Pressure under the earth is one of the most dangerous things that drilling personnel need to deal with. If the pressure does not take care properly, lost of the well can be occurred.  Learning the basic about pressure control is very critical therefore we would like to share this valuable oilfield VDO regarding this topic. Additionally, full VDO transcript is provided for accelerate your learning. We wish you would enjoy watching and learning from it.

Fluids in a formation are under pressure. When drilled, this pressure can escape to the surface if it is not controlled. Normally, drilling mud offsets formation pressure, that is the weight or pressure of the drilling mud keeps fluids in the formation from coming to the surface.

Geologists have known for years that substantial deposits of oil and natural gas are trapped in deep shale formations. These shale reservoirs were created tens of millions of years ago. Around the world today with modern and horizontal drilling techniques and hydraulic fracturing, the trapped oil and natural gas in these shale reservoirs is being safely and efficiently produced, gathered and distributed to customers.

Let’s look at a drilling and completion process of a typical oil and natural gas well. Shale reservoirs are usually one mile or more below the surface.  Well below any underground source of drinking water, which is typically no more than 300-1000 feet below the surface(Figure 1)

There are many components that make up the drill string as shown in this graphic. Drill pipe is a strong but relatively lightweight pipe. Crew members attach it to a top drive or Kelly. Drill pipe forms the upper part of the drill string. Usually the drill pipe rotates which also rotates the bit. Each section of pipe is called a joint. Crew members screw together or make up several joints and put them in to the hole as the bit drills.
