Why Was This Well Control Situation Happened?

You need to watch the VDO below. It demonstrated the situation before the blowout was occurred.

These are some possible root causes which contributes to this situation.

why-this-well-control-happen

  • Improper hole fill
  • Lack of properly tracking the trip sheet
  • Incompetent crew
  • Full Openning Safety Valve and IBOP were not properly prepared to stab in. The crew were looking at them when they found out that the flow was coming up from the drillstring.
  • No float valve in the drillstring
  • Take to long to shut the well in. You can see only 4 minutes before the massive blowout was blowing on the rig floor.
  • Lack of well control knowledge and training
  • Possible to swab the well in
  • What do you think about this well control situation?

What is the longest, deepest and largest hole ever drilled on earth?

This is very interesting information about the longest, deepest and largest hole ever drilled on earth. You will be amazed how people can overcome the limit of nature.

Longest Hole

In May 2008, GSF Rig 127 operated by Transocean drilled (BD-04A) in the Al Shaheen Oil Field for Maersk. It has a measured length of 40,320 feet (12.3 km) with a horizontal section of 35,770 feet (10.9 km). Maersk Oil’s well also extended the company’s previously held world record for the longest horizontal well by 9,000 feet (2.7 km). The entire horizontal section of the well is placed within a reservoir target which is only 20 feet (6 m) thick. And it was completed in 36 days. Incident free. Continue reading

Choke Line Friction – How Does It Affect Deepwater Well Control?

Choke line friction (CLF) is the frictional pressure which is generated while circulating mud through choke or kill line. For surface stack, the choke line friction is negligible because the choke line is short therefore the friction pressure is so small. However, the choke line friction in deepwater operation has a big effect bottom hole pressure. Killing the well without considering the CLF will add excessive pressure and it increases the chance of fracturing formation at casing shoe or anywhere in the well.

Oilfield Casing Data Sheet Free Download

Casing information is very important part of working in the oilfield. This information is used in several calculations as expected displacement volume, cement calculation, stuck pipe calculation, burst/collapse, casing design, etc. Therefore our team collects casing data into one spreadsheet and pdf file for you to download.
