Hydraulic fracture propagation in naturally fractured reservoirs: Complex fracture or fracture networks [PDF]

Journal of Natural Gas Science and Engineering, 2019
Understanding the behavior of fluid-driven hydraulic fracture in naturally fractured reservoirs is crucial in the development of geothermal energy and unconventional reservoirs. This study presents a fully-coupled numerical model to investigate hydraulic propagation in naturally fractured reservoirs, along with a comprehensive discussion on field ...

Fem Analysis of Proppant Sticking in Rock Cracks

Archives of Civil Engineering, 2018
The problem of effective gas extraction from Polish shale rocks is an interesting research subject for scientists. A properly selected proppant, which protects cracks from closing during the fracturing process, inestimably contributes to an increase of ...

Fractures of the distal radius (Colles' fracture) [PDF]

Sao Paulo Medical Journal, 2007
CONTEXT AND OBJECTIVE: Although Colles' fracture is a common clinical situation for the orthopedist, we did not find any information in the literature that would allow safe decision-making on the best treatment for each fracture type. The aim of the present study was to investigate Brazilian orthopedists' opinions regarding the main aspects of ...

Optimizing Composition of Fracturing Fluids for Energy Storage Hydraulic Fracturing Operations in Tight Oil Reservoirs

, 2022
Energy storage fracturing technology is a technical means by which oil displacement fluid is injected into the reservoir before the traditional hydraulic fracturing and subsequent implement fracturing. It provides a good solution for developing tight oil

Seismic studies of the unevenness of open fracturing and inhomogeneity of the fluid saturation in the geological environment for optimal development of oil and gas fields

Georesursy, 2018
The distribution of fracturing and the type of fluid saturation in the geological environment, along with its structure, is the most important information for optimal development of oil and gas fields, including their search, exploration and development.

Determination of stress state in deep subsea formation by combination of hydraulic fracturing in situ test and core analysis: A case study in the IODP Expedition 319

, 2013
[1] In situ test of hydraulic fracturing (HF) provides the only way to observe in situ stress magnitudes directly. The maximum and minimum horizontal stresses, SHmax and Shmin, are determined from critical borehole pressures, i.e., the reopening pressure

Research on the timing of polymer flooding oil and water well fracturing [PDF]

E3S Web of Conferences
Fracturing technology is the main measure to increase production and injection in oilfield production. With the gradual expansion of the scale of polymer flooding, the proportion of fractured Wells also increases year by year.

The politics of hydraulic fracturing in Germany : party competition at different levels of government

, 2016
Hydraulic fracturing has been practiced in Germany for decades, and several attempts have been made to legalize and regulate new drilling methods, which eventually led to the approval of a law to effectively ban this activity in 2016.
