Blow Out Preventer (BOP) Equipment VDO Training

BOP equipment is one the most critical equipment for well control operation. Learning about it via VDO training is a good way to understand this subject because you can see what the equipment look like, how these equipment relates to the operation. This VDO will teach you several topics about the BOP equipment as BOP stack, choke manifold, choke panel, accumulator, etc. Additionally, the full VDO transcript is provided to aid your learning.

Blow Out on The Rig Floor VDO

This short VDO will show you how fast of the kick blowing out to the surface. It is worth for your time to watch and learn from this 57-second vdo.

We don’t know detail about it why this was happened but we can learn from this incident.

  • Always monitoring the well while drilling
  • Be proactive of well control indicators
  • Frequent well control drills are recommended to perform.
  • Emergency abandon rig drills must be practiced often.
  • Escape route plan while being on the rig floor
  • Try to be away from the rig floor if you don’t have any tasks involving in drilling operation at that time
  • Always prepare for unexpected situations.

Blow Through Situation in Mud Gas Separator (Well Control Equipment)

Mud leg provides hydrostatic pressure in order to prevent mud going through the separator into the rig. If the pressure in the mud gas separator exceeds hydrostatic pressure provided by mud leg, gas blowing through situation will be happened. Once blow-through occurs with a mud gas separator, it is very difficult to stop this situation until the mud leg column is re-established.

Figure 1 illustrates mud-blow through. The pressure that will create blow-through can be calculated by determining hydrostatic pressure of mud leg. Continue reading

Determine Correct Initial Circulating Pressure (ICP)

Correct initial circulating pressure is very important for well control operation because the correct ICP figure will tell you about the balance point while circulating the influx out using Driller’s method. Many people get confused when they try to get the right ICP because they tend to forget about a safety factor that is added while bring the pump to speed. Hence, the ICP with unintentionally added safety margin may fracture formations downhole because people will tend to add more safety factor while circulating. It means that excessive safety factor added into the system will make the well control operation worse.
