Europe/Africa Jackup Rigs Third quarter 2007 revenues for the Europe/Africa jackup rigs increased by $39.1 million, or 29%, as compared to the prior year quarter. The increase in revenues was primarily due to the addition of ENSCO 105 to the Europe/Africa jackup fleet in the first quarter of 2007, which provided $22.8 million of revenue in the current quarter, and to a 29% increase in average day rates. The increase was partially offset by a decrease in utilization to 90% in 2007 from 100% in 2006. The improvement in average day rates was attributable to improved demand resulting from increased spending by oil and gas companies. The decrease in utilization primarily was attributable to the mobilization of ENSCO 100 from Nigeria to the North Sea, which commenced in late August of 2007. Contract drilling expense increased by $16.2 million, or 40%, from the prior year quarter due primarily to the relocation of ENSCO 105 to the region, which resulted in an additional $7.4 million of expense in the current quarter, and to increased personnel costs, repair and maintenance expense and costs associated with the departure of ENSCO 100 from Nigeria, all of which were partially offset by a reduction in mobilization expense during the quarter. For the nine months ended September 30, 2007, revenues for the Europe/Africa jackup rigs increased by $134.6 million, or 37%, from the prior year period. The increase in revenues was primarily attributable to the addition of ENSCO 105 to the Europe/Africa jackup fleet in the first quarter of 2007, which provided $32.7 million of revenue in the current year period, and to a 33% increase in average day rates. The increase was partially offset by a decrease in utilization to 95% in 2007 from 100% in 2006 due primarily to the mobilization of ENSCO 100 as noted above. The improvement in average day rates was attributable to improved demand resulting from increased spending by oil and gas companies. Contract drilling expense increased by $41.8 million, or 36%, from the prior year period due to the relocation of ENSCO 105, which resulted in an additional $14.0 million of expense during the current year period, and to increased personnel costs, reimbursable expenses, repair and maintenance expense and costs associated with the departure of ENSCO 100 from Nigeria, all of which were partially offset by a reduction in mobilization expense during the period. North and South America Jackup Rigs Third quarter 2007 revenues for the North and South America jackup rigs decreased by $57.2 million, or 32%, compared to the prior year quarter. The decrease in revenues was partially due to the reduced size of the North and South America jackup fleet as two rigs were relocated from the Gulf of Mexico during the first quarter of 2007 and the third quarter of 2006. The two jackup rigs provided $17.1 million of revenue during the third quarter of 2006. The decrease in revenues also was due to a decrease in utilization to 78% in 2007 from 93% in 2006 and to an 11% decrease in average day rates compared to the prior year quarter. The decrease in utilization and average day rates was primarily attributable to a decrease in demand by oil and gas companies as they have reduced spending on shallow water drilling in this region. The decrease in utilization also resulted from an increase in the amount of time rigs spent in shipyards during the current year quarter as compared to the prior year quarter. Third quarter 2007 contract drilling expense increased by $900,000, or 2%, compared to the prior year quarter. The increase in contract drilling expense resulted from increased personnel costs and repair and maintenance expense partially offset by the reduction in fleet size. For the nine months ended September 30, 2007, revenues for the North and South America jackup rigs decreased by $122.5 million, or 24%, compared to the prior year period. The decrease in revenues was partially due to the two relocated rigs as noted above, which provided $55.8 million of revenue in the prior year period. An 8% decrease in average day rates and a decrease in utilization to 82% in 2007 from 90% in 2006 also contributed to the reduction in revenue from the prior year period. The decrease in utilization and average day rates is due to a decrease in demand by oil and gas companies as noted above. For the nine months ended September 30, 2007, contract drilling expense increased by $7.7 million, or 6%, compared to the prior year period. The increase in contract drilling expense was primarily attributable to increased personnel, insurance, and repair and maintenance expense, partially offset by the reduced size of the fleet. |
