Directional Drilling Calculation Example for J-Profile Well

This article demonstrates how to design the well trajectory in J-shape from the surface location to the required target depth (TD).

Information Given

  • The surface location coordinate of Well-A is 6,543,065.00N 416,695.00E and the target is located at 6,542,213.00N 415,456.00E and the UTM zone is 31N.

  • Kick off depth = 4,200’MD/4,200’TVD
  • Planned build up rate = 2 degree/100 ft
  • Well profile = J-profile (build and hold)

The surface location coordinate of Well-A is 6,543,065.00N 416,695.00E and the target is located at 6,542,213.00N 415,456.00E and the UTM zone is 31N. Therefore, the surface and the target for Well-A can be illustrated is Figure 1. Continue reading

Drilling an oil well from surface drilling to completion – video training

This is one of excellent training video demonstrating the drilling process from start at surface casing to completing of the well in less than 7 minutes. This would be a good tool to teach people about drilling in our oil and gas industry. We also provide video transcription in order to help learners understand the content easily. If you love this content, please feel free to share with your friends.

Deepwater Sea Life

When you work in deepwater environment (3000 ft + below sea level), you may think what kinds of creatures live in that condition.  Roman Fedorstov  has shared some amazing photos of animal living at that condition. You can take a look that these are animal passing by subsea BOP, riser, etc.

Transocean to sell all jack-up fleet to Norwegian offshore drilling contractor, Borr Drilling

In our opinion, it is very interesting decision made by Transcoean to sell all jack-up fleets to Norwegian offshore drilling contractor, Borr Drilling. With current oil market situation, Transocan has made decision to stay only deep water drilling.

Please feel free to share your thought about this. 

News by Offshore Energy Today 

Norwegian offshore drilling contractor Borr Drilling, formerly known as Magni Drilling, is planning to buy 15 jack-up drilling rigs from Swiss-based Transocean for $1.35 billion.

Borr Drilling announced on Monday the signing of a letter of intent with Transocean for the acquisition of 15 high-specification jack-up rigs.

The transaction consists of Transocean’s entire jack-up fleet, including ten rigs already in the fleet and five newbuilds under construction at Keppel FELS Limited, which Transocean has been postponing for a while now. The latest agreement with Keppel entailed the deferral of the five new jack-ups until 2020. Continue reading
