This work proposes a strategy for the robust optimization of the nonlinear dynamics of a drill-string, which is a structure that rotates and digs into the rock to search for oil. The nonparametric probabilistic approach is employed to model the uncertainties of the structure as well as the uncertainties of the bit-rock interaction model. This paper is …

Predicting and evaluating penetration rate (ROP) in real-time drilling operations has been a long-standing challenge. This paper proposes a machine learning-based approach that combines LSTM architecture and attention mechanism to achieve a more accurate and stable prediction of ROP, meeting the practical needs of ROP …

a higher penetration rate with the same blunt tool till the penetration rate drops appreciably and the bit starts grind-ing the rock instead of cutting. This operational difficulty necessitated further research into the performance of drill bit under varied thrust to maintain the drilling rates at opti-mum levels and maneuver the field conditions.

After the positive results on the SKF test rigs, the bearings were put into operation on a customer test rig in an application with an axial load of 310 kN. The customer's previous best-case performance for the bearing was 63 hours MTBF. The SKF redesigned mud bearing test was stopped at 86 hours and examined for wear.
