This newly developed formulation uses a combination of instant and delayed crosslinkers and additional stabilizing additives required at optimum concentrations to yield a stable fluid system in the treated seawater. At high temperatures, the addition of typical ion...

... (relative to depth) during fracturing treatment, which, in turn, normally causes breakout into and possibly through the lower stress boundary zones. Poor proppant placement and inconsistent areal proppant distribution leads to minimized proppant pack conductivity and ultimately productivity loss...

... ultimate recovery (EUR). Therefore, it is worth to identify optimal stage interval to stimulate horizontal lateral to cut costs through using the appropriate volumes of fracing fluid and proppant and to maximize profit by improving EUR. It should be noted that production from horizontal well...

...". The crosslink of the fluid can be delayed. It has excellent properties of proppant suspension. Oil production after stimulation using the new fluid increased 2-5 times compared with wells in similar locations. Gas production in multiple wells of the tight gas reservoir increased to 1.78×10 5 m 3 /d after...

... Abstract Optimization of conductive fracture area is perhaps the most critical tenets of fracture stimulation. Several attempts have been implemented to improve the effective fracture area, such as hybrid fracturing, ultra-lightweight proppant (ULWP) delivery, channel fracturing, and slug...

... on the surface and subsurface. Inlet, inside and outlet pressure of the blender should be concerned, because the blender utilizes non-mechanical pump, which requires sufficient motive flow to draw proppants into the main pipe, while the pressure difference directly impacts the flow rate of motive flow...

... more production rate. Based on some early production data of wells in Fushun-Yongchuan (herein after refer to as Fushun) block and its sensitivity analysis to completion parameters, it is found that the amount of injected fluid volume does not obviously impact the performance. Instead, proppant...

.... The fluid was tested for rheological properties, proppant-carrying capacity, retained permeability, and compatibility with formation fluid. To improve timing and efficiency of operations, multistage fracturing completion was used wherein each fracture sleeve was opened by dissolvable balls. Two sidetrack...

... Abstract Proppants are placed in fractures to provide highly conductive paths for hydrocarbons to flow from the reservoir to the wellbore. Hydraulic fracturing technology is constantly improving to achieve better production performance. Ultra-lightweight (ULW) proppants are one...

... tests showed that this chemical is also highly effective in controlling anhydrite scale in seawater-based fluid mixed with formation water that contains more than 20,000 ppm of calcium scaling ions. Proppant conductivity testing confirmed the fluid can be effectively cleaned up, leaving minimal proppant...

These features contain five aspects: well location and geometry, Bakken formation thickness, hydraulic fracture characterization, fracturing fluid, and proppant. 6 months' and 18 months' cumulative production were utilized to characterize the after...

... Abstract As an alternative to conventional proppant pack placement, propped pillar-fracturing promises more effective and conductive fractures by enabling hydrocarbons to flow through open channels. Recent experimental and numerical studies confirmed that viscous fingering phenomena can be used...

One study by Christie et al investigated the completion trends of four Montney operators since 2005 and showed the average completion interval length, the average number of fracture stages, and the volume of proppant used per fracture all increased over time. Al-Alwani et al, provided...
