Alcoa Oil & Gas, an Alcoa business, will supply 5,300 meters (17,400 feet) of Aluminum Alloy Drill Pipe (AADP®) to Fugro McClelland Marine Geosciences of Houston and Fugro Singapore PTE, LTD for use in offshore geotechnical survey drilling projects. Fugro McClelland Marine Geosciences is a world leader in marine geophysics and seafloor mapping in support of resource development, engineering and scientific projects.
Fugro will use Alcoa’s 5-inch diameter AADP® for global, offshore, geotechnical surveys in water depths ranging up to 3,000 meters (1.8 miles). These surveys are a critical first step in determining whether a site is geologically suitable for a particular application, such as construction of offshore oil and gas drilling or production platforms. Alcoa’s drill pipe is composed of high-strength, aluminum alloy tube connected by a proprietary thermal joining technology, which enables conventional steel tool joints to be used with an aluminum alloy pipe body. This innovative coupling of aluminum and steel provides a strong yet lightweight solution for deep water drilling resulting in increased cost efficiencies.
“We decided to use Alcoa Aluminum Alloy Drill Pipe because it is approximately half the weight of steel, allowing us to double our offshore operating depth,” said Ken Taylor, Operations Manager, Fugro McClelland. “Another factor in our decision was Alcoa’s status as a worldwide leader in aluminum, which can support our efforts with advanced metallurgical technology and innovation.”
Alcoa produces the aluminum tubes at its Lafayette, Indiana, facility.
“Fugro’s decision to use Alcoa’s AADP for such a critical application is a testament to our core value proposition, which is to extend the drilling range of existing assets,” said Jay Grissom, Marketing Director of Alcoa Oil & Gas.
Alcoa’s AADP® was also successfully used in complicated deep water drilling applications by Brunei Shell Petroleum Co. Sdn. Bhd., offshore Seria, Brunei, to a total depth of 7,485 meters (4.6 miles) in about 60 meters (197 feet) of water.

Dec 13, 2012 – Norwegian oil major Statoil announced Thursday that it plans to use seismic cables on the seabed to help produce 30 million additional barrels of oil from its Snorre and Grane fields. The company has signed contracts worth $160 million with U.S. firm Geospace Technologies to deliver the cables, which will be part of a permanent reservoir monitoring (PRM) program. Statoil believes the technology will allow it to better understand the reservoirs because they are stable and able to provide a more accurate picture of the subsurface than cables that are towed on the surface and which are subjected to wind, waves and currents. Statoil plans to lay more than 400 miles of seismic cables. Statoil currently recovers around 50 percent of the oil from its operated fields on the Norwegian continental shelf.
