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 ...
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 ...
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 ...
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 ...
Analysis and Control of Stick-Slip using a Scaled Experimental Drilling Rig
(2023-08-04)
Drilling is one of the most challenging and expensive processes involved in oil and gas production. Due to the destructive nature of the drilling process, dysfunctions are common during drilling. These dysfunctions can ...
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.
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 ...
Three Dimensional Thermo-poroelastic Modeling of Fluid Injection and Induced Microseismicity in Naturally Fractured Reservoirs
(2018)
Interests in naturally fractured reservoirs have grown rapidly in recent years due to the increasing energy needs. Understanding the behavior of naturally fractured reservoirs would be beneficial for a variety of engineering ...
