\n<\/div>\nTotal SA<\/span>\u2019s discovery of South Africa\u2019s first oil in deep water could prove to be a bonanza for a country lacking crude reserves of its own and prompt a rush from other majors. <\/span><\/span><\/p>\n That\u2019s if they\u2019re able to solve the engineering challenges of operating in one of the fastest ocean currents in the world.<\/span><\/span><\/p>\n <\/p>\n The Brulpadda find, with reserves estimated at about 1 billion barrels of oil, is located in deep waters around 175 kilometers from South Africa\u2019s coastline. It could be enough to supply South Africa\u2019s refineries for almost four years and be a major boost for the country\u2019s struggling economy.<\/span><\/p>\n But the prospect is surrounded by the Agulhas Current, a fast-moving flow of warm water where the Atlantic and Indian oceans converge, which travels the country\u2019s east coast and can cause waves the height of a multistory building. Total says it\u2019s found solutions to the problems, but not every explorer has the financial resources or harsh-environment experience of the French oil major.<\/span><\/p>\n <\/p>\n When Total returned for a second attempt in December, with the Deepsea Stavanger rig to finish a well, it employed previously unused engineering techniques. While rigs are usually carefully stabilized in the water by thrusters as drilling takes place, Total further secured the platform with a tug boat to provide support.<\/p>\n Rough Environment<\/span><\/b><\/span><\/p>\n Total had to cancel an initial drilling attempt in 2014. The highly anticipated attempt had to be abandoned because of mechanical failures caused by the rough environment.<\/span><\/span><\/p>\n <\/p>\n The first try lasted a few months and cost about $190 million, according to Dave van der Spuy, resource evaluation manager at Petroleum Agency South Africa, which promotes exploration for the South African government.<\/span><\/p>\n The French oil major cited repairs<\/span> needed to the Eirik Raude rig, and its commitment to another contract, as reasons for suspending activity.<\/span><\/span><\/p>\n While the North Sea is harsh, at least it\u2019s predictable, said Adewale Fayemi, general manager for Total E&P South Africa. \u201cHere in South Africa, waves and currents are most of the time in opposite directions, which generates very bad seas and the wind can be very high and changes direction.\u201d<\/span><\/p>\n <\/p>\n Second Attempt<\/span><\/b><\/span><\/p>\n The second time around, Total also used onshore high-frequency radar to keep ahead of the Agulhas Current, Fayemi said. It also used a simplified riser system, which is a pipe that connects an offshore production structure on the water\u2019s surface to sub-sea facilities that could be accessed and repaired on location, specifically to avoid problems which ended the team\u2019s effort four years earlier.<\/span><\/span><\/p>\n \u201cTotal deployed a suitable rig for the operation and a sophisticated weather forecasting system, coupled with the presence of an on-site specialist, in order to more accurately assess prevailing weather and ocean conditions,\u201d Fayemi said.<\/span><\/span><\/p>\n <\/p>\n The second attempt also took less time and was cheaper, costing about $160 million, according to Van der Spuy. \u201cIt\u2019s an incredible achievement in terms of engineering and in terms of taking a risk.\u201d<\/span><\/span><\/p>\n Total plans to acquire 3-D seismic for the license this year, to help determine its next prospects there, which it plans to follow up with as many as four exploration wells<\/span><\/span><\/p>\n \u00a0<\/p>\n<\/div>\n![\"\"](\"https:\/\/cdn.ghanamma.com\/2019\/03\/4239407115201_4933841148236.JPG\")
