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 ...
INTERWELL CONNECTIVITY TESTS IN WATERFLOOD SYSTEMS
(2009)
Well testing is a common and important tool of reservoir characterization. Many well testing methods have been developed in order to obtain different reservoir properties. Interference tests and pulse tests are used to ...
Effect of pressure depletion on hydrocarbon recovery in naturally fractured reservoirs.
(2006)
The link between well test analysis, the material balance equation, and the elastic properties of the rock resides in the fluid storage capacity. Thus, in this study, the influence of stress on the mechanical behavior of ...
Nuclear magnetic resonance (NMR) study of freezing and thawing of saturated porous media and application to shale and pore volume compressibility estimation.
(2007)
Conventional logging tool response is complicated by the presence of shale making it difficult to interpret the log response. Water saturation in shales assumes the shales are filled with brines found in nearby sands. In ...
NON-NEWTONIAN POWER-LAW FLUID FLOW IN ECCENTRIC ANNULI: CFD SIMULATION AND EXPERIMENTAL STUDY
(2009)
Numerous publications have addressed the problems inherent to calculating wellbore hydraulics in eccentric annulus. The challenge of theoretical and numerical studies of fluid flow in an eccentric annulus is mainly due to ...
