(2019-11-25)The interactions between hydraulic fracturing fluid at lower temperature and salinity with the formation a cause non-uniform stress field. The formation experiences heat transfer to the fracture and local change in ...
-
(2016-04-29)In hydraulic fracturing stimulation treatments for organic-rich mudrocks, some issues that pose challenges in pre-completions design include selection of intervals for stimulation treatment, and selection of proppants for ...
-
(2014-10-16)From September 2011 to July 2013 the percentage of flared associated gas produced in the Bakken shale formation decreased from 36% to 29%. Although the percentage decreased, the volume of associated gas produced has almost ...
-
(2017-08-02)The main focus of this work was to study formation damage during shut-in time and production following hydraulic fracturing a gas shale formation. More specifically, this work investigated numerically the intricate effects ...
-
(Texas A&M University. Libraries, 1989)Isochronal testing of gas wells suggests that high velocity flow in wells containing hydraulic fractures results in an additional pressure drop down the fracture that is flow rate dependent. In addition, wellhead pressures ...
-
(2017-06-28)Proppants are solid particles, extensively used in hydraulic fracturing operations. These materials possess specific mechanical strength indispensable in keeping induced fractures open, resulting in up-surged well production. ...
-
(2018-11-27)The activation of natural fractures and associated microseismicity generation and radiation during hydraulic fracturing treatments are dynamic processes. However, most of the current hydraulic fracturing models are based ...
-
(2018-07-17)The present experiment attempts to study the behavior of proppant mixed with fibers in slickwater fracturing using a large-scale flow equipment. Previous experiments have shown that, at small scale, PGA fibers in slickwater ...
-
(2017-08-31)Hydraulic fracturing has become a common practice in the petroleum industry. Polymers are the main components of fracturing fluids, but high polymer loadings can leave more residue after the treatment. Therefore, crosslinkers ...
-
(Texas A&M University. Libraries, 1979)Laboratory hydraulic facture experiments are conducted on monolithologic and dilithologic layered rock specimens as a function of interfacial normal stress to determine the relative influence of the interfacial shear ...
-
(2022-07-28)In unconventional shale formations where the horizontal bedding planes and laminations prevalently exist, the height propagation of a vertical hydraulic fracture is not only affected by the conventional factors such as the ...
-
(2022-06-03)Unconventional shale gas production in the United States has been largely improved due to the development of hydraulic fracturing technology. However, the shale gas production system is generally complex; further, such ...
-
(2023-04-13)Low-frequency distributed acoustic sensing (LF-DAS) can be used as a monitoring tool for hydraulic fracture propagation using measured values of strain. To understand subsurface conditions with shear and normal stresses, ...
-
(Texas A&M University. Libraries, 1985)The influence of material anisotropy (transverse isotropy) on half-plane surface tilt and displacement fields induced by a near-surface crack under uniform pressure or shear is investigated by solving a series of boundary ...
-
(2020-01-29)In hydraulic fracturing, the proppant-filled fracture length at the end of pumping strongly influences the fluid conductivity of natural oil and gas. Therefore, it is very important to regulate proppant bank height and ...
-
(Texas A&M University. Libraries, 1977)This research was performed to find the effect of non-Darcy flow of gas in fractures on reducing well productivity. The concept of Wright utilizing four flow regimes to describe flow in porous media was applied in this ...
-
(2017-12-08)Horizontal wells with multistage hydraulic fractures (HFs) are required for maximizing the oil and gas production from unconventional reservoirs. Since the characterization of complex fracture geometry with high accuracy ...
-
(2015-04-27)Water-based fracturing fluids contain polymers to function either as fluid viscosifiers or friction-reduction agents. Whereas much work has been done on optimizing these functions, little or no published work focuses on ...
-
(2019-03-07)This dissertation proposes a workflow for modeling of multistage hydraulic fracturing stimulation in unconventional formations. Based on the field case of a horizontal well targeted lower Wolfcamp formation in Midland ...
-
(2019-07-03)This dissertation includes three essays in environmental and resource economics. The first two pertain to important topics in relation to the upstream oil and gas industry in the U.S. The third pertains to marine recreational ...
