Introduction to Drilling Reamers

In the world of drilling, precision and efficiency are non-negotiable. Reamers, specialized tools designed for wellbore enlargement and optimization in the oil and gas industry, are essential in achieving these goals. This comprehensive guide explores the functions, applications, and mechanisms behind drilling reamers.

What are Drilling Reamers?

Drilling reamers, often referred to simply as reamers, are crucial components in drilling operations. These tools are specifically engineered to enlarge and optimize the borehole, ensuring a smooth and uniform wellbore profile. Drilling reamers come in various designs, each tailored to meet specific drilling challenges and objectives.

Applications of Reamers

Borehole Enlargement

The primary purpose of drilling reamers is borehole enlargement. As drilling progresses, the wellbore diameter may need adjustment to accommodate casing strings, improve fluid circulation, or optimize wellbore geometry. Reamers excel in achieving these objectives, ensuring a wellbore of the desired size and shape.

Stabilization and anti-deviation

Reamers can serve as stabilizing tools, helping maintain the borehole’s trajectory in directional drilling projects. By reducing the risk of hole deviation and minimizing lateral vibrations, they contribute to drilling accuracy and minimize costly complications.

Enhanced Hole Cleaning

Efficient hole cleaning is vital for successful oil and gas drilling operations. This is because reamers play a pivotal role in improving hole cleaning by creating a smoother wellbore surface. Having a smoother wellbore surfaces reduces the likelihood of cuttings settling at the bottom of the hole, and it enhances drilling fluid circulation.

How do Drilling Reamers work?

Design and construction

Drilling reamers are cylindrical tools designed to fit within the drill string. They feature cutting structures such as blades, cutters, or PDC (polycrystalline diamond compact) elements. These structures are strategically positioned to remove excess formation material as the reamer rotates.

Enlargement Mechanism

The operation of drilling reamers relies on an active enlargement mechanism. As the reamer rotates, the cutting structures engage with the borehole wall, shaving away excess material. This process continues until the desired borehole diameter is achieved. The removed material is carried to the surface by the drilling fluid.

Selecting the Right Reamer

Choosing the appropriate drilling reamer is essential for a successful drilling operation. Factors such as formation type, wellbore size requirements, and drilling parameters must be considered. Consulting with drilling experts and conducting thorough engineering analyses can aid in selecting the ideal reamer for a specific project.

Innovations in Drilling Reamers Technology

Self-adjusting Reamers

Recent advancements in drilling technology have given rise to self-adjusting reamers. These tools feature mechanisms that automatically adapt to changing wellbore conditions. By continuously optimizing the borehole size and shape, self-adjusting reamers enhance drilling efficiency and reduce the risk of getting stuck in the hole.

PDC Reamers

The use of PDC (polycrystalline diamond compact) technology in reamers has revolutionized drilling. PDC reamers feature diamond-tipped cutters that offer exceptional durability and cutting efficiency. These reamers excel in challenging formations, providing longer service life and improved performance.

Real-time monitoring

The integration of sensors and real-time monitoring systems into drilling reamers allows operators to gather data on downhole conditions. This data can be used to make informed decisions about reamer adjustments, optimizing drilling efficiency and reducing operational risks.

Reamers FAQ

Please note that beside the ranges below, we also offer custom tool sizes for odd hole sizes upon request.

Fixedblade Reamer

  • 12 1/4″ series
  • 8 1/2″ series
  • 6″ series


Switchblade Range

  • 17″ Series
  • 16″ Series
  • 12″ Series

Please note
The Switchblade can be configured as a Stabilizer or a Reamer, or a combination of both, (the hybrid version). The drilling stabilizer version is adjusted by 1” (inch) in increments of 1/8”. The Reamer version is Adjustable by ½” (inch) in increments of 1/8”. The blades are all interchangeable throughout the range from the 12” series through to the 17” series.

We offer a range of different types of hardfacing tungsten carbide tiles HF3000 (Quicktip), HF5000 to HF6500. However, we usually go with what is readily repairable in the region where tools are deployed. We also offer diamond enhanced hardfacing upon request.

The difference between our hybrid reamer and fixed cutter reaming tools is that the operator can configure the tool to suit a variety of applications. For instance: the tool can be configured to have an inactive cutting action when drilling and a reaming capability if required when POOH. The depth of the cut of the reamer blades can be determined by adjusting the height of the stabilizer blade if required, the tool can be configured as a full-reamer, or a stabilizer, or a combination of both reamer and stabilizer i.e. hybrid reamer.

Due to the ability to alter the outer diameter of both reamer and stabilizer blade the tool can be configured to cover a range of applications. The stabilizer blade can be adjusted to limit the depth of cut of the reamer cutters, to reduce rotary torque and vibration. The reamer blades can be gauged to have a passive cutting action when drilling and a reaming capability when pulling out of highly deviated wells when required.
