Laboratory Evaluation Of Chemical Grouts for Wellbore Stabilization
Proceedings of Nigeria Annual International Conference and Exhibition, 2003Abstract Wellbore drilling in highly fractured and unstable formations has always been one of the greatest difficulties in drilling operations. Failure and collapse of wellbore wall frequently occur in the fractured zone and may ultimately obstruct any further drilling of the wellbore. A number of techniques have been proposed and tested

Wellbore Stability in the Olmos Formation
2016Wellbore stability is crucial for optimizing production and maintaining safety for any given oil and gas extraction site. A stable wellbore will reduce potential rock failures and as a result, eliminate remedial costs for the company associated with wellbore collapse. An unstable wellbore can negatively affect production.

Quality Assurance of Wellbore Stability Analyses
SPE/IADC Drilling Conference and Exhibition, 2011Abstract It has become clear that many wellbore stability studies suffers from various inconsistencies. These lead to incorrect results, or results that may not be extrapolated to other well configurations. In this paper typical wellbore fracturing and collapse models are investigated with respect to the accuracies in the ...

Stability evaluation SCB-01 wellbore
2018The goal of this note it to evaluate the behaviour in the well and the interaction of the flowline and well system. This translates into three questions: Q1: Does the well slug by itself? Q2: Is there any interference from the flowline (if the flowline is slugging, is this noticed in the well)?

Stability modelling applied to wellbore design
2008When a well is drilled in a hydrocarbon reservoir, the thermodynamic equilibrium of virgin rocks is altered, the natural stresses are redistributed, and a stress concentration occurs around the hole. The alteration of original equilibrium can lead to wellbore yield, evidenced as shear banding and dilatation, circumferential crack, and microfissuring ...
