“Green Dogs” take up with the “Hunt Dogs”

Lawmakers line up against governor’s forest leasing plan
Monday, February 22, 2010
By Don Hopey, Pittsburgh Post-Gazette

A caucus of 37 “green dog” and “hunting dog” legislators is barking mad about a Rendell administration budget proposal that would seek to raise $180 million by leasing more state forest land for Marcellus shale gas well drilling…. In a Feb. 3 letter to the governor, the legislators called for a moratorium on state forest land leasing until the “long-term environmental, fiscal, economic and social impacts” are studied and reviewed and requested a meeting with the governor on the issue….

Refracking wells?

In an Q and A interview in the Williamsport Gaurdian, Richard Adams , a spokesman for Chief Oil and Gas said—
“Re-fracking is not a common event in the Barnett or any other shale field at this time and I would not expect it to be common in the Marcellus at any point in the future.”

If this were true, it would be a good thing.

If a well is only fracked once, then the number of fracks would equal the number of wells but if wells are refracked every few years the number of fracks grows exponentially larger than the well count.
Each refrack uses more water than the last, 25% more is the given figure.  Each refrack generates a new load of highly contaminated waste water. Each refrack restresses the well casings with 6000 to 8000 pounds per square inch of pressure.  Each refrack invites the danger of surface contamination by spilled or leaked concentrated chemicals.

When some folks in the Barnett Shale area of Texas were asked if Adam’s statement was true they gave these replies.

“Baloney!  I don’t have time to find references now but they are available. They don’t have to get a permit so no one really keeps track but it’s common knowledge.”

“Chk (Chesapeake) has told folks they plan to refrack many times over the life of the reserves..like every 3 or 4 years.”

“If they are on the lease side trying to say you will make lots of money…,and they refrack When they are talking about the environmental side, they say the opposite.”

“FALSE.  One of the pad sites near my home is refracked regularly due to several wells on the site. The frack trucks are also a common site on the highway. Ubiquitous is the word.”

“Absolutely they will refrack  and have already at many wells. The Industry folks I talked to relayed the probability of  every 3 to 5 years  depending on the well.”
And here’s what the industry has to say about it.

“It has been established that only 10% of GIP [gas in place] is recovered with the initial completion. Refracturing the shale can increase the recovery rate by an additional 8% to 10%. Simple reperforation of the original interval and pumping a job volume at least 25% larger than the previous frack has produced positive results in vertical shale wells.”

According to Halliburton, an oil and gas service company:
It is important to note that a well drilled in the Marcellus shale may have to be fracked several times over the course of its life to keep the gas flowing, and that each fracking operation may require more water than the previous one.

From a Devon investor report: (Devon is one of the major gas exploration companies in the Barnett shale)

In addition to the refracs, we have also drilled and completed several wells on 250-foot spacing rather than the 500-foot spacing that our existing proved reserves are based on. If the early success of the first several wells drilled on 250-foot spacing continues, there may be substantial additional reserves to be recognized in the Barnett Shale over the coming years.

Our gas drilling in the Barnett Shale and Selma Chalk continues to provide additional production and reserves as we continue to test the limits of each field, whether it is from down spacing, extending the limits of each field or refracking of existing wells. (emphasis added)

As an example of a successful refrac, Devon Energy has reported on a well from which production had declined from 2,000 mcfe/day to 500 mcfe/day after 4.5 years. A re-frac restored production to 1,600 mcfe/day initially, declining to 1,000 mcfe/day after 3 months, and has probably doubled the remaining reserves from this well.
I suppose this information speaks for itself.

Marcellus Shale Coalition Releases the Facts on Flowback Water Treatment

CANONSBURG, Pa., Feb. 4 /PRNewswire/ — The Marcellus Shale Coalition today issued the following statement to provide the facts regarding water use and flowback water management in the development of natural gas from the Marcellus formation: “Pennsylvanians deserve to get the facts about water management for Marcellus Shale development.  We need to put an end to the suppositions that could threaten our state’s ability to create jobs and investment here at home. “Regulations governing the use and management of water needed to drill a Marcellus Shale well in Pennsylvania are among the most stringent in the nation, and ensure the protection of the Commonwealth’s water resources.  Water withdrawals from streams and rivers must be approved, including the withdrawal location and amount of water required for each well, as well as detailed storage and treatment plans. …

Some might ask how stringent are the regulations, and are they stringent enough. One of the regulatory agency representatives at a recent Marcellus Shale public meeting, said federal regulations are stronger than those in PA, but the feds only regulate a small portion of gas industry activities.

“The industry currently treats or recycles all of its flowback water. Recycling accounts for approximately 60 percent of the water used to complete Marcellus Shale wells, with greater percentages predicted for the future.  There are more than a dozen approved water treatment facilities available to treat flowback water, with plans for additional capacity in the future …

Some might ask what the nature of the treated or recycled end product actually is. How much of the original toxic materials and total dissolved solids (TDS) are removed by the treatment, and are ALL the permitted treatment facilities producing the same end product before discharge? Are some discharging only partly treated – or even untreated – fluid?  Is discharging any of the treated fluid into a waterway, injecting it deep into an abandoned well or burying it in a landfill environmentally benign and of no risk to public health? Also, given the number of wells currently producing flowback fluid, is a dozen treatment facilities adequate to protect the environment and public health?

“Claims about elevated levels of Total Dissolved Solids (TDS) in the Monongahela River from natural gas development have been refuted by studies that attribute a minimal amount of the total TDS levels to Marcellus Shale drilling activity. In fact, historical monitoring shows the variability of TDS levels in the Monongahela and other rivers to be a cyclical phenomenon over the past 30 years. …
Some might say that TDS is a scientifically-established environmental pollutant, known to damage freshwater aquatic organisms, endanger public health, interfere with potable water supplier’s services and with industries using water. They might ask whether adding more TDS to the Monongahela – or to any waterway – makes sense, regardless of whether the TDS comes from gas drilling activities or from some other source.
