... Abstract In the Gulf of Thailand (GOT), deep directional drilling wells are planned with two runs using motor and adjustable-gage-stabilizer (AGS) bottom hole assembly (BHA) in the 6-1/8-in. hole section or the rotary-steerable-system (RSS) BHA. However, the cost of the RSS is not economical...

... Abstract Published numerical and analytical solutions for wellbore stability predict certain trends in the behavior of hole geometry as a function of time. In general, shear failure is expected to increase in severity with time to produce over-gauged hole sections. However, these solutions do...

... damange to cutters, especially PDC cutters. These challenging zones were encountered in 12.25-in or 8.5-in hole sections, where multiple bit runs were normally required to drill to the section total depth (TD) due to a low penetration rate as a result of worn or broken bit cutters. This situation reduced...

Therefore, narrow margin procedures and processes were implemented in each hole section after the BOP had been landed, until well TD had been reached. The pre-drill plan...

Shallow reservoirs need to be evaluated for hydrocarbon potential, but these shallow hole sections are in very large hole sizes that require optimizing the drilling and formation evaluation.
