As a result of the analysis, limitation of PTA models, related, for example, to the non-uniform fracture conductivity and the lack of interflow between layers with different properties, as well as the fracture design...

... a mathematical model of proppant embedment, which makes it possible to estimate the change in the fracture conductivity. A joint calculation of the stress and pressure fields is carried out. The stress values are used to check the conditions at the start of proppant embedment. The discussed example shows...

... Abstract The channel fracturing technique changes the concept of proppant fracture conductivity generation by enabling hydrocarbons to flow through open channels instead of through the proppant pack. The new technique is based on four main components: proppant pulsing at surface with fracturing...

.... In comparison with conventional proppant, it provides higher fracture conductivity with integrated flowback control due to random alignment of proppant grains while packing. This property results in improved fracture cleanup from treating fluids. The rod-shaped proppant also acts to prevent proppant flowback...

... Abstract In the last two decades, hydraulic fracturing has become a routine completion practice in most oilfields producing from the low- and medium-permeability Jurassic formations in western Siberia. To optimize hydraulic fracture conductivity, operators and service companies were...
