2. Drilling engineering - Wikipedia

   en.wikipedia.org/wiki/Drilling_engineering

   Drilling engineering is a subset of petroleum engineering. [1] Drilling engineers design and implement procedures to drill wells as safely and economically as possible. [1] They work closely with the drilling contractor, service contractors, and compliance personnel, as well as with geologists and other technical specialists.

4. Well drilling - Wikipedia

   en.wikipedia.org/wiki/Well_drilling

   Well drilling is the process of drilling a hole in the ground for the extraction of a natural resource such as ground water, brine, natural gas, or petroleum, for the injection of a fluid from surface to a subsurface reservoir or for subsurface formations evaluation or monitoring.

   Producing boreholes with wide range of diameters or drilling in water environment can be mentioned. The research team from Slovakia has developed drilling concept based on utilization of electrical plasma. The core of the research is held in Research Centre for Deep Drilling which was opened in the premises of Slovak Academy of Sciences.

7. Measurement while drilling - Wikipedia

   en.wikipedia.org/wiki/Measurement_while_drilling

   A drilling rig is used to create a borehole or well (also called a wellbore) in the earth's sub-surface, for example in order to extract natural resources such as gas or oil. During such drilling, data is acquired from the drilling rig sensors for a range of purposes such as: decision-support to monitor and manage the smooth operation of ...

8. Directional drilling - Wikipedia

   en.wikipedia.org/wiki/Directional_drilling

   Directional drilling (or slant drilling) is the practice of drilling non-vertical bores. It can be broken down into four main groups: oilfield directional drilling, utility installation directional drilling, directional boring (horizontal directional drilling - HDD), and surface in seam (SIS), which horizontally intersects a vertical bore ...

9. Drill bit (well) - Wikipedia

   en.wikipedia.org/wiki/Drill_bit_(well)

   Regardless of type, drill bits must satisfy two primary design goals: maximize the rate of penetration (ROP) of the formation and provide a long service life. The reason for this is a direct consequence of the rotary drilling method. Modern oilfield drilling operations require substantial capital and operating expense.
