Drill bits are used in the oil and gas industry as a component which produces holes of almost circular cross-section in the earth’s crust for the extraction of crude oil and natural gas. It is majorly deployed in the rotary drilling method to produce the hole in the fields. There are various types of drill bits of different shapes and sizes. These are used by the industry to remove materials in order to create holes.
The drill bits technology has improved over a period of time and increased in terms of types. The primary types of drill bits available in the market are roller-cone, polycrystalline diamond cutters (PDC), diamond-impregnated drill bit, fixed cutter, and others. The manufacturers have now introduced a special kind of drill bit that can create holes with the non-circular section. With all these changes happening around the corner, the drill bits industry seeks enhanced efficiency and market conditions.
Creating a hole has been a primitive objective of drill bits but its demand has increased because the tool has maximized the rate of penetration of the formation produced through drilling. Drill bits offer benefits like precision in drilling, ease in the drilling process, and enhancement of the service life of the hole. All these reasons have led to a significant improvement in the drill bits market and helped the drill bits manufacturers look for better opportunities in the future.
The oil and gas drill bit market has been segmented on the basis of product, end user, and region. The growth drivers have been common for all the segments of the market. With the rise in shale gas exploration activities on a global scale and development in the demand for customized drilling bits that can handle unconventional rock formation, the market of the various types of drill bits have seen a major rise. The market is set to rise and touch USD 7.62 billion by 2022. It was found that in the year 2014, roller-cone bit captured the largest product segment of the drill bits market and accounted for over 70% of total market volume. It is because this type of drill bit, particularly those manufactured from tungsten carbide inserts are designed to operate in conventional formations and offer an excellent rate of penetration (ROP) in the initial stage of drilling.
In the year 2014, the oil and gas drill bit market demand was 2,835.0 hundred units which is anticipated to grow at a CAGR of 5.1% in the forecast period of 2015 to 2022. One of the most benefited types of drill bits, roller-cone bit had a demand of over 1,090 hundred units in 2014. The gradual increase in demand has made the manufacturers hopeful for the better market outlook in future.
Some of the major drill bits manufacturers in the oil and gas industry are:
Baker Hughes, a GE company is a full-stream provider of oilfield products, services and digital solutions. There are various types of drill bits offered by the company which can stay in the hole for a longer duration with fewer trips at lower cost-per-foot. The company uses engineering software tools to evaluate an individual’s challenges, identify the root cause, and design custom solutions. The different types of drill bits offered by the company are:
Varel Oil and Gas Drill Bits is one of the leading manufacturers of drill bits. The company is constantly working towards improving the design of the bits in order to overcome the precision problem and enhance the life of the service life of the hole. The various types of drill bits provided by Varel are mentioned below:
Schlumberger has been serving the industry from the past 80 years. It is one of the major manufacturers of drill bits and uses the latest technologies to fit in all the needs of the customers. The different types of drill bits manufactured by the company are:
The drill bits companies are manufacturing different types of drill bits and developing numerous technologies to enhance consumer experience and cut well drilling cost. These technological advancements have led to more efficient drilling experiences. With the introduction of PDC in the 1970s, drilling mechanics changed drastically and became more about strength, durability and resistivity. Similarly, many recent innovations in the drill bits technology have given a new dimension to the drilling industry.
The present-day engineering expertise that we witness in the drill bits industry is an outcome of years of consistent efforts in materials and designs aimed at greater efficiency in drilling operations and extending bit life by enhancing the rate of penetration, improving wear resistance. Landmark changes occurred in the design and functioning of the drill bit when the industry was given polycrystalline diamond compact (PDC) bit.
It is different from the conventional roller cone bit as it has a specialized cutting structure. Its cutter has two parts: a polycrystalline diamond table and its substrate. It is improving the ROP in many difficult wells on a global scale. The bits have ONYX 360 rolling cutter which has incomparable performance in abrasive lateral applications. Statistics have shown that the PDC drill bits offer 56% more footage drilled compared with that of the fixed cutter drill bits.
Some of these features have made PDC more efficient than the other types of drill bits. The ongoing advancements in the drill bit industry are improving the performance of the drilling industry and changing the overall mechanics of drilling.
Cruzer™ Depth-of-Cut Rolling Element by Halliburton
Halliburton introduced the Cruzer™ depth-of-cut rolling element as an improved and enhanced version of its PDC fixed cutter drill bits. This is now one of the most popular types of drill bits manufactured by the company. This exclusive PDC technology takes on the most challenging formations and has many important features like abrasion resistance, impact resistance, and thermal mechanical integrity. Some of the benefits of this technology are: lower coefficient of friction for low torque and low heat generation, has diamond and carbide which keep the rolling element in place and minimizes wear, small package size works for existing designs or new designs and its elements are repairable and replaceable for future runs.
Tektonic™ drill bit platform by NOV
NOV’s new improvement supports drilling efficiency by maximizing ROP, durability, steerability, and stability. The bit has fine geometry, improved cutter layout along with the superior hydraulic design methods, and the next generation of PDC mirrored cutter technology. This highly improves the drilling efficiency even in the most challenging drilling environments. Main features of Tektonic are:
What lies ahead for the drill bits industry?
The different types of drill bits have witnessed numerous improvements in terms of design and functioning which has resulted in better performance. This has created a positive market outlook for the drill bits and oil and gas industry on the whole. With the rise in the demand for shale and other unconventional resources, the demand for drill bits is increasing parallelly. This has given the industry a brighter perspective to look at for the future.
