Permian Basin Reports
With the paramount need to preserve
groundwater in a semi-arid region, Permian
wells provide a compelling alternative.
The average basin well produces about
four barrels of water for each barrel of
oil, with the average ratio even higher in
the southern Delaware Basin.
Produced water generation in the nation's
premier oil and gas region has
grown from more than 6 million barrels
a day in 2017 to almost 19 MMbbl/d this
year as operators extend lateral lengths
and intensify hydraulic fracturing to
unlock new hydrocarbon production.
In the northern Delaware in New Mexico,
recycled produced water is expected
to supply most completion water demand
this year. In the Texas portion of the Permian
Basin, recycled produced water
should meet about 45% of operators'
needs, a percentage that continues to grow.
Pushing The Envelope
As demand for produced water recycling
grows, midstream companies will
need to continue pushing the envelope to
expand their capabilities, says Michael
Skarke, chief operating officer of Houston-based
Select Water Solutions.
Last summer, the company achieved
what it considers the largest treated produced
water job recorded in the Midland
Basin, supplying Endeavor Energy Resources
with 300,000 bbl/d over the course
of a month to keep four crews busy on
multiple zipper frac pads.
Altogether, Select pumped 8.2 MMbbl
in 30 days from its Big Spring Recycling
System in Howard County, Tx., to stimulation
jobs in Martin County, Tx., west
of the Big Spring facility.
" We are going to see larger and larger
jobs that will need more and more water, "
Skarke predicts.
Gathering, treating, transporting and
recycling large volumes of water for extended
periods comes with many potential
failure points, but Skarke says these are
manageable. In fact, the project with
Midland-based Endeavor went off without
a hitch.
About nine months before the project's
start, Endeavor approached Select about
supplying up to 10 MMbbl of treated
Last summer, Select Water Solutions achieved the Midland Basin's largest treated
produced water job, supplying Endeavor Energy Resources with 300,000 bbl/d of water
over the course of a month to keep four crews busy on multiple zipper frac pads.
Altogether, the job pumped 8.2 million barrels from Select's Big Spring recycling station
west to hydraulic fracturing sites in Howard County, Tx.
water for stimulation work, says Jason
Jennaro, Select's executive vice president
of water infrastructure.
In response, Select focused on providing
treated produced water from its
existing hub-and-spoke system nine miles
west of Big Spring. Included are produced
water gathering systems accommodating
six large operators within a 10-mile
radius, two 750,000-barrel storage pits
for recycled water and water handling,
and processing tanks and equipment.
The system also connects to Select-operated
saltwater disposal wells.
Two above-ground storage tanks provided
160,000 barrels of buffer storage.
Full automation of gathering, recycling
and distribution allowed complete control
over operations in real time, Jennaro notes.
The setup included five treatment trains
of modular units that utilize dissolved
air flotation technologies to treat up to
60,000 bbl/d apiece in loops for flocculation,
separation and chemical treatment,
Skarke describes.
Using electric pumps instead of diesel
units to improve job sustainability, Select
pushed treated water through a 24-inch,
buried high-density polyethylene pipeline
connecting the Big Spring facility to Endeavor's
development site in Martin County.
A 16-inch line brought produced water
back to the recycling system.
With 14 recycling facilities in the Midland
Basin, Select deployed multiple
chemistries throughout its process, along
with mechanical and physical separation,
Jennaro concludes.
Leveraging Scale
Gravity Water Midstream is piggybacking
on existing saltwater disposal
infrastructure to provide water sourcing,
recycling and disposal services to 40
Midland Basin clients and counting, says
Trace Hight, the company's chief commercial
officer for water midstream.
The Permian-based company, which
also offers power generation and equipment
rental services, connects to about
10 other water midstream players at its
Howard County Super System. The
Howard County system includes 20 connected
SWD wells with about 450,000
bbl/d of permitted disposal capacity,
Hight describes.
To enable recycling, Hight says the
company uses its vast installed water infrastructure
to gather and pretreat water
prior to any final treatment required for
customer operations. Instead of being
transferred to SWD injection pumps, the
volumes slated for reuse are diverted to
storage tanks for processing and treating
that helps prepare them for drilling or
completion operations, he details.
