Unconventional Fracturing Fluids: What Where and Why
Unconventional Fracturing Fluids: What Where and Why

Fluid Retention, The major cause of productivity impairment in gas wells during drilling, completion and fracturing or workover operations is fluid, retention, effects. These can include the permanent retention of water or hydrocarbon based fluids or the trapping of hydrocarbon condensate

A mathematical model of multistage fractured horizontal well (MsFHW) considering stimulated reservoir volume (SRV) was presented for tight oil reservoirs. Both inner and outer regions were assumed as single porosity media but had different formation parameters. Different flow regimes were divided based on pressure transient analysis (PTA) curves. According to rate transient analysis (RTA), the ...

The ,Sulige gas field, is a typical low-pressure low-permeability tight sandstone ,gas, reservoir. The reservoir has poor seepage capacity, strong heterogeneity, high mineralization of formation water and extremely scarce water resources on the site. These unfavorable factors have brought great difficulties

1/3/2021, · ,The decrease of the peak at smaller values of the relaxation time, is small, which indicates that the flowback of fracturing fluid has been limited. Therefore, we can divide the fracturing fluid in the branch fracture into three types: free movable water in the fracture, restricted movable water under certain conditions, and retained water.
