DUSHORE,
PA - The Department of Environmental Protection is investigating two
methane migration incidents near Chesapeake Energy drilling operations
in Forks Township, Sullivan County. One incident occurred in the Black
Creek area, and the other near Pleasant Valley Road.
Although
DEP has not yet determined the cause of either methane migration, an
abandoned well from the 1950's was discovered around a mile northwest
of the Pleasant Valley Road problem area.
DEP
detected combustible gas at the surface of the ground above the
abandoned BJ Broschart well in Forks Township. A township resident
reported to RDA that the well was drilled to a depth of 7,000' and never
put into production.
"Since
the well is considered an orphaned well, with no viable operator, the
department assumed the responsibility of plugging the well through the
Orphaned Well Plugging Fund," said Spadoni.

DEP hired Hydrocarbon Well Services to plug the orphaned well through an emergency contract.
"Had we
not taken this action, this well would have simply been added to a list
of thousands of orphaned wells waiting to be plugged, and it could
have taken many years," said Spadoni.
"We
first became aware of the [Pleasant Valley Road] situation through a
report form Chesapeake, after the company received a complaint from a
resident," said DEP's Community Relations Coordinator Dan Spadoni in an
email. "The initial investigation led to the temporary evacuation of
the resident due to elevated levels of methane in the basement of the
home."

Vents and alarms were installed so that the resident could return to the property.
"Screening
and further investigation in the area identified several other water
supplies, including that of the complainant, with elevated levels of
methane," said Spadoni.
According
to DEP, there were no obvious problems with Chesapeake's nearby
Lambert Farms well that would have contributed to the methane
migration.
"[That's] why there is no specific violation in our compliance system," said Spadoni.
The
other methane migration occurred in the Black Creek area of Forks
Township, which is about 4 miles away from the BJ Broschart well.
"There
is one potentially impacted water supply as well as surface expressions
of methane in the creek. The nearest gas wells to this occurrence are
Chesapeake's Black Creek and Insinger wells," said Spadoni. "Again,
there are no obvious problems relating to the construction of these gas
wells, which is why there are no specific violations noted."
As drilling activity increases in the Marcellus Shale region, so do the risks posed by abandoned wells.
"When
new gas wells are drilled near abandoned wells, the abandoned wells
present an increased risk of gas migration," said Laurie Barr of Save
Our Streams PA. "Unplugged wells can provide pathways between formation
layers and the surface.
"Safety
issues arise when abandoned wells are located within close proximity to
active drilling," said Barr. "In McKean County a home exploded. The
DEP subsequently ordered the operator to plug three abandoned wells
that were discovered during the investigation into the house
explosion."
When
asked to comment, Sullivan County resident and gas industry watchdog
John Trallo said, "Not only is the DEP unwilling to hold the industry
responsible, it seems like they go out of their way to actually cover
up for them without investigation.
The lack
of information and transparency by DEP about the these kind of
situations leaves the public in the dark as to just how often they are
occurring - something you would think would be helpful in analyzing the
safety of shale gas development."
RDA
would like to know if there are other abandoned wells in the areas of
Sullivan County where shale gas drilling has occurred or will occur. At
a meeting at Chesapeake event at Sullivan's Elkland Township Fire Hall
this summer, RDA Board President Ralph Kisberg asked a Chesapeake
representative if they knew of any abandoned gas wells in the county.
Kisberg also suggested Chesapeake involve the community in researching
old newspapers, county records and family documents and make a PR event
out of the project.
When
Chesapeake's Andy Travis was asked if they had ever drilled into an
abandoned well in the area, Travis truthfully answered no. Perhaps a
better phrasing of the question would have yielded a different answer:
has hydraulic fracturing of a Chesapeake well ever caused communication
with an abandoned well?
