Basic Understanding about 3D Seismic for Petroleum Exploration

3D seismic is one of the most important techniques to help geologists and engineers to find out where possible hydrocarbon is below thousands of feet below the earth surface. Without 3D seismic technology, many oilfields cannot be discovered.

We’ve found this excellent which will give you some ideas of how 3D seismic works in order to help us find oil and gas. Additionally, we also provide the full video transcript to help someone to learn about this topic. We wish you would enjoy watching and learning from this VDO.

Kill The Blow Out Well Using Nuclear Bomb

We’ve found this vidoe on Youtube and this is one of the most interesting stories of well control. This is about how to kill the blow out well using a nuclear bomb. We are not sure when it was happened but from what you can see, this was quite long time ago when directional technology was not good enough to successfully drill a relief well. Please see the video below and we already added the footage transcript for further learning.

The Luckiest Derrick Man – TDS Drop

You must watch this VDO. In this vdo, it shows that a bad situation can be occurred any time.

It took less than half a minute for this catastrophic happened. The derrick man was extremely lucky because he was in derrick instead of monkey board. This is a right working practicing while working in derrick. We are not sure about the details of this incident but we would like to use this event to raise oilfield safety awareness and learn from other safety incidents to make our work place safe.

What Can We Learn from This Situation?

  • Always be in a safe zone while working in derrick especially when TDS moving.
  • Possible lack of drilling line maintenance or poor quality drilling line
  • Drill floor is one of the most dangerous places on the rig. As you can see from this case, there will be big damage on equipment but we are not sure about people life. We hope they will not get hurt or lost their life.
  • If you don’t have any jobs on the drill floor, you are recommended to stay away from that area.
  • One example of how bad of dropped TDS is Rig 325 Mexico Catastrophic

  • Dynamic dropped object is very dangerous. People spend a lot of time on static dropped objects because they are all visible and easy to recognize. However, dynamic dropped objects are happened when there is movement like this case. Therefore, proper maintenance is the key of success to mitigate this issue.

Travelling Block Falling Down

Anything can happen in just a second while you working. This 1-minute VDO shows you what a catastrophe occurs in just a second.

From the vdo, it seems like the break did not work properly so everything hanging in the travelling block was falling down and hit the drillstring on the rig floor. It did not take long just about 12 second for this case to happen.

This is another event when the TDS and travelling blow falling down to the rig floor.
