Shell's massive Appomattox hull begins voyage to Texas

The massive four-column hull of a deep-water oil platform began sailing from South Korea to Texas this week, starting a months-long voyage that will bring Shell closer to finishing a multibillion-dollar Gulf of Mexico project.

The departure is the latest milestone for a gigantic venture the European company sanctioned two years ago in the face of a raging oil bust that forced many of its rivals to scuttle offshore plans.

As oil prices tumbled, Shell spent $600 million and employed 1,500 workers in Texas and Louisiana alone to fabricate parts for the so-called Appomattox project, expected to start pumping oil 80 miles off Louisiana by the end of the decade. Even so, Shell says it could still wring a profit from its 125,000-ton platform with oil prices below $50 a barrel, after deep cost cutting.

"If you look at the platforms, we used to have a lot more focus on the deeper, the bigger," said Wael Sawan, executive vice president of deepwater at Shell, in a recent interview. "Much of our technology spend is now geared toward more capital efficiency, lower costs."

Shell said it has whittled down expenses on the Appomattox by more than 20 percent, as it cut down on the time it needed to drill wells and took advantage of lower equipment prices. The company used new high-tech rigs to drill faster, and it closely monitored every step to slash non-productive time.

The project is located in the Gulf of Mexico’s deep Norphlet geologic trend, where Shell is currently the first to achieve commercial discoveries.

The Appomattox project will consist of a semi-submersible, four-column production host platform, a subsea system featuring six drill centers, 15 producing wells, and five water injection wells.

...The deepwater fields are owned by Shell (79%) and its partner Nexen Petroleum Offshore (21%), a wholly owned subsidiary of CNOOC. Peak production from the fields is estimated to be approximately 175,000 barrels of oil equivalent (boe) a day.

The Appomatox field was discovered in March 2010 by drilling the discovery well at Mississippi Canyon block 392. The well was drilled to a depth of 7,643m (25,077ft) and encountered approximately 162m (530ft) of oil pay.It was followed by drilling an appraisal sidetrack well that same year to a depth of 7,910m (25,950ft), which encountered approximately 116m (380ft) of oil pay. The field was further appraised in February 2012 by drilling an appraisal well in Mississippi Canyon block 348, at a water depth of approximately 7,257ft and to a total depth of 25,851ft. The well encountered approximately 150ft of oil pay.

The Vicksburg field was discovered in July 2013 by a discovery well at Mississippi Canyon Block 393 that was drilled at a water depth of 2,269m (7,446ft), to a total depth of 8,042m (26,385ft). The discovery well encountered more than 152m (500ft) of net oil pay.

The two fields are together estimated to hold recoverable reserves amounting to 650 million barrels of oil equivalent (MMboe) approximately....

Shell to build its largest Gulf of Mexico platform for Appomattox development

July 1, 2015

...During design work for Appomattox, Shell reduced the total project cost by 20% through supply chain savings, design improvements, and by reducing the number of wells required for the development, the company has said.  This includes advancements from previous four-column hosts, such as the Olympus tension-leg platform (TLP), as well as ensuring a high degree of design maturity before construction.

With these and other cost reductions, the go-forward project breakeven price is estimated to be around $55 per barrel Brent equivalent, the company added....

what my fear is that Shell will also trim costs by drilling fewer wells, so the ultimate recovery will be less than it could be.

Those reserves will likely be lost forever.
