(2016-05-26)Due to the extensive technically recoverable shale natural gas resources and an increase in production from shale plays over the last 10 years, it is essential to focus on stimulation techniques to enhance productivity in ...
-
(1976)Part I. Through a literature search on the mechanics of thrust faulting, I have found that reduction of the effective downward stress component of the overburden pressure due to abnormal fluid pressures in the subsurface ...
-
(2013-09-29)Two methods of hydraulic fracturing most widely utilized on unconventional shale gas and oil reservoirs are “gelled fracturing” and “slick-water fracturing”. Both methods utilize up to several million gallons of water-based ...
-
(2017-12-11)In this work, a modified workflow for incorporating molecular effects into a macroscopic fluid flow model via a mesoscopic transition model to more uniformly ascertain transport properties during pore scale analysis, is ...
-
(2021-04-29)Microstructure of a material determines the transport, chemical and mechanical properties. Geological materials and geomaterials are imaged using microscopy tools. The microscopy images are analyzed to better understand ...
-
(2019-06-10)Source rocks, such as organic-rich shale, consist of multi-scale pore structures which include pores with sizes down to nano-scale contributing to the storage of hydrocarbons. During my Ph.D. studies, using molecular ...
-
(2012-10-19)There is a huge demand in the industry to forecast production in shale gas reservoirs accurately. There are many methods including volumetric, Decline Curve Analysis (DCA), analytical simulation and numerical simulation. ...
-
(2019-06-10)Shale swelling causes 90% of wellbore instabilities and oil-base muds (OBM) have been the best choice for many years. However, the stringent environmental concern have resulted in a keen interest in the development of ...
-
(2015-07-08)In this work, a dynamic permeability model for organic-rich shale matrix is constructed and implemented into a flow simulation to investigate the impact on production. Effective stress and molecular transport effects on ...
-
The Effect of Proppant Size and Concentration on Hydraulic Fracture Conductivity in Shale Reservoirs (2013-04-11)Hydraulic fracture conductivity in ultra-low permeability shale reservoirs is directly related to well productivity. The main goal of hydraulic fracturing in shale formations is to create a network of conductive pathways ...
-
(2016-05-04)Unconventional reservoirs have become increasingly possible and economical due to the advances of hydraulic fracturing, a stimulation technique that creates highly conductive fractures that serve as pathways for hydrocarbons ...
-
(2015-05-12)Production of hydrocarbons from low-permeability shale reservoirs has become economically feasible thanks in part to advances in horizontal drilling and hydraulic fracturing. Together, these two techniques help to create ...
-
(2021-04-29)In recent years, the rapid decline in the production trend of liquid-rich shale reservoirs calls attention to enhance oil recovery (EOR) methods. One of the most promising EOR methods in unconventional reservoirs is a ...
-
(2018-03-30)Whole-rock elemental data is a useful tool for sub-dividing and characterizing mudrock variability across a shale basin. The chemostratigraphy of the Cenomanian-Turonian the Woodbine and Eagle Ford Groups in the Brazos ...
-
(2017-12-13)Interest in applications of x-ray fluorescence (XRF) is greatly increasing, but the diversity of applications of XRF data has yet to be fully exploited. This dissertation presents three projects showcasing different ...
-
(2021-12-07)Previous experimental studies and limited field results have shown that the application of surfactants can be effective in improving recovery from unconventional liquid-rich reservoirs. Most of these studies and field ...
-
(2022-04-19)Carbon capture and sequestration processes can use the infrastructure of unconventional EOR projects targeting organic-rich source rocks and use the existing fluids separation and injection technologies. Accordingly, source ...
-
(2021-04-23)A micro-scale investigation of mechanical rock properties is carried out in this study. Two of the main mechanical properties being investigated are rock elastic properties, identified by the Transversely Isotropic (TI) ...
-
(2018-01-19)The first part of this work proposes a partitioning scheme to divide porous media in shale into three different sub-media (porosity systems) with distinctive characteristics: inorganic matter and kerogen (in the shale ...
-
(2014-04-04)Shale gas reservoirs with multistage hydraulic fractures are commonly characterized by analyzing long-term gas production data, but water flowback data is usually not included in the analysis. However, this work shows there ...
