Royal Dutch Shell said Tuesday that it made a gas discovery at its deepwater Marjoram-1 well in Block SK318, its second find in the block.
The well is located about 111 miles (180 kilometers) off the western coast of Malaysia in 497 feet (800 meters) of water.
Details about size of the gas column weren’t disclosed.
In April, Shell made a gas discovery at its Rosmari-1 miles, also located in Block SK318.
“Our strategy to expand our heartland areas through technologically advanced exploration is delivering tangible success in deep-water in Malaysia,” Shell Upstream International Director Andrew Brown said.
The block is located in the South China Sea.
The Energy Information Association estimates that there are about 11 billion barrels of oil reserves and 190 trillion cubic feet of natural gas proved and probable reserves in the South China Sea.
Shell operates and owns an 85 percent interest in the block. Malaysia’s Petronas holds a 15 percent stake.
