DENVER, Sep 07, 2011 (BUSINESS WIRE) --
MarkWest Liberty Midstream & Resources, L.L.C., a partnership between
MarkWest Energy Partners, L.P. (NYSE: MWE) and The Energy & Minerals
Group, today announced three critical milestones in the ongoing
development of the hydrocarbon-rich area of the Marcellus Shale. The
first milestone was the announcement today by Sunoco Logistics L.P.
(NYSE: SXL) of the successful completion of the Mariner West open season
and the execution of definitive transportation agreements. Mariner West
is a pipeline project jointly developed by Sunoco and MarkWest Liberty
that will deliver Marcellus ethane to petrochemical markets in Sarnia,
Ontario, Canada. Mariner West will support the long-term development of
more than 1.5 billion cubic feet per day (Bcf/d) of liquids-rich
Marcellus gas in southwest Pennsylvania and northern West Virginia.
The second milestone was the commencement last week of the next phase of
MarkWest Liberty's Houston, Pennsylvania fractionation facility. The
60,000 barrel per day (Bbl/d) Houston facility is the largest natural
gas liquids (NGLs) fractionation, storage, and marketing complex in the
northeast United States and produces high-purity propane, butane, and
natural gasoline for sale into the premium Northeast markets.
The third milestone is MarkWest Liberty's announcement of the
development of up to three large de-ethanizers at its Houston and
Majorsville processing complexes. When combined, the new de-ethanization
facilities could produce in excess of 115,000 Bbl/d of ethane. The first
phase of de-ethanization will have capacity of approximately 75,000
Bbl/d and will commence operation in mid-2013 to coincide with the
start-up of Mariner West.
Since 2008, MarkWest Liberty has invested nearly $1 billion to develop
critical midstream infrastructure to support key producers operating in
the liquids-rich areas of the Marcellus. MarkWest Liberty currently
operates more than 200 miles of natural gas gathering infrastructure and
625 million cubic feet per day of cryogenic processing capacity.
MarkWest's Liberty's processing capacity will increase to nearly 1 Bcf/d
in mid-2012, and MarkWest Liberty is in active discussions with
producers to increase the processing capacity to nearly 2 Bcf/d in early
2014. NGLs recovered at MarkWest Liberty's processing complexes in
southwest Pennsylvania and northern West Virginia will be transported
via pipeline to the Houston complex for fractionation, storage, and
"We are very excited about the successful open season for Mariner West,"
said Frank Semple, Chairman, President and Chief Executive Officer of
MarkWest. "Sunoco Logistics and MarkWest have jointly developed this
critical ethane pipeline project and both companies will provide
significant value to our producer and petrochemical customers. The
successful start-up of the next phase of our Houston fractionator, and
the announcement of the de-ethanization facilities that will supply
ethane to Mariner West, will add significant capabilities to MarkWest
Liberty's existing world-class midstream and NGL infrastructure. The
fractionation and marketing of NGLs is critical to the success of
Marcellus producers and MarkWest Liberty is the leading provider of
integrated NGL transportation, fractionation, storage, and marketing
services in the liquids-rich areas of the Marcellus."
