is the oxygen of oil companies. Success and survival depend on tilting the risk in the company’s favour. In January 1996, Jack Golden told John Browne that BP’s explorers had understood the lessons of Sycamore and the salt. The corporation, he urged, should make the leap. His team calculated that, rather than their rivals’ estimates of 10 billion barrels of oil within the rocks below the Gulf, there were probably 40 billion barrels. In the second round of bidding for ten-year leases in the Gulf, BP should outbid Shell and Chevron. Browne agreed: the company would buy more acreage in ultra-deep water than any of its rivals.
The investment coincided with the industry’s slide towards disaster. 1998 was a dog year in the oil trade. The price of oil slumped below $10 a barrel, the lowest in 50 years. There was surplus of production, and cut-price petrol was being sold across America and western Europe. The protection enjoyed by vested interests was crumbling. Thousands of experienced engineers were fired, rigs lay unused or could be hired for 25 per cent of the old rates, and bankruptcies ravaged the industry. ‘I can’t tell you absolutely this is the bottom, but we haven’t seen anything like this,’ admitted Wayne Allen, the chairman of Phillips Petroleum. Potentially, the only profitable activity was deep-water drilling in the Gulf of Mexico, but hiring rigs to drill to a new record 7,625 feet below the sea bed and bore down to 12,000 feet cost $200,000 a day. New rigs were being designed to moor in over 10,000 feet of water and drill nearly 30,000 feet into the rock. The 3D image of Block 778 suggested there was oil somewhere four miles below the sea bed. A test bore in Block 778 would cost $100 million. The unanswered question was, where precisely to drill a 12-inch hole four miles through the rock?
At first, the debate among the 13 explorers was sterile. Red dots from lasers darted around the screen, identifying strengths and weaknesses for the drill’s path. At last the discussion became animated, and a route was chosen. The privilege of naming Block 778 was given to Cindy Yeilding, an attractive blonde geologist – an unusual sight in a male-dominated world. Having a passion for Neil Young’s music, she chose ‘Crazy Horse’, the name of his band. Protests soon arrived from the Sioux Indians, defending the memory of their chief, so the plot was renamed ‘Thunder Horse’.
On 1 January 1999, Rainey and Yeilding sat in a bland, windowless second-floor office, dramatically named the ‘Operations Room’, following the progress of a computer-guided drill gouging 29,000 feet through silt and salt towards the porous sandstone and shale where they believed oil had been trapped for eight million years. Only two rigs in the world were able to drill to such depths. Fortunately one of them, Discoverer 534, had already been hired by Amoco, which had just been bought by BP. The cost was $291,000 per day. Reservoir engineers had produced a computer programme to steer the bit around perilous flaws, after which it was hoped that oil would gush through the metal casing to the surface. Several drill bits were broken and replaced, but the geologist on the rig reported that the rocks brought up from the depths were the right age. ‘We’re at 13.6 million years,’ he told Houston, hoping that fossils 14.7 million years old, indicating the possible presence of oil reserves, would soon appear. In real time, Rainey and Yeilding scrutinised the constantly changing numbers flashing on a bank of screens for evidence of oil. One sensor attached to the drill reported whether gamma rays detected clay – a negative reading indicated oil. Another sensor measured resistance to electricity – a positive reading indicated oil and gas, because neither conducts electricity. For the next 186 days other members of the team followed the drill’s progress on their laptops, at Starbucks or in their beds at night.
‘Our sandbox has just got bigger,’ Rainey exclaimed on 4 July, as the drill’s sensors reported oil. Nine months later, the size of the reservoir was confirmed: one billion barrels of oil, the biggest ever discovery in the Gulf of Mexico. ‘The prize was beneath the salt,’ said Rainey, ordering everyone to secrecy until all the neighbouring acreage had been signed up by BP. After weeks of around-the-clock work, the explorers and their families discreetly celebrated their success with champagne and dinner.
Around Houston, BP’s triumph was greeted with mixed emotions. In normal times, the city fathers would have been thrilled. More oil would mean a boom, but at $10 a barrel, that was not going to happen. The American public, seemingly prepared to pay more for a bottle of water than for a gallon of petrol, were manifestly ungrateful for any Big Oil success. Unaware of the technological achievements involved, the oil industry was taken for granted by a generation of Americans who had grown up regarding cheap gasoline as their God-given birthright. Filling their petrol tank did not make anyone feel good. Ever since nearly 11 million gallons of oil had spilled from the tanker the Exxon Valdez into Alaska’s pristine waters in March 1989, the public’s antagonism towards Big Oil had become entrenched. Big Oil had overtaken Big Tobacco as a focus of hatred. Within the American public’s DNA was a belief that oil was a decrepit rust industry unfairly extracting tax from honest citizens. Few appreciated that Thunder Horse would fractionally reduce America’s dependence on imported oil, which provided 60 per cent of its daily consumption. ‘Guns, God and Gasoline’ may have represented freedom for many Americans, yet the oil companies, apparently ambitious for ever more power while remaining unresponsive to the public, were neither understood nor trusted.
In that hostile environment, BP’s achievement was acknowledged only by its rivals. The company’s reputation had been soaring since 2000 because of aggressive acquisitions. Exxon, Shell and Chevron anticipated their own successes, although the timing was uncertain. While the kingdoms of the major oil companies were diminishing, BP, the largest oil producer in America, was more admired than hated. David Rainey was proud to have met the architect of that success, BP’s chief executive John Browne.
As the guest of honour at a packed dinner in Houston in August 2002, Browne had been hailed as a hero. BP’s dapper chief executive, regarded as an idealist and a maverick, was loudly applauded for describing the Gulf as the ‘central element’ of BP’s growth. No one in his audience underestimated BP’s importance. The company had become the Gulf’s largest acreage-holder, and owned a third of all the oil discovered there. In the oil business, strong personalities made the difference, and Browne, like an evangelist, was wooing his audience. ‘We’re going to spend $15 billion here over the next decade,’ he promised, ‘drilling between four and seven wells every year.’ His enthusiasm was understandable. Oil which had been inaccessible in 1998 was now, he knew from Rainey, within their grasp. If the Houston team was successful, BP would outdistance its competitors. Only a handful of doubters suspected that Browne loved being treated like a rock star more than he loved rocks and their contents. Older members of his audience knew that oil had always attracted the ambitious and the larger than life. The same man who controlled 90,000 employees and pledged to serve mankind could also behave unaccountably. That was the nature of multinationals.
Exploration for new oil had barely increased over recent years. Since the mid-1970s, over 1,800 new wells in the Gulf of Mexico and in the Atlantic Ocean off Brazil, Angola and Nigeria had promised to deliver 47 billion barrels of oil. But, like a herd, the major oil companies assumed that prices would not rise, and feared risking their profits and their share prices. Their investment in the search for more oil was cut, and many wells had been abandoned. Yet, on reflection, Thunder Horse was recognised as marking a small revolution, and formerly abandoned areas were reconsidered. ‘Elephants’ meant big, fast profits. Thunder Horse meant there was at least another 100 billion barrels of oil to be found under the sea in the Gulf and the Atlantic. Those who believed oil supplies would ‘peak’ between 2011 and 2013 were challenged to reconsider their doom-mongering predictions. The only disadvantage was the cost. Convinced that oil would not rise above $30 a barrel, Browne congratulated himself that his sharp reduction of BP’s costs would ensure Thunder Horse’s profitability.
Positioning the Korean-built steel rig 6,050 feet above a small hole in the sea bed caused jubilation among BP’s beleaguered staff. ‘The serial number of each piece of equipment is 001,’ exclaimed Rainey with pride. No one on the platform expected to actually see oil. Gushers of crude soaring into the air were relics of history. Oil produced in the Gulf was diverted as it emerged from wells into the Mardi Gras system, a network of about 25,000 miles of pipelines criss-crossing the sea bed from Texas to Florida. BP’s task was to link Thunder Horse to the system. The obstacles were the depth and distance
