What Is the Day Rate (Oil Drilling)?

4 Min.

The day rate for drilling an oil well includes the cost of running the rig, supplying equipment, and paying employees. These costs typically make up half of the total cost of drilling an oil well. Additionally, the day rate tends to increase with higher oil prices and rig utilization rates.


The day rate in oil drilling encompasses the comprehensive daily rental expenses for a drilling rig. The drilling contractor, responsible for providing the rig, personnel, and incidentals, receives this payment from the project operator. Typically, a flat contract fee is agreed upon by oil companies and drilling contractors, from which the day rate is derived by dividing the total contract value by its duration in days.

The Formula for Day Rate (Oil Drilling) 

To calculate the day rate for oil drilling, divide the contract's total value by the duration of the contract in days:

Day Rate = Total Contract Value / Number of Days in Contract

Decoding Insights From Day Rate

Day rate (oil drilling) serves as a vital indicator for investors analyzing the oil and gas industry's overall well-being. Constituting approximately half of an oil well's cost, the day rate assumes significant importance. Despite this, the paramount metric remains the price of oil within the oil and gas sector. Investors keen on understanding the dynamics of oil supply and demand closely observe indicators like day rate and rig utilization, complemented by a global inventory assessment. The volatility in day rates, offering a window of fluctuation, aids investors in gauging the drilling market's vitality. For instance, a decline in day rates may prompt investors to consider divesting their oil and gas positions.

Utilizing Day Rate: An Illustrative Case

Day rates serve as a valuable tool for gauging current oil demand, providing a glimpse into prospective oil price trends. A surge in oil prices amplifies the number of viable projects, including challenging formations and unconventional reserves. This, in turn, heightens competition for oil rigs, elevating day rates. Conversely, fluctuating and decreasing oil prices cause a dip in the day rates for rig rentals.

In a tangible example, Transocean secured a contract with Chevron in December 2018 for drilling services, covering a five-year span and valued at $830 million. For the single rig engaged, the effective day rate computes to $455,000: $830 mill. / (5 years x 365 days) = $455,000.

Analyzing Oil Drilling: Decoding Day Rate vs. Utilization Rate

Within the oil and gas sector, both day rate and rig utilization rate play pivotal roles in assessing its overall condition. The day rate delineates a significant portion of drilling costs, whereas the utilization rate quantifies the wells in active operation. Investors closely monitor these indicators, as a decline in either may indicate a deceleration in oil demand. Elevated utilization rates indicate substantial use of a company's fleet, implying an upsurge in oil demand and, subsequently, oil prices. Notably, both day rates and rig utilization demonstrate a positive correlation with oil prices.

Constraints in the Use of Day Rate

The consistency in the correlation between oil prices and day rates varies. It's notably strong when both oil prices and rig utilization are high. In such cases, day rates surge almost in tandem with prices. During a period of escalating oil prices and high utilization, day rates in long-term contracts escalate even faster than in short-term ones, as rig operators seek a premium for project commitment. Contrarily, in a low-price scenario with declining utilization, the day rate might plummet more rapidly than oil prices. Rig operators, aiming to remain active during a potential slowdown, submit low bids on long contracts. Given this volatility and fluctuating correlation strength, investors and traders may interpret day rates alternatively as leading or lagging indicators concerning oil prices and the oil and gas industry's overall health.


The day rate in oil drilling plays a pivotal role in understanding the economics of the oil and gas industry. It encompasses a substantial portion of drilling costs and varies in response to oil prices and rig utilization rates. Investors closely monitor day rates as an essential indicator for assessing the industry's health and dynamics. A surge in day rates often accompanies high oil prices, indicating increased demand for drilling services. Conversely, during periods of declining oil prices and utilization, day rates may dip. The relationship between day rates and oil prices can vary, making it a valuable but sometimes complex metric for interpreting market conditions and investment decisions.
