Geomechanical Modeling of In-Situ Stresses Around a Borehole [PDF]

, 2002
In this paper, we present a modelling of the in-situ stress state associated with the severe hole enlargement of a wellbore. Geomechanical information is relevant to assure wellbore stability, i.e., to prevent damages in the formation and later on ...

Prediction of Gas–Liquid Two‐Phase Flow Pressure Wave in the Wellbore During the Re‐Production of Deep Gas Wells

Energy Science &Engineering, Volume 13, Issue 11, Page 5105-5120, November 2025.
Prediction of gas–liquid two‐phase flow pressure wave in the wellbore during the re‐production of deep gas wells. ABSTRACT The pressure of the tube at the wellhead is abruptly released during the opening of a high‐production gas well, causing pressure fluctuation and subjecting the tubing to extra stress.
