Frequently Asked Questions: Drill Bits


What is a Drill bit?

A drill bit finds application while cutting through a rock at the time of drilling an oil or gas well. This cutting tool is employed for cutting or crushing the rocks. This rotating apparatus is generally composed of two to three cones. In order to drill sharply through a work-piece, the right selection of drill bits is very important.


What are the different types of drill bits?

Some of the various kinds of drill bits are: Steel Tooth Rotary Bits, Insert Bits and Polycrystalline Diamond Compact Bits. In order to tackle specific drilling challenges, the hybrid of these drill bits also exist.


How is a drill bit selected?

Considering the type of formations encountered, drilling engineers select the drill bits. They also have to see if directional drilling is needed, for a particular temperature range, and also if well logging is being done. The important variables that should be taken into the consideration while selecting a drill bit are, hardness of the rock, abrasive rock, whether the rock is competent or fractured, type of drill rig, depth of drilling expected, level of drilling expected, knowledge of the area, bit range and the right waterway configuration. Moreover, it is every important to evaluate results and make adjustments while choosing the best drilling bit.


What are Dual diameter drill bits?

Dual-diameter bits take into account the already identified challenges by employing unique physical principles to provide for an efficient, reliable means of drilling. The shoulder-to-gauge area of bit’s cutting structure faces lower effective rock strength due to the concentric dual-diameter present in this kind of drill bit.


Which is the most popular choice of drilling in the oil and gas industry?

Rotary drilling is most popularly employed in this industry. It uses a rotating drill bit to grind, cut, scrape and crush the rock at the bottom of the well. This drilling method is contrary to Percussion Drilling in which, a heavy weight is continuously dropped in the well bore to chip away the rock.


What are the different types of drilling designs employed?

To achieve different results, various drilling designs are put to application such as, Core bits, Mill bits and Fishtail bits. Core bits is employed to gather formation cores for well logging; mill bits helps to remove cuttings from the well; and fishtail bits, enlarges the drill hole above the drill bit.


Which are the recently developed drill bit designs?

To mention a few, TerrAdapt adaptive drill bit by Baker Hughes, AxeBlade ridged diamond element bit by Schlumberger’s Smith Bits, Cruzer depth-of-cut rolling element by Halliburton, have been developed to enhance efficiency and reduce operational costs.


What are the challenges associated with drill bits?

Challenges in terms of rate of penetration (ROP) and durability accelerate as wells are drilled deeper and into tougher and more abrasive formations. The rig rates globally are on a rise owing to increased drilling activity. Consequently, the drilling engineers have to re-evaluate the processes and their components, in order to bring down the costs.
