Drilling Services: Rig Economics and Dayrates

Introduction

Drilling services represent the foundational OFS segment: without drilling rigs, no new wells can be drilled and no new production can be brought online. The drilling contractor business model is conceptually simple (rent a rig and crew to an E&P company at a daily rate), but the economics are heavily cyclical, capital-intensive, and shaped by the supply-demand dynamics of a specialized equipment market that responds to upstream capital spending decisions with a significant lag.

For energy bankers, understanding rig economics and dayrate dynamics is important for OFS company valuation, for forecasting E&P drilling costs (which are a key input in NAV models), and for evaluating OFS M&A transactions.

US onshore drilling is dominated by horizontal rigs capable of drilling directional wellbores into shale formations. These rigs are sophisticated pieces of equipment costing $15-30 million each to build (for a modern, high-specification AC electric rig), with a productive life of 20-30 years and significant ongoing maintenance requirements.

Dayrate (Onshore)

The daily fee charged by an onshore drilling contractor for the use of its rig, drill string, and operating crew. The dayrate covers the cost of the rig equipment, crew labor, rig maintenance, and the contractor's profit margin. The E&P operator separately pays for fuel, drilling fluids, directional drilling services, cementing, and other third-party services. US onshore horizontal rig dayrates typically range from $25,000-35,000 per day depending on rig specification, with the newest, most automated "super-spec" rigs commanding premium pricing at the top of the range.

Onshore rig contracts in the US are typically short-term (well-to-well or 6-12 month terms), which means dayrates can adjust relatively quickly to market conditions. When the rig count is rising and rigs are fully utilized, contractors can increase dayrates. When the rig count falls, excess rigs become available and dayrates decline. The speed of this price adjustment makes onshore rig dayrates a sensitive indicator of the upstream activity cycle. However, onshore rig contractor margins are structurally thin (EBITDA margins of 15-25% even in favorable markets) because of the large number of competing contractors and the relative ease of deploying alternative rigs. This competitive intensity differs from the offshore market, where the limited number of deepwater-capable rigs and long lead times for new construction create more favorable pricing dynamics during upcycles.

The onshore rig market has also consolidated significantly. Major onshore contractors include Helmerich & Payne (the largest US onshore rig operator by fleet size), Patterson-UTI Energy (which merged with NexTier Oilfield Solutions in 2023 to create a combined drilling and completions platform), and Nabors Industries. The consolidation trend has reduced the total number of competitors and improved pricing discipline, though the market remains more fragmented than the offshore segment.

Rig count trends. The US land rig count peaked at approximately 750 in late 2022 during the post-COVID recovery, declined to approximately 580 by mid-2025, and has stabilized in the 550-600 range. The decline reflects the capital discipline paradigm: E&P companies are spending less on drilling (reinvestment rates of 40-60%) and using fewer but more efficient rigs that drill more wells per year through improved drilling speeds and multi-well pad operations.

Offshore drilling economics differ fundamentally from onshore in scale, contract duration, and dayrate magnitude.

Rig types. Three categories of mobile offshore drilling units (MODUs) serve different water depth ranges. Jackup rigs (self-elevating platforms that stand on the seabed) operate in shallow water (up to approximately 400 feet) and command dayrates of $100,000-180,000 per day. Semisubmersible rigs (floating platforms anchored by mooring systems) operate in intermediate to deep water (500-8,000+ feet) and command $250,000-400,000 per day. Drillships (ship-shaped floating rigs with dynamic positioning) operate in the deepest water (up to 12,000 feet) and command $350,000-500,000+ per day.

Contract terms. Unlike short-term onshore rig contracts, offshore rig contracts are typically multi-year (1-5 years), providing revenue visibility but also creating fixed-price risk if market dayrates move after the contract is signed. E&P operators lock in rig capacity well in advance of their drilling programs, and the backlog of contracted rigs is a key metric for offshore drilling contractor valuation.

2025 market dynamics. After two years of steady offshore rig market recovery (2023-2024), 2025 saw adjustments. Active offshore units dipped to approximately 502 with utilization at 80%. Saudi Aramco's suspension of over 40 jackup rigs (as part of Saudi Arabia's production discipline under OPEC+) reduced Middle Eastern rig demand, though approximately 40% of suspended units were redeployed to Southeast Asia and the Far East. Average deepwater dayrates eased to the low $400,000s from 2024's higher levels but remain well above the trough of $150,000-200,000 seen in 2020-2021.

The Baker Hughes rig count is the most widely followed leading indicator for OFS activity. Published weekly (Friday for North America, monthly for international), it tracks the number of active drilling rigs by type (oil vs. gas), geography (basin, state, country), and specification.

The rig count is an imperfect indicator because rig efficiency has improved dramatically: a single modern super-spec rig can drill 20-30% more wells per year than a rig from 10 years ago, due to faster drilling speeds, walking systems that allow quick moves between well pads, and automated drilling controls. This means the same rig count can support higher production today than in the past, which is one reason US oil production has continued to grow modestly even as the rig count has declined from its 2022 peak. For energy bankers, this efficiency improvement means that simple rig count trends can be misleading as a proxy for activity: the "wells drilled per rig per year" metric (which has improved approximately 20-30% over the past decade) provides a more accurate picture of actual drilling throughput. When building OFS revenue models, bankers should use wells drilled (not just rig count) as the primary activity driver, adjusting for the ongoing efficiency gains that allow fewer rigs to drill the same number of wells.
