(2017-12-07)According to the 2014 EIA statistics, natural gas production from shale and tight oil plays accounted for 48% of US natural gas production and this number is expected to grow to 69% in 2040. Natural fractures are commonly ...
-
(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 ...
-
(2011-10-21)Hydraulic fracturing is a popular stimulation method in tight gas and shale gas reservoirs that uses a viscous fluid to fracture the reservoir rock and uniformly transport proppant to create a highly conductive path that ...
-
(2017-05-04)Understanding how fractures propagate during multi-stage hydraulic fracturing enables better prediction for production and increases reserves. Fracture complexity from both stress shadow effects and natural fracture ...

DESIGN OF OPTIMAL PUMPING SCHEDULES TO ENHANCE OIL AND GAS PRODUCTION FROM UNCONVENTIONAL RESERVOIRS (2020-03-24)Hydraulic fracturing is a technique extensively used in the oil and gas industry, where water, proppant (sand) and additives are injected into unconventional reservoirs to enhance the recovery of shale hydrocarbon. Because ...
-
(2023-08-17)The primary focus of this thesis is to summarize a workflow that leverages 3D printing to generate repeatable rock conductivity samples, reducing uncertainty associated with experimental results. Study results illustrate ...
-
(2013-01-31)This work is about fracture conductivity; how to measure and model it based on experimental data. It is also about how to determine the relative importance of the factors that affect its magnitude and how to predict its ...
-
(2019-08-20)As water issues associated with hydraulic fracturing have received much attention, several optimization approaches have been developed for effective water management. However, most of them have not considered pumping ...
-
(2020-05-21)Creating sufficient and sustained fracture conductivity contributes directly to the success of acid fracturing treatments. The permeability and mineralogy distributions of formation rocks play significant roles in creating ...
-
(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 ...
-
(2019-04-05)The Eagle Ford (EF) Shale Play has been under intensive development for oil and natural gas production since 2011. This region is a major energy supplier to the United States and worldwide, currently producing over 1.2 ...
-
(2010-01-15)Productivity index (PI) is an important indicator of a well?s production capacity. For conventional reservoirs, well productivity is usually calculated using the pressure response of the reservoir in its pseudosteady-state ...
-
(2023-08-07)Controlled-source electromagnetic (CSEM) methods are inexpensive geophysical techniques that can be combined with petrophysical and petroleum engineering methods to improve our understanding of subsurface formation ...
-
(2010-10-12)Hydraulic fracturing plays an important role in increasing production rate in tight reservoirs. The performance of the reservoir after fracturing can be observed from the productivity index. This parameter is dependent on ...
-
(2018-08-09)Typically, the term shale oil refers to natural oil trapped in rock of low porosity and ultralow permeability. What has made the recovery of shale oil and gas economically viable is the extensive use of hydraulic fracturing. ...
-
(2015-11-24)Fracturing fluids are commonly formulated with fresh water to ensure reliable fluid rheology. However, fresh water is becoming more costly, and in some areas, it is difficult to obtain. Therefore, the use of produced water ...
-
(2017-12-08)As unconventional reservoirs continue to dominate the current economic climate, there is a great demand for developing innovative and efficient fracture treatment methodologies. Traditionally, the vast majority of hydraulic ...
-
(2018-08-03)Developing reduced-order models for nonlinear parabolic partial differential equation (PDE) systems with time-varying spatial domains remains a key challenge as the dominant spatial patterns of the system change with time. ...
-
(2011-02-22)Multiple transverse fracturing along a horizontal well is a relatively new technology that is designed to increase well productivity by increasing the contact between the reservoir and the wellbore. For multiple transverse ...
-
(2023-04-24)Numerical modeling of the hydraulic fracturing process is a complex and highly non-linear problem that requires special treatment of the far-field and the near-wellbore fracture propagation. In this study, I developed an ...
