Well Control Barriers.

 


One of the worst accidents that could happen to a rig is a blowout.
A blowout is a situation when there is uncontrolled flow of fluid from the well.
Before a blowout, there is always a kick which is an influx of formation fluid into the wellbore. If left unchecked, could eventually lead to a blowout.
There are two most important well control barriers:
1)Primary Well Control-Hydrostatic Column of the drilling fluid.
2)Secondary Well Control-BOP (Blowout Preventer)
A blowout can only occur when the rig has lost all controls of secondary well control.
Which is why the well control awareness is important to every person onboard.
There are two main organizations providing well control certificate namely
-IADC (International Association of Drilling Contractors)
-IWCF (International Well Control Forum)

Difference between Semi Tender and Tender Assisted Rigs

Image
  This time we will be talking about tender and semi tender rigs. They are one of the most commonly used rig types in offshore, especially in offshore. Semi tender and tender rigs are usually stationed beside the platform. For example (West Vencedor from Seadrill in Yetagun Campaign, Myanmar) So what are the advantages of semi/tender rigs? 1) Self-raise capability. Can remove its own drilling package and then rig-up on the same package on another platform. 2)Large deck space to store the drilling equipment. 3)Could be fabricated in many yards. 4)Can be utilized as a construction barge depending on the conditions. 5)Can be used where the platform is out of reach from jackup's cantilevers. So what are the disadvantages: 1)Cannot operate in deep water conditions. 2)Cannot withstand rough weather conditions. 3)Weight sensitive. The difference between semi tender and tender rig is the hull design. Since semi tender is a semi submersible, it can operate in deeper water, can withstand to ...

Should we convert to Renewable Energy?

  Should we convert to Renewable Energy? မြန်မာ version below Over the past years, there has been a lot of efforts to convert our main energy source to renewable energy, instead of fossil fuel and nuclear. A lot of solar farms and huge wind farms have been appearing around the world. Major Oil & Gas companies has been pushing their image towards that as well. So, lets us discuss some of the drawbacks about Renewable Energy. -Getting the free energy from wind and sun is a great idea. Except for the fact that those are very dilute energy sources since they are "Natural". Have you ever come across a photo of solar farm while browsing? -They are huge, like a lot. What most of the people are not seeing is the amount of trees and wildlife needs to be clear from that area is enormous. -If you compare the energy output of a nuclear reactor to a solar farm (Ivanpah, California), you need 450 times 3500 acres to cope up with the energy output of the nuclear reactor. Do you know Ger...
