Application of PEBI grid simulation to analyze pressure-transient behavior of hydraulically fractured vertical wells.
(2002)
Because of their flexibility while handling non-orthogonal systems, in this study, PEBI grids, implemented in a commercial simulator were employed to solve the mathematical models. However, it was first necessary to study ...
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 ...
Pore-scale Modeling and Multi-scale Characterization of Liquid Transport in Shales
(2018-12-14)
Distinct from conventional reservoirs, shale formations have limited pore connectivity and unique pore spatial-distribution. Consequently, theoretical pore-network models developed for conventional formations are not ...
BARITE SAG UNDER DYNAMIC AND ELEVATED TEMPERATURE CONDITIONS: EXPERIMENTAL STUDIES AND MATHEMATICAL MODELING
(2019-05-10)
Barite sag is an undesired occurrence that causes density variation in the wellbore. It is a problem that is related to both fluid property (mainly rheology) and drilling practices, and it arises mostly in invert emulsion ...
Optimization techniques for a multi-dimensional drilling model.
(1980)
The method of Hooke and Jeeves using Fibonacci line search has been used to solve the non-linear, multi-variable, unconstrained, objective function. A comparison between the Hooke and Jeeves searching method and other ...
THREE-DIMENSIONAL MODELING OF HYDRAULIC AND NATURAL FRACTURE INTERACTIONS AND ITS APPLICATIONS IN RESERVOIR STIMULATION
(2020)
The ultralow permeability of the unconventional and geothermal reservoirs can be increased for economic production by hydraulic fracturing. Natural fractures and other discontinuities are inseparable elements of unconventional ...
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 ...
Introducing the connected reservoir storage concept for reservoir characterization and production forecast
(2020-12)
This research presents a novel concept of the connected reservoir storage (CRSM) with which we can characterize the reservoir and accurately predict the production performance of hydrocarbon reservoirs, which have a complex ...
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 ...
Effects of resident water and non-equilibrium adsorption on the primary and enhanced coalbed methane gas recovery.
(2006)
This study presents an experimental and theoretical procedure to investigate the effects of the resident water and time-dependency of the sorption process on coalbed and shale gas primary and enhanced recovery by simultaneous ...
