Analysis of the Algorithm Monitoring the Geometric Parameters of the Powered Support Based on Station Tests

Energy Science &Engineering, EarlyView.
ABSTRACT The powered roof supports in the longwall complex are placed and interconnected next to one another, typically about 125–250 units in a longwall face. It is an essential component in the longwall complex, which also includes a shearer (or plow) and an armored face conveyor.

Quantifying Parametric Influence on Cuttings Transport in Deviated Deep Wells Using Global Sensitivity Analysis Methods

Energy Science &Engineering, EarlyView.
Cuttings transport simulation workflow. ABSTRACT Efficient cuttings transport is essential for wellbore stability and minimizing non‐productive time in deviated and horizontal wells. This study applies global sensitivity analysis (GSA) to evaluate the influence of 14 drilling parameters on cuttings transport using WellPlanTM hydraulic simulations ...
