Kelly or Top Drive is the drilling equipment which transfer both rotational and compression force to the bit in order to make a hole. This vdo training demonstrates the basic understanding for kelly and top drive. Additionally, we add full transcript of this vdo in order to help people learn about this topic effectively. We wish you would enjoy watching and learning from this vdo.

Full Transcript of this multimedia training.

Many pieces of equipment make up our Rotary drilling rig. Part of it’s on the surface and part of its underground or subsurface. All the equipment has one main purpose, to put a bit at the bottom of the hole where it can drill or make holes.

To put the big on the bottom, rig crewmembers screw it into a special pipe. The pipe is called the Drill String. Crewmembers lower the drill string and attached bit into the hole. For the bit to drill, surface rig equipment has to rotate it unless it’s rotated by a mud motor. Equipment also has to put weight on it to force the bit’s teeth cutters into the formation. As the bit rotates, a circulating fluid has to take the drill cuttings away from the bit. Otherwise the hole would clog up. This fluid which circulates is called drilling mud.

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.

Today, we would like to share a valuable VDO training regarding the basic of sub sea BOP. Additionally, we provides learner full VDO transcript to accelerate your learning curve.

Basic Understanding of Sub Sea BOP VDO Transcript

Subsea BOP equipment is similar to a surface stack. There are however some very important differences. This section discusses these differences.

Subsea stacks attached to the well head on the seafloor meanwhile the rig floats on the water hundreds of thousands of feet or meters above. Major parts include;

Nowadays deep water drilling is one of vital players for oil and gas exploration and production industry and there are many people who would like to know how deep water drilling works. We’ve found one excellent VDO demonstrates the deep water drilling process in a simple way. This VDO will give you clearer picture about the topic and we also add full VDO transcript in order to help more people understand the content clearly. We wish you would enjoy learning from this VDO and please feel free to give us feedback : )

How does the deep sea drilling vessel Chikyu drill into the sea floor? When the vessel arrives at the drilling site it receives a satellite signal that helps the vessel moves into the exact position required. The vessel has six propellers that rotate a full 360 degrees and keep the vessel in one position preventing it from drifting due to the wind, waves or sea current.

The blowout preventer, BOP stack, consists of several large valves stacked on top of each other. These large valves are called blowout preventers. Manufacturers rate BOP stacks to work against pressures as low as 2m000 pounds per square inch or psi and as high as 15,000 psi. That is about 14,000 kPa to over 100,000 kPa.

Rigs usually have two kinds of preventers, on top is an annular preventer it is called an annular preventer because it surrounds the top of the well bore in the shape of a ring or an annulus. Below the annular preventer are ram preventers. The shutoff valves in RAM preventers close my forcing or ramming themselves together.

The choke line is a line through which well fluids flow through the choke manifold when the preventers are closed. Even though the preventers shut in the well the core members must have a way to remove or circulate the kick in the mud out of the well. When the BOP shut in the well, mud and formation fluids exit through the choke line to the choke manifold. The manifold is made up of special piping and valves. The most important valve is the choke.
