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 ...
Influence of stress on the petrophysical properties of flow units in clean and shaly heterogeneous formations.
(1997)
The results show that increasing effective stress reduces the value of reservoir quality index under stress (RQIs) for clean formations. In addition increasing effective stress significantly reduces the value of reservoir ...
A laboratory study with a light crude oil to determine the effect of high-pressure nitrogen injection on enhanced oil recovery.
(1982)
Laboratory research was conducted to study displacements of crude oil by high-pressure nitrogen injection. The objectives of this research were to study the effect of temperature and gas-oil ratio in solution on crude oil ...
AN INTEGRATED GEOMECHANICS AND PETROPHYSICS STUDY OF HYDRAULIC FRACTURING IN NATURALLY FRACTURED RESERVOIRS
(2014-05)
Production enhancement of tight reservoirs requires in-depth analysis of mechanisms governing hydraulic fracturing, especially in naturally fractured reservoirs. This study is dedicated to the optimization of hydraulic ...
A coupled model for the prediction of fluid and reservoir properties from minifrac tests.
(1999)
A computer program was developed for the calculation of all parameters mentioned above and also to automatically curve-fit the main output and diagnostic plots of the model.
Seismic models of geopressured natural gas resevoirs /
(1983)
In order to study the seismic signatures of abnormally pressured sections, three different reservoir traps were modeled using a 40-Hz, zero-phase, Ricker wavelet and a two millisecond sample rate. MODEL A, CASES 1-2 involved ...
Study of multicomponent of hydrocarbon systems with molecular dynamics simulation
(2022)
Molecular Dynamics (MD) simulation is a powerful tool used in various research fields such as petroleum, geoscience, biochemistry, physics, and materials science. The unique merit of MD simulation is that it can investigate ...
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 ...
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 ...
