Method and system for extending reach in deviated wellbores using selected vibration frequency
Pedro Miguel Nunes Pereira de Almeida Reis
A method for extending reach of a coiled tubing string in a deviated wellbore includes determining a frequency of vibration of the tubing string based on a function of the bending resonance of the tubing string and vibrating the tubing string at the determ ...
2018Experimental Investigation of the Aeroelastic Stability of an Annular Compressor Cascade at Reverse Flow Conditions
Compressor surge events are unsafe operating regimes yielding highly unsteady flow fields in which complex aeroelastic phenomena occur. If the blade flutter and forced response behaviour (i.e. aeroelastic stability) can be predicted reliably for normal flo ...
EPFL2012Stability of a leakage pathway in a cemented annulus
Brice Tanguy Alphonse Lecampion
The risk minimization of carbon dioxide (CO2) storage relies to some extent on well integrity assurance. While chemical reactions between the constitutive materials of the wellbore - such as cement - and stored CO 2 do not jeopardize the efficiency of a de ...
