AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
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 ...
A method for extending reach of a coiled tubing string in a deviated wellbore includes vibrating the tubing string while the tubing string is injected into the wellbore at a first injection speed, finding the peak speed of lateral vibration of the tubing s ...
Robustness to formation geological heterogeneities of the limited entry technique for multi-stage fracturing of horizontal wells is investigated. It is necessary to simulate the complete process of initiation and propagation of multiple hydraulic fractures ...
The concept of CO2 storage relies on the long-term sealing properties of both the geological trap and the wells needed to inject and monitor CO2. Well integrity, a classical topic in the oil and gas industry, is thus critical for the performance of any CO2 ...
The integrity of the wellbore completion under injection conditions is vital for the effective, long term storage of carbon dioxide. Here we experimentally demonstrate and mathematically model fluid-driven debonding of the wellbore annulus in order to prov ...
