TOWARDS A BETTER UNDERSTANDING OF THE RELATIONSHIP BETWEEN MOLECULAR FORCE AND HYDROCARBON RECOVERY
(2019-08-01)
The optimization of hydrocarbon recovery is the core of petroleum engineering. Experiments are always the go-to approach to reveal mysterious observations and verify new theories. However, recent advances on our understanding ...
NEW AND IMPROVED TECHNIQUES FOR CHARACTERIZING BRITTLE ROCK RESPONSE
(2017-12)
To improve the production from shale, stimulation technique such as hydraulic fracturing with proppants is essential. To maximize the effectiveness of hydraulic fracturing, brittle intervals with the minimum creep deformation ...
Dual-Porosity and Dual-Permeability Poromechanics Solutions for Problems in Laboratory and Field Applications
(2010)
In this work, a study of anisotropic dual-porosity and dual-permeability poromechanics is presented through generalized analytical solutions for selected problems in laboratory and field applications. For example, the ...
INVESTIGATION OF OILWELL CEMENT MIXING: EXPERIMENTAL STUDIES AND IMPLICATIONS FOR MIXING ENERGY THEORY
(2018-05-11)
Cement is a key element of wellbore integrity. Mixing condition for cement and how its properties are affected is of great importance but often ignored in the oilwell cement design. Typical cement slurry properties such ...
Numerical Simulations of Fracture Propagation Applied to Petroleum and Geothermal Reservoir Using Finite Element Method
(2015-08)
Hydraulic fracturing is a major technique in reservoir stimulation to enhance production. Better understanding of mechanisms of hydraulic fracturing is essential for designing hydraulic fracture treatments. Multiple physical ...
Chemical Flood Under High Total Dissolved Solids (TDS) Conditions
(2014-08-15)
After the primary and secondary production, there is still a great potential of enhanced oil recovery (EOR). Currently, the high oil price, increase of oil demand and maturing oil fields and the improvement in surfactant ...
Poroelastic After-Closure Pressure Decline Analysis In Dual-Porosity Dual-Permeability Formations
(2016)
The dual-porosity and dual-permeability theory of poroelasticity is used to analyze the wellbore dual-pressure responses of dual-porosity or naturally fractured formations. The pressure decline is analyzed by modeling the ...
CARBONACEOUS NANOSIZED SURFACTANT CARRIERS AND OIL-INDUCED VISCOELASTIC FLUID FOR POTENTIAL EOR APPLICATIONS
(2018-05-11)
This dissertation aims to advance the conventional tertiary oil recovery method, surfactant flooding process. Via injecting a finite slug of surfactant-only or mixture of surfactant/polymer solution into reservoir, surfactants ...
FUNDAMENTAL INVESTIGATION OF PRE-EXISTING FRACTURE SLIP AND PROPAGATION IN RESERVOIR STIMULATION
(2019-12)
The deformation behavior and transport properties of subsurface reservoir rock masses are highly influenced by the existence of natural fractures. Shear reactivation of pre-existing fractures by pressurized fluid injection ...
MATRIX HETEROGENEITY EFFECTS ON FLUID TRANSPORT IN POROUS MEDIUM: USING PERTURBATION THEORY
(2010)
In this dissertation the processes of transport and reaction in heterogeneous porous medium is upscaled from pore scale to the scale of interest (e.g., core sample or reservoir scale) and new governing equations describing ...
