Isolator Tool for High-Frequency Torsional Oscillation Proves Effective
This paper presents dynamic simulations, prototype testing, and field-test results of a BHA component that isolates the upper part of the BHA from HFTO.
Resolving Torsional Vibration in Limestone Reservoirs Reduces Equipment Damage
This paper examines multiple factors that can affect the severity of stick/slip and measures their actual effect.
New Rotary-Steerable System Delivers High Dogleg Severity, Improves Penetration Rate
A new rotary-steerable system (RSS) was designed to give geometrically greater dogleg-severity (DLS) capability while still being able to withstand the increased bending stresses.
Drilling Modeling and Simulation: Current State and Future Goals
The process of drilling a borehole is very complex, involving surface and downhole drilling systems that interact with the drilling fluid and the surrounding rocks.
