Paper Number: SPE-195220-MS
... concentration and length of 2 nd MFs—helped improve the effective MF conductivity in a linear manner; the highest proppant concentration and the 2 nd MF zone resulted in the highest fracture conductivity achieved. Insight obtained from this study can be used to optimize fracturing designs by including UFPs and...

Paper Number: SPE-195221-MS
... To simulate the hydraulic fracturing process for a single fracture stage, 112 m 3 of stimulated fluid at 49 degC are injected for 1.5 hours into the fracture through the horizontal wellbore. The well is shut-in for 10 days (warm-back) before starting to produce (flow-back). Figure 2 shows the...

... diffusion is regarded as critical for gas Huff and Puff process of tight oil reservoirs. Utilizing the dual permeability model, gas diffusion effect is systematically analyzed and compared with the widely used single porosity model to justify its importance. Transport in natural fractures is proved to be...

Paper Number: SPE-195193-MS
... Abstract Engineers commonly expect symmetric fracture wings in multiple transverse fracture horizontal wells (MTFHWs). Microseismic surveys have shown asymmetric hydraulic fracture grow away from the recent fractured wells and grow towards previous produced wells. It might be caused by the...

... elastic properties of Young’s Modulus (YM) and Poisson’s Ratio (PR) to derive a relationship to define rock brittleness indicator. They combined rock elastic properties of YM and PR to reflect the ability of the rock to fail under stress (Poisson’s Ratio) and maintain a fracture (Young’s Modulus) once the...

Paper Number: SPE-195203-MS
... Abstract Due to the layered texture and sedimentation environment, shale formations usually characterized as high heterogeneity and anisotropy in in-situ stresses. During the hydraulic fracturing process, fracturing fluid is injected at a pressure above the formation pressure. This injection...

... Abstract Production logs from horizontal wells in shale reservoirs indicate that more than 30% of the perforation clusters do not contribute to production. One major reason is recognized as the stress shadow effect which impedes the propagation of the interior fractures within a single fracture...
