... Abstract It can be difficult to explain wellbore instability events with current state-of-the-art wellbore stability workflows. Many times, one may observe toolmarks on the cavings at surface, indicating contact between wellbore wall and drillstring/BHA. This work integrates three state...

.... As discussed later in this paper, the decay time is also very affected and reduced by an optional stabilizer having a suitable damping action. For all cases, the bending resistance is a base damping mechanism which is poor and inefficient for low frequencies but much more efficient for higher frequencies...

... Abstract Various stabilizer types are used in the industry, such as bladed stabilizers with straight or spiral blades, roller-reamers, and other emergent forms. Their designs are proved, via many in-field measurements, to have a significant impact on vibration levels. Although experimental data...

The tool drilled to the target depth in a single run, thereby achieving all directional...

... Abstract The objective of this paper is to share lessons on stabilizer selection with the industry that minimize drilling and tripping problems. Ideally the stabilizers and BHA will drill a round, ledge free hole, without patterns, with minimum vibration, minimum unplanned dog legs, that reach...

... mechanisms are described in some detail and the transversal line response is studied with and without fastline stabilizers applied to reduce the vibration amplitudes. Two type of models have been used in the study, a simplified linear model suitable for frequency analysis and another more advanced...

... is a short RSS that is designed to deliver a 15 degrees per 100 foot build up rate (dogleg severity). It achieves this by the movement of two eccentric shafts relative to one another within the tool. These shafts are completely enclosed within a non-rotating stabilizer housing that maintains contact...
