The Stones field, located 200 miles southwest of New Orleans in the Gulf of Mexico, is ultra deepwater discovery that’s spurred unprecedented innovation.
Stones is officially the world’s deepest oil and gas project and began producing in September 2016, through subsea infrastructure beneath 9,500 feet of water.
Shell Stones Oil Field
Shell announced the final investment decision to develop the Stones field in May 2013. Work then began to construct and fabricate the floating production, storage and offloading (FPSO) vessel and subsea infrastructure. The FPSO, called Turritella, set sail from the shipyard in Singapore in October 2015 and arrived in the Gulf of Mexico in January 2016.
Development of the Stones field began with two subsea production wells tied back to Turritella. Six further production wells will be added later, as well as a multi-phase system to pump oil and gas from the seabed to the FPSO, increasing recoverable volumes and production rates.
All eight wells will be connected to Turritella. The reservoir depth is around 8,077 metres (26,500 feet) below sea level, and 5,181 metres (17,000 feet) below the mud line.
