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 ...
In-situ stress determination in porous formation.
(1999)
Knowledge of the in-situ stress field is often critical in several aspects of well design, being one of the most important parameters in reservoir management: wellbore stability, hydraulic fracture propagation and production ...
Three-dimensional finite element modeling of two-phase fluid flow in deformable naturally fractured reservoirs.
(1998)
The developed theoretical formulation and numerical model are validated against several cases where the analytical solutions or other model results are readily available. The performance of the numerical code is tested ...
A dual-porosity model for two-phase flow in deforming porous media.
(1999)
In this dissertation, an approach, which is based on the dual-porosity concept and takes into account rock deformations, is presented to derive rigorously a set of coupled differential equations governing the behavior of ...
A coupled model for the prediction of interformation flow through an abandoned well.
(1998)
Application of the model is demonstrated in a computer program which is used to evaluate hypothetical field cases of varying producer/injector combinations and user defined abandoned well location and conditions. The results ...
Interpretation of horizontal well performance in multi-layer reservoirs by the boundary element method.
(1998)
The developed algorithm is applied to generate the dimensionless pressure and the dimensionless pressure derivative for a horizontal well in eight different systems whose analytical solutions are not available. These cases ...
Performance-decline curve analysis of vertical and horizontal wells in anisotropic and naturally fractured reservoirs.
(1999)
The research also introduces some novel approaches to estimating, from field production data, the simulation reservoir properties such as oil-water and gas-oil relative permeability relationships, PVT properties, and ...
Leak-off and cleanup behavior of fracturing fluids in the presence of mobile hydrocarbons.
(1997)
Leak-off characteristics in the presence of mobile gas or oil saturation are significantly different compared to those observed in the presence of 100% brine saturation. In the case of mobile gas saturation, the spurt loss ...
Simultaneous determination of relative permeability and capillary pressure from displacement data by simulated annealing.
(1998)
The requirements for unique estimation of the two-phase flow functions are investigated. The number of observable parameters is increased by including both the external and internal data. The flow functions are represented ...
A fully-coupled two-phase flow and rock deformation model for reservoir rock.
(1997)
In the application of most of the reservoir rock models to real engineering problems, the role of reservoir rock is frequently limited to its storage and delivery capabilities; the interaction of fluid flow with rock ...
