A method for predicting fracture conductivity based on three‐dimensional spatial morphology features
Energy Science & Engineering, 2023 The distribution of fracture clearance is an important factor that determines the conductivity of carbonate fractures. In this paper, the morphological analysis of acid fractures and the evaluation of acid fracture conductivity were carried out to test ...

The effect of combined proppants upon the fracture conductivity in tight gas reservoirs
Energy Reports, 2020 Sand and ceramic proppant are the most commonly used materials to keep fractures open during hydraulic fracturing. Ceramic proppant has higher hardness and sphericity than sand, but it is much more expensive.

Hydraulic conductivity of rock fractures [PDF]
Transport in Porous Media, 1996 The flow of a single-phase fluid through a rough-walled rock fracture is discussed within the context of fluid mechanics. The derivation of the ‘cubic law’ is given as the solution to the Navier-Stokes equations for flow between smooth, parallel plates - the only fracture geometry that is amenable to exact treatment. The various geometric and kinematic

Water Saturation Calculation and Fracture Type Identification of a Buried Hill Fractured Reservoir
Lithosphere, 2021 A buried hill reservoir is a special type of bedrock reservoir, in which fractures are the important reservoir space and main percolation path. However, due to the characteristics of the buried hill reservoir such as deep burial depth and high formation ...

Rate Transient Behavior of Wells Intercepting Non-Uniform Fractures in a Layered Tight Gas Reservoir
Energies, 2022 RTA (Rate Transient Analysis) is a valuable method for obtaining reservoir parameters and well performance, but current RTA models hardly consider the MLVF (Multi-Layer Vertical Fractured) well in a layered tight gas reservoir.
