Paper presented at the SPE Norway Subsurface Conference, April 17, 2024
Paper Number: SPE-218431-MS
... drill-string configurations were explored, considering complex geometries, such as buckled drill-string (Erge et al., 2015). At this point, it was stated that pipe rotation has a major effect on pressure losses - and that dynamics effects seem to dominate compared to other geometrical characteristics...

... transferring rotational torque from a top drive. The team designed and created a bi-directional hydraulic swivel, BHA, and a custom drill bit. Steering was achieved by changing the fixed bend BHA orientation by rotating the drill pipe. A nonlinear Model Predictive Controller (nMPC) was used to allow long-term...

...) system is based on the Moineau concept, which uses powered rotor/stator device to move the fluids. PDM traps some volume of the drilling fluid and forces it out (displaces), transmitting power, which allows the assembly to rotate the drill bit. Such systems could be used in all sections of the well: kick...

... no rotation was possible and with an openhole section up to ±13,500 ft, there was a highlighted risk of packing off and going on losses during the cement job. To accommodate this risk, large excess cement volumes were planned and reciprocation was evaluated. In this field, reciprocation of the string has...

Paper Number: SPE-173840-MS
... Abstract A computational fluid dynamics (CFD) analysis is conducted on the flow of Newtonian and non-Newtonian fluids in annuli including the effect of inner pipe rotation. A practical numerical model is proposed that accurately estimates the annular frictional pressure losses with and without...

... successfully in other countries. The turbine power shoe provides the ability to rotate a reamer shoe without rotating the whole string from surface, while it requires limited changes to the liner string and running parameters. It is an additional tool to cross ledges and unstable intervals. The tool has been...
