COSL sees earnings jump 17pc in first quarter
China Oilfield Services attributes improved results to higher drilling demand

China Oilfield Services Ltd, the nation's dominant oil and gas drilling services provider, posted a 17 per cent rise in first-quarter net profit on the back of higher drilling volume.
Net profit for the three months to March was 1.41 billion yuan (HK$1.74 billion), compared with 1.2 billion yuan in the same period last year.
The first-quarter gain is 19.3 per cent of the 7.32 billion yuan average full-year profit estimate of 28 analysts polled by Bloomberg.
The company made a net profit of 6.72 billion yuan last year.
Revenue rose 18 per cent in the first quarter to 6.75 billion yuan as the state-backed firm ramped up drilling capacity.
It added a new rig during the period, while four rigs commissioned last year also contributed to growth.
The total operating days of its rigs rose 5.6 per cent to 3,061.
