable, based on ISO4412 testing, by using helical gear pumps and compact AC motors.

Continuous-contact helical gear pumps minimise pressure ripple, give high efficiencies and quiet operation.

Flow rates are from 8 to 19 litres a minute and continuous pressures up to 275bar Compact AC motors up to 0.75kW have a single-piece body with precision roller bearings.

This gives a smooth drive to the pump, reducing mechanical noise production.

Single acting valves with a low-pressure drop have a diffusing "labyrinth" fitted to ensure smooth lowering minimising aeration, which can cause pump pulsation.

The overall reduction in noise and vibration increases efficiency and life of the hydraulic system.
