Dual-porosity approach to wellbore stability in naturally fractured reservoirs.
(2002)
The naturally fractured reservoir was treated as a dual-porosity medium consisting of the primary rock matrix system and the fractured system. Assuming the matrix and fractures in the fractured medium to be 'separate and ...
Horizontal well productivity and wellbore pressure behavior incorporating wellbore hydraulics.
(2001)
This research reviews the equations used to determine horizontal well productivity, the models used for wellbore pressure, and develops a new method to estimate horizontal well productivity incorporating the effects of ...
Thermoporomechanical modelling of inclined boreholes.
(1998)
In the theoretical development part, a set of fully-coupled thermoporoelastic governing equations were proposed and some drawbacks in an existing model discussed. Formulae for stress- and temperature-dependent thermoporoelastic ...
Theoretical and experimental studies of power-law fluid flow in coiled tubing.
(2006)
Abstract not available.
Bottom hole analyses of gas kick (inflow) and gas reservoir characterization while drilling underbalanced.
(2005)
This study presents two new models developed to analyze gas flow between the reservoir and the wellbore while drilling underbalanced. Three drilling operational stages were considered in the analyses. These stages are the ...
A new conceptual approach to shale stability.
(1997)
Based on this broad investigation, the most probable instability mechanism is the creation of cracks with subsequent penetration of the drilling fluid into the fractures. An innovative conceptual model to analyze wellbore ...
