Theoretical Analysis of Proppant Embedment and Fracture Conductivity in Fractured Reservoir [PDF]
IOP Conference Series: Earth and Environmental Science, 2021 Abstract Proppant embedment mainly accounts for diminishing fracture aperture and conductivity. The conductivity decrease could greatly restrict fluid flow, thereby affecting the well performance. In this paper, new mathematical models are derived to calculate the proppant embedment and fracture conductivity after hydraulic fracturing ...

Investigation of the effect of gel residue on hydraulic fracture conductivity using dynamic fracture conductivity test [PDF]
, 2009 The key to producing gas from tight gas reservoirs is to create a long, highly conductive flow path, via the placement of a hydraulic fracture, to stimulate flow from the reservoir to the wellbore.

Effects of dispersion surfactants on the properties of ceramic – carbon nanotube (CNT) nanocomposites [PDF]
, 2014 Gum Arabic (GA), Sodium Dodecyl Sulfate (SDS) and their mixture were used for the dispersion of multi-walled carbon nanotubes (CNTs) in an alumina matrix. A good dispersion at low loadings (0.5-1 wt%) of CNTs in alumina was achieved by an ultrasonic bath

The Calculation of Coal Rock Fracture Conductivity with Different Arrangements of Proppants
Geofluids, 2018 An accurate evaluation of coal rock fracture conductivity is an important prerequisite for predicting the productivity of CBM wells. Coal rock is soft and fragile, with low elastic modulus and high Poisson ratio.
