Optimization of fracturing parameters for tight sandstone gas reservoirs

IOP Conference Series: Earth and Environmental Science, 2021
Due to the poor physical properties of tight sandstone, the pore throat is small and the connectivity is poor. In the process of development, fracturing construction is often needed. Reasonable fracturing construction parameters are the key and difficult points of fracturing design, and also the key factor to determine the success of fracturing. Aiming

Permeability evolution during progressive development of deformation bands in porous sandstones [PDF]

, 2003
[1] Triaxial deformation experiments were carried out on large (0.1 m) diameter cores of a porous sandstone in order to investigate the evolution of bulk sample permeability as a function of axial strain and effective confining pressure.

A multi-scale geological–engineering sweet spot evaluation method for tight sandstone gas reservoirs

Natural Gas Industry B, 2023
Exploration and development practices have proved that staged volumetric fracturing stimulation in horizontal wells is a key technology for tight sandstone gas development, and reservoir sweet spot is an important basis for the perforation position ...

Influence of supercritical CO2 on the physical property of tight sandstone

Petroleum
In low-pressure gas reservoirs, water-based fracture fluid is difficult to flowback, which is unfavorable for several tight sandstone gas reservoirs in the Sichuan Basin with low pressure and high permeability geological characteristics.

Physical simulation on gas percolation in tight sandstones

Petroleum Exploration and Development, 2013
Capillary pressure was tested on 40 matrix cores (in situ permeability: 0.002×10−3–100 ×10−3 μm2) in the Sulige gas field and the pore structure features of different type sands were described finely. Based on the research on the pore structure features, gas percolation experiments were designed under the conditions of homogeneous cores with different ...

Petrographic characterization to build an accurate rock model using micro-CT: Case study on low-permeable to tight turbidite sandstone from Eocene Shahejie Formation [PDF]

, 2018
Pore scale flow simulations heavily depend on petrographic characterizing and modeling of reservoir rocks. Mineral phase segmentation and pore network modeling are crucial stages in micro-CT based rock modeling. The success of the pore network model (PNM)

Pore-scale characterization and modelling of CO2 flow in tight sandstones using X-ray micro-CT; Knorringfjellet formation of the Longyearbyen CO2 lab, Svalbard [PDF]

, 2014
Rocks of the Knorringfjellet Formation in Central Spitsbergen form a potential storage reservoir for CO2 below Longyearbyen. They are characterised by a moderate porosity and low permeability.
