COSL Q2 Profit Jumps 12% on Robust Offshore Drilling Demand
China Oilfield Services Limited (COSL) reported second-quarter 2026 net profit of RMB 1.85 billion ($260 million), a 12% increase year-over-year, driven by strong demand for offshore drilling services and higher utilization rates. The company, a leading provider of oilfield services in China, benefited from sustained global energy investment and increased activity in the South China Sea.
Revenue for the quarter reached RMB 12.4 billion, up 8% from the same period last year, according to the company’s earnings call presentation released on Tuesday, August 25, 2026. The results underscore the resilience of the offshore services sector even as oil prices have moderated from their 2025 peaks.
Utilization Rates Hit 85% as Rig Fleet Stays Busy
COSL’s jack-up rig utilization averaged 85% during the quarter, up from 78% a year earlier, reflecting tighter supply in the Asian offshore market. The company operates 37 jack-up rigs and 15 semi-submersibles, with several units contracted through 2027.
“The offshore market is in a sweet spot,” said an analyst who follows the company, noting that day rates for premium jack-ups have risen 10-15% since early 2026. COSL’s management highlighted that its newer rigs, including the HYSY981 deepwater platform, are operating at near-full capacity, contributing to margin expansion.
Cost Controls and Efficiency Gains Boost Operating Margin
Operating margin improved to 19.2% in Q2 2026, up from 17.8% in the year-ago quarter, as COSL maintained strict cost discipline despite inflationary pressures on labor and materials. The company’s focus on digital drilling technologies and supply chain optimization helped reduce per-day operating costs by 3%.
Net income was also supported by a favorable product mix, with higher-margin deepwater services growing 15% year-over-year. Management expects full-year 2026 capital expenditure to remain around RMB 3.5 billion, primarily directed toward upgrading existing rigs and expanding digital capabilities.
China’s Energy Security Push Adds Long-Term Tailwind
COSL’s performance is closely tied to China’s national strategy of boosting domestic oil and gas production to reduce import dependence. According to the National Energy Administration, China’s offshore crude output rose 4% in the first half of 2026, and the government has set a target of 20% offshore production growth by 2030.
This policy backdrop underpins strong order visibility for COSL, with its parent company CNOOC (CEO) committing to record upstream spending in 2026. “We are seeing unprecedented support from national oil companies,” said COSL’s CFO during the call, emphasizing that contract awards have accelerated in the second half of the year.
What to Watch: Day Rates and 2027 Backlog
Investors should monitor COSL’s rig day rates in the coming months, as a sustained rise above $120,000 per day for premium jack-ups would signal continued tightness. The company is expected to release its Q3 2026 results in late October, and any upward revision to its 2027 revenue guidance would confirm the durability of the current upcycle.
Key risks include a sharp drop in global oil prices, which could prompt operators to slow drilling plans, and potential supply additions from competitors in Southeast Asia. For now, COSL’s strong balance sheet and backlog suggest the momentum is likely to persist.
