Oil Companies Race to the Bottom of the Sea

The oil field of the future is taking shape 2 miles undersea. As exploration crews search for new deposits
at ever-greater depths offshore, the industry is grappling with the technical challenges of piping crude and
natural gas through more than 10,000 feet of water. Thats spurring a drive to anchor production
equipment directly to the seafloor, rather than placing it on expensive floating platforms that can be
buffeted by powerful storms.
Professors at the University of Houston, which this fall will launch a graduate program in subsea
engineering, envision an underwater oil city overseen by swimming robots. Subsea engineering is like a
new frontier, says Matthew Franchek, whos heading the program. We can at least walk on the moon.Youre not walking in subsea.
Its a vision that could become a reality within six years, says Tore Halvorsen, senior vice president for
subsea technologies at FMC Technologies (FTI). Companies realize that to bring down operating costs,
they have to do something drastic, he says. FMC and others are designing equipment that can withstand
depths of 10,000 feet or more, where temperatures drop to just a few degrees above freezing and pressures
are 300 times greater than at the surface. Spending on subsea valves, pipelines, cables, and other gear will
reach a record $13.8 billion in 2013, a 65 percent jump from last year, according to research consultant
Quest Offshore Resources.
Energy companies would save billions of dollars and extract more oil from their wells if they could
operate more efficiently in ultradeep water. For starters, there would be no downtime from weatherdisruptions. Last Augusts Tropical Storm Isaac forced the evacuation of 499 offshore oil and gas
production platforms in the Gulf of Mexico, costing companies about 5.8 million barrels of lost output.

says a 1 percent improvement in oil recovery translates into a $3.2 billion increase in the value of some
projects.
Since 1961, when Royal Dutch Shell (RDS/A) first figured out how to place the wells pressure-control
valves directly on the seabed, the industry has been working to untether other equipment from the
production platform. In current setups, cables and electrical lines snake up to the surface. Long strings of
pipes, called risers, carry the oil, which is often mixed with natural gas, up to floating production vessels
the length of three American football fields, where workers and machinery separate, clean, and processthe oil, gas, and water. Oil is loaded onto tankers, and gas is sent back down to the seafloor and pushed
through pipelines to the shore, while water is discarded.
Moving all of those operations to the seafloor would eliminate some of that up and down travel through
the ocean, says FMCs Halvorsen. The company has booked $4.6 billion in future orders of subsea
equipment and projects an additional $2.5 billion in revenue from installation, maintenance, and other
services. Oil producers could do away with the massive, floating platforms that can cost as much as
$1 billion to build or purchase. Without the need to ferry workers by helicopter to offshore sites and house
and feed them there, operating costs would drop.
To build the integrated system the industry envisions, a network of remote monitoring sensors will be
needed to transmit data and instructions between the surface and seafloor. Swimming robots, which are
now tethered to ships on the surface, will monitor the equipment and perform maintenance, while a new
offshore electrical grid will power the submarine operations.
Schlumberger (SLB) and Cameron International (CAM) last year announced the creation of a venture
called OneSubsea that blends the formers expertise in oilfield services with the latters mechanical
knowledge of valves, pumps, and other gear. OneSubsea CEO John Carne says the partners are working
on a technology to boost recovery that tracks and controls the flow of oil as it journeys from the pores of
underground rock miles underwater to the surface. Other than having essentially mechanical
hardwaredumb ironon the seabed, which is just turned on and off, which is really what happens
today, you need to be able to control that, influence it, and manage that in real time, he says. The
technology exists today. Its just that its not brought together in one beautiful system.
Siemens (SI) is assembling an underwater grid that will include onshore generation plants running as
much as 100 megawatts of electricity through power lines along the seafloor to the oil fields. It should be
ready by the end of next year, says Adil Toubia, head of Siemenss oil and gas business. Well be the
engine to drive this, he says.
The world got to see submarine robots in action three years ago, during BPs (BP) oil spill in the Gulf of
Mexico, when remote-control vehicles were dispatched to troubleshoot the broken machinery of theMacondo well 5,000 feet underwater. The next generation will have to be far more advanced, with better
sensors, gauges, and programming, to enable them to evaluate and respond to their surroundings, says
Larry Madin, director of research at Woods Hole Oceanographic Institution. Shell is developing flying
nodes, essentially tiny aquatic drones. Powered by batteries and guided by GPS, schools of nodes will
swim down and collect seismic data on the seafloor that will be used to generate better images of the
underground oil reservoir.
Subsea development is still in the middle innings, says Stephen Trauber, vice chairman and global head
of energy at Citigroup (C). Its huge and expected to stay strong.
The bottom line: Spending on subsea gear will hit $13.8 billion this year, spurred by the industrys drive
to boost offshore production.
