Paper Number: SPE-171577-MS
... by lithological properties of the rocks (Fredd et al. 2000). In addition, rough surface coupled with shear displacement causes closures of the fracture at some points and this eventually affects the proppant transport (van Dam and de Pater 1999). fracturing fluid single fracture proppant roughness...

...., it is not clear whether the MS observed in the field can be mainly attributed to local shear slip along natural fractures when leakoff occurs and/or induced by stress changes as a result of HF propagation or fluid leakoff). The exact slippage area and amount of slip displacement generating the microseimic event...

...) . Therefore no matter how complicated the wellbore curvature, the drillstring and the boundaries are, FEM can always obtain a solution. The drillstring is meshed into beam elements, each of which has six degrees of freedom (three rotations and three displacements). The only shortcoming of FEM...

... an elementary volume in the swept area during gravity dominated displacement under non-isothermal applications. We carried out two-phase (air-oil) and three phase (air-oil-initial water saturation) flow displacements in a capillary tube under isothermal and non-isothermal conditions, varying the air injection...

... the geomechanical response of the reservoir. By knowing the vertical displacement profile (VDP) at the top of the reservoir for the fine scale (truth) model and the VDP’s obtained from the listed techniques, the accuracy of considered EEM values is assessed. Sensitivity of change in VDP with respect to different...

... increased to 98 and 92 % OIIP, respectively. The waterflood oil recovery remains the same at 54% for both salinity levels indicating that dissolved CO 2 is the critical factor in oil displacement. Literature data suggests that CO 2 solubility in water increases when salinity of the injected water...

..., and possible, formation damage. Low-tension polymer flooding (LTPF) can be an alternative in these reservoirs. However, a major technical challenge in LTPF is that a fingered displacement front may occur. This instability reduces displacement efficiency and may invalidate normal method of simulating LTPF...

In addition, the propagation of strain displacement front as a wave, and the relevant changes in stress with time, can be tracked through the wave component of the geomechanics equations. We show the development...
