... Abstract Historically, running large diameter surface and intermediate casing in the shallow sections of a well with a high build rate and inclination has proven to be very challenging, with a high risk of getting stuck off bottom. At the same time, with limited drilling margins, it has become...

... Abstract The first highly deviated Deep Water well with an inclination up to 80° was drilled in Mexico. A strategy developed in collaboration with the owner and Directional Drilling contractor allowed to safely drill the well within AFE and reach all planned objectives. In order to maximize...

The modelling further identified a relatively large sensitivity towards borehole inclination – even at fairly small inclinations. This paper thus illustrates...
