Analytic Modelling for Wellbore Stability Analysis

Procedia Structural Integrity, 2017
Abstract 1D geomechanical model based on cross-dipole wideband acoustic logging for unconventional reservoir is calculated. TIV anisotropic zones were highlighted and corresponding anisotropic elastic properties were confirmed by core samples tests.

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 ...

Research on vertical structure stability before cementing ultra-deep wellbore by drilling method

Meitan xuebao
To address the problem of vertical stability of ultra-deep wellbore by drilling method, firstly, the results of the equation of critical height of equal section for non-full counterweighted water drilled wellbore are compared with the results of the ...

Model of horizontal stress in the Aigion10 well (Corinth) calculated from acoustic body waves

, 2006
In this paper we try to deduce the in situ stresses from the monopole acoustic waves of the well AIG10 between 689 and 1004 meters in depth (Corinth Golf).
