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.

Conductivity and Transmissivity of a Single Fracture [PDF]
Transport in Porous Media, 2018 The effective flow and conduction properties of fractures with Gaussian spatial correlations are investigated by solving the microscale governing equations in three-dimensional samples, along the lines initiated by Mourzenko et al. (J Phys II(5):465–482, 1995), Volik et al.

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 ...
