Category Description

Drilling Rigs are one of the most important pieces of oilfield equipment and are used during a number of stages throughout the life cycle of oil and gas fields. Land drilling rigs can be of different sizes, power capabilities and used in different applications. 

 

Each rig type serves a different purpose and is best suited to a particular drilling environment. Key differentiation factors in drilling rigs are: 

  • Lifting capacity
  • Horsepower
  • Number of mud pumps and its power and ability to circulate drilling fluid
  • Size 
  • While mobile rigs have limited use, light conventional rigs are the most widely used. However, with shale drilling, multilateral, directional wells, HP/HT and sour wells, the use of hi-tech and high horsepower rigs has been gaining momentum and the demand for these heavy rigs have been increasing. In addition, ambient temperatures (e.g. deserts) can place more pressure on land drilling rig efficiency.  

Below is a summary of how land rigs are used throughout the life cycle of oil and gas fields.

  • During the exploration stage. Rigs are used to drill exploration wells and wildcat wells in locations with the potential for hydrocarbon-bearing geological structures, after being identified from analysing the results from various geological studies and the seismic survey. Most of the time, vertical wells are drilled to ensure safety and well stability and to acquire quality and sufficient subsurface data/knowledge.
  • During the appraisal stage. Rigs are used to drill several wells to understand flow rates, the reservoir dynamics and the size and limits of the reservoir in order to confirm the assumption that hydrocarbons can be economically produced.
  • During the development stage. Rigs are used to drill wells (at a much higher level of activity) to the depth of a productive zone of the reservoir. Wells in this point could be vertical, horizontal or deviated, and could be drilled on a grid or on a pad.
  • During the production stage. Rigs are used to drill more wells, also known as infield drilling or repair/work over existing wells. Depending on the complexity, a smaller work-over rig may be used for a work-over programme and well repair or production enhancements or for other well treatments.  

There is a fundamental shift in the types of land rigs being used today and more advanced and powerful rigs are replacing the old fleet. More challenges are now put onto the rigs, such as drilling multiple wells from a single location, in order to avoid rig moves.  Higher drilling speed and longer laterals drilled are also the norms when wells are drilled from a single location. Standard rigs are usually not equipped to provide the capabilities to meet these challenges as they were designed to drill-move-drill one well at a time. Hence, the industry is experiencing a significant and fundamental change in the land rig fleet.

Generally, the cost of rig services is less than 10% of the overall well cost. However, the performance of the drill rigs is vital to the drilling of a successful well.  

Supply & Demand Dynamics Image

Supply & Demand Dynamics

Demand 

Demand for Land / Onshore Drilling Rigs is directly influenced by the demand growth for fossil fuels and global onshore exploration and production activities; while well intervention and work-over activities have less effect on the demand for drilling rigs, due to there being other well intervention methods and technologies available. However, more wells do not necessarily mean more rigs. Newer rigs are more efficient and with pad drilling, fewer rigs are required to deliver the same or higher number of wells.

Oil price volatility hugely affects the demand for land / onshore rigs, as fewer wells are drilled during the industry downturn. Historically, apart from Russia and the CIS, North America has held the largest share of demand, followed by the Middle East and Latin America.  In the Middle East, Oman, Saudi Arabia and Kuwait are the biggest areas for land rigs. The onshore rig segment in the Middle East has exhibited one of the highest growth rates in the world over the last 20 years.  

The demand patterns between the regions globally  are slightly different, whereby most of the growth in North America is for hi-spec rigs (1,500/2,000 / 3,000 hp) used in horizontal drilling. Historically the Middle East and Russia have used lower specs rigs, with more demand for 2,000 hp rigs (and above) starting to build up 2014 onwards. 

 

Supply 

Outside of Russia and the CIS, North America has been historically the largest market for land rigs of any type, followed by the Middle East. Regionally, around 75 % of the units are drilling rigs, with the rest being work-over units.

The rig fleet has been growing significantly over the last several years, reaching close to 370, with major purchases in UAE, KSA, and Oman.

 

Onshore rigs have different power supply mechanisms, i.e. SCR or AC. SCR is old technology, whereas AC-powered (with variable speed) rigs allows adjusting the load and torque as required. This not only provides drilling efficiency and control but consumes less fuel and reduces wear and tear. The majority of new land rigs globally are equipped with the AC power system. However, in the Middle East, the majority or land rigs are equipped with the SCR system. In the USA, around 70% of the land rigs are AC powered. It is expected that AC powered and rigs will dominate the increase in rig supply capacity around the world.  

 

Suppliers and contractors of land / onshore rigs are divided into rig manufacturers and the suppliers of land drilling services, including the rig crew and other drilling equipment. The latter tend to be provided by regional/local companies, with very little global or diversified service providers.

The Middle East market comprises national/domestic rig contractors and suppliers, as well as international players, with the domestic companies prevailing and controlling more than 70% of the rig fleet (including work-over rigs). Below is an approximate distribution of rig contractors and owners in the GCC region.  Around 40% of the rig count in the region is high spec 2,000hp to 3,000hp rigs, with circa 25% of the units being 1,500hp to 2,000hp rigs and c. 15%  1,000hp to 1,500hp rigs.  Saudi Arabia has the largest number of operating rigs, almost equally followed by Kuwait, Iraq, UAE, and Oman.

Cost & Price Analysis Image

Cost & Price Analysis

Price Analysis 

Operating rates for land rigs have always been driven by supply and demand and been highly sensitive to the oil price and rig utilization.  Land rig operating rates vary between $5k/day to $50k/day, largely depending on the region and rig type. The North American market is the most important indicator of land rig rates.

Indicative day rates for land rigs are as follows ( as of Q3 2020) 

 

North America land rig rates

  • 2,000hp (and above) - $22k-$27k per day
  • 1,500hp - $14k-$17k per day
  • 1,000hp - $8k-$13k per day
  • <1,000hp - < $10k per day

Other regions land rigs indicative rates 

  • 2,000hp (and above) - $35k-$45k per day 
  • 1,500hp - $25k-$35k per day
  • 1,000hp - $15k-$25k per day 
  • <1,000hp - < $10k-$15k per day 

Cost Analysis 

The most notable cost that contributes to the price of the operating rate initial Purchase Cost / Price. The initial purchase cost of a land rig represents a large capital investment for any company. As a guide the following prices can be expected:

  • Rebuilt 1,500hp AC powered -$ 4-8MM 
  • Brand new 1,500hp and SCR powered around $ 10-13 MM
  • Brand new 2,000hp and SCR powered - around $12-16 MM
  • Brand new 3,000hp and AC powered  around $ 18-22 MM

 

Operating costs - Below are major cost elements to operate an onshore drilling rig. 

  • Interest charges ( financing). Depending on the funding of the Initial Purchase (i.e. Debt to equity split) and the interest rates available in the financial market, interest charges can represent a significant contribution to the day rate. 
  • Depreciation. The rig will be depreciated over a period of time, typically 15-30 years. The depreciation cost will contribute to the day rate.
  • Personnel and Equipment. Land rigs operate with as many as 50 crew. As such personnel represent a significant portion of the rig cost. Personnel costs are inclusive of the salaries as well as all other incidentals such as accommodation, mobilizations, and training etc.  Depending on the supply and demand characteristics in the market personnel and equipment rates can vary as crew and equipment are limited in availability.
  • Inspection and Maintenance. Land rigs require regular maintenance to sustain the operation of the various pieces of equipment on board. This may include specialist technical support as well as spare parts and consumables to required. In addition, depending on the inspection requirements that are highly regulated by various industry bodies. This cost (including the lost hire) will be amortized over the inspection period and added into the day rate of the rig.

Total Cost of Ownership Image

Total Cost of Ownership

Although a turnkey drilling contract is fairly common, the majority of drilling contracts today are based on daily work and contain the following units (may not have all of them):

  • Mob /demob fees - lump sum fee to mobilize a drilling rig, fully capable to drill required type of wells, with all required modifications carried out. 
  • Daily operating rate - a hire rate per day to operate a fully manned drilling rig
  • Standby rate - a hire rate per day to operate a fully manned drilling rig and ready to operate, but waiting on instructions from the client. 
  • Reduced performance rate - a hire rate per day, when a drilling rig is not capable to drill as per original criteria, but still able to operate, e.g. slower drilling speed as a result of a broken pump or lack of sufficient mud tanks. 
  • Repair rate - a hire rate per day, when a drilling rig is undergoing repairs. Generally, a cap is imposed and it could be cumulative up to 48 hrs per month. 
  • Remedial ( re-drill) operation rate - a hire rate per day, that is used when a well was lost a result of a malfunction of the drilling rig and a new well is drilled to the same depth/condition as the lost well. 
  • Standby unmanned rate - a hire rate per day to keep the rig stacked and fully maintained, without the crew 
  • Moving rate - a hire rate per day to operate a drilling rig fully manned and ready to operate, but moving from one location to another.  
  • Force major rate - a hire rate per day during a force major event

While this commercial structure has been effective most of the time, it encourages wasteful behaviour. A compensation mechanism that supports better performance is needed. It could be achieved via bonus structures, or, most recent, footage rates, i.e. paying per foot drilled.  Below a comparison of pricing models in the market and its characteristics:


Points to consider for procurement of land rigs:

  • How fast it can be moved in the desert
  • Handling of hot temperatures
  • Design that allows for fast rig-up/down
  • Transit times between drill sites
  • Ability to drill conventional, horizontal and shale wells
  • A drilling rig that is fit-for-purpose
