Polycrystalline Diamond Compact (PDC) Bits
PDC Bits are the workhorses of the oil field. Features such as cutter types, cutter layout, and blade geometry are continuously being evaluated and improved to deliver value and drive down drilling costs. Certification with the IDEAS integrated dynamic design and analysis platform ensures these bits offer optimal performance. Additionally, the IDEAS platform and field […]
Oil Well Drilling
It is a complex operation and the drilling industry engages the services of personnel and a complicated array of machinery and materials to drill an oil/gas well to depths greater than 6000 meters, The drilling industry has seen technological progress, however, these advances have not changed the fact that, besides the use of complicated machinery, […]
Whipstock Drilling
It is a directional drilling technique that is used to change the direction of an existing wellbore. This technique is typically used to sidetrack from an existing wellbore, which means that a new wellbore is drilled from the same wellhead as the existing wellbore. This can be done for a number of reasons, such as […]
Drill String Vibrations: The Problem & The Solution
Drill string vibrations can significantly impact the performance of oil and gas drilling operations. They can lead to premature wear and tear of drilling equipment, resulting in fatigue and induced string failures such as drill pipe washout. Additionally, they decrease the drilling energy delivered to the bit. Therefore, it will cause a drop in the […]
Stuffing Box Leaking
Purpose of a Stuffing Box:A stuffing box is used to maintain or seal the pressure of fluid during unit operation. The pumping unit moves around the rod to pull whatever you are trying to access — such as oil — to the surface. The stuffing box helps maintain the correct pressure inside the unit during […]
Underbalanced Drilling UBD
When drilling a well and keeping the wellbore fluid gradient below that of the natural formation gradient, this is called Underbalanced Drilling (UBD) and it has its differences with traditional methods. Namely, the well can flow throughout the drilling because the bottomhole circulating pressure always remains lower than the formation pressure. As well as penetrating […]

Directional Driller
One of the responsibilities of a directional driller is to correctly grade a bit after it has been used in a drilling operation. Grading bit by IADC classification a used bit is important because it determines whether or not the bit can be re-run or a back up is picked up for the 2nd run. […]
Crude Oil
Crude oil is a mixture of comparatively volatile liquid hydrocarbons (compounds composed mainly of hydrogen and carbon), though it also contains some nitrogen, sulfur, and oxygen. Those elements form a large variety of complex molecular structures, some of which cannot be readily identified. Regardless of variations, however, almost all crude oil ranges from 82 to […]
