Shell to shut in Auger platform to complete tie-in at Cardamom field
With the latest seismic and drilling technologies, the Cardamom development is expected to deliver new production from the deep waters of the Gulf of Mexico to existing infrastructure.
Nearly two decades after setting a world water-depth record for drilling and production, Shell’s Auger tension-leg platform is still playing a central and innovative role in the company’s deep water Gulf of Mexico portfolio – currently producing some 55,000 barrels oil equivalent (boe) per day (Shell share ~30,000 boe per day), and acting in the future as the host platform for the Cardamom subsea development. The Cardamom discovery well also set records three years ago, for subsurface length and depth.
More than a half mile down, Shell is connecting Cardamom wells back to Auger – work that will involve retrofitting the platform and a production shut-in at Auger, which should restart in the fourth quarter of 2013. Once online in 2014, Cardamom (100% Shell share) is expected to produce at a peak rate of 50,000 boe per day.
“The Gulf of Mexico remains an important part of Shell’s portfolio and strategy, and it is expected to generate substantial growth over the next several years,” said John Hollowell, Executive Vice President for Deep Water, Shell Upstream Americas. “Cardamom is a great example of using existing infrastructure to increase oil and gas production in a less capital intensive way.”
In its lifetime, the Auger platform has produced more than 300 million boe.
• The Cardamom discovery is located in Garden Banks Block 427, approximately 362 kilometers (225 miles) south-west of New Orleans, Louisiana, in water more than 800 meters (2,720 feet) deep.
• The completed subsea system will include five well expandable manifolds, a dual 20-centimetre (8-inch) flowline, and eight well umbilicals.
• Modifications to the Auger platform will include additional subsea receiving equipment, upgrade of an existing process train, and weight mitigation which are expected to increase the liquid handling, cooling and production capacities of the host facility.
• Shell used advanced seismic imaging and extended reach drilling to discover Cardamom, and since the discovery, further advancements in seismic have allowed Shell to see beyond a subsurface salt layer to estimate Cardamom’s full resource potential.
• Shell drilled the Cardamom discovery well from the Auger TLP; the well features a measured depth of 9,642 meters (31,634 feet), a horizontal reach of more than 4,570 meters (15,000 feet), and a vertical depth greater than 7,620 meters (25,000 feet).
• The Cardamom exploration well has produced directly from the Auger platform since December, 2010.
