Thermo-mechanical analysis of wellbore stability in ultra-deep formations
Journal of Rock Mechanics and Geotechnical EngineeringWellbore stability is crucial for ultra-deep wells operating under high temperature and high stress conditions. To analyze the effects of thermal shock and horizontal stress on wellbore stability, a series of true triaxial compression experiments and ...

Wellbore stability in geomechanics [PDF]
Borehole instabilities can be encountered at any stage in the life of a well and they are the main cause of drilling difficulties, resulting in substantial expenditures, expensive loss of time, sometimes even in the loss of part of or even whole ...

Demulsifying agent simplified model for offshore oil wells
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This article addresses key challenges in offshore petroleum production caused by multiphase flow instabilities, such as slug flow and emulsion formation. Traditionally, severe slugging is mitigated by increasing wellhead backpressure through partial choke valve closure. In this context, a simplified dynamic model—the fast offshore wells model (

Investigation of wellbore stability in a North Sea field development [PDF]
, 2012 Planning drilling operations is key to the development of oil and natural gas fields. As part of well design, wellbore stability and pore pressure analysis are main factors in determining the safe operating window for selecting mud density.

Water‐based drilling fluids formulated with mature fine tailings
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Mature fine tailings (MFT) are persistent, highly stable colloidal suspensions generated as byproducts of bitumen extraction from oil sands. Given their environmental risks, identifying viable applications for MFT could reduce their accumulation while offsetting natural resource use.
