In parallel, a conventional test is used to study the foam stability over these same ranges of surfactant concentrations, and seawater concentrations. The results...

... present challenges namely poor proppant transport, narrow fracture widths, and higher leakoff. These issues could lead to reduced fracture conductivity as compared to crosslinked fluids. The demand for alternatives to linear guar or crosslinked gels has led to the development of synthetic associative...

X-ray diffraction (XRD), scanning electron microscopy and energy-dispersive X-ray spectroscopy (SEM/EDS) analyses were also conducted to assess mineral composition, pore characteristics and distribution. The core...

... of these two shale plays are majorly based on the fracture conductivity, which may be dependent on the type of the geometrical shape of the fractures connecting the fluid to the well. A reliable model is desirable to the operator to accurately capture the productivity of multi-fractured shale wells. Several...

... production. Three factors, including well spacing, production pressure difference and fracture conductivity, influence the CO2 storage capacity. In operating an EGS, a larger well spacing, a lower injection temperature and a lower fracture conductivity are suggested. While the optimal production pressure...

... Abstract When rocks are fractured in tension, the fracture surfaces created are rough, with a wide range of surface morphologies possible. In previous studies of propped fracture conductivity using fractured samples, the fracture surface topography was found to have a strong influence...

... Abstract Nowadays, the only economic and effective way to exploit shale reservoirs is multi-stage fracturing of horizontal wells. The backflow after fracturing affects the damage degree of a fracturing fluid to a formation and fracture conductivity, and directly influences a fracturing outcome...

... in the laboratory. Results from the laboratory evaluation are validated with field production data. Standard ISO/API tests are adequate at comparing proppant types but do not accurately predict resultant conductivity in a well as they do not account for several in-situ damage mechanisms. With a limited number...

.... Preliminary results were encouraging and led to the development of two vibrational methods that substantially decreased gross variance of conductivity measurements. The cell loading technique outlined in API RP19D produced a variance ranging from 13% to 51%, with an average variance of 31% for the entirety...

In this case, history matching error response was most sensitive to rock-matrix permeability followed by fracture half-length. We then made 30-year production forecast using the most optimal solutions. Accepted solutions...

... Abstract As reservoir pressure decreases with production, the conductivity of hydraulic fractures will also change. These changes in fracture conductivity may impact well productivity significantly, so it is important to investigate the behavior of dynamic fractures. Also, characterzing...
