.... The standard deviations Xi]) have been determined based on the typical literary variation coefficients (Table 1). Table 2 summarizes the values adopted. Figure 1 show the geological-geotechnical model adopted, considering the reduced water level. Table 1. Typical values of coefficient of variation Parameter...

... considered to be excavated simultaneously. Variation of principal stresses in the pillar zone and at the tunnel boundary have been studied in the analysis. The results have also been compared with the results of that excavation of a single horse shoe tunnel. It is concluded that for W/D = 0.3, in the case...

... such as variation in pore pressure can induce a response in the geomechanical behavior of the reservoir and thermodynamic behavior of fluid, which causes additional decrements on the flow capacity of the well drainage area. A procedure has been developed that determines the damage caused by changes in permeability...

Paper Number: ISRM-SBMR-2014-041
... Summary Traditionally, formation damage has been associated with the presence of a flow reduction around the wellbore area due to drilling and completion operations; however factors such as variation in pore pressure can induce a response in the geomechanical behavior of the reservoir...
