Abstract

In this study, first the stability of a drilled well for oil production from a reservoir in the Asmary formation region of Iran using a finite different numerical method was assessed. Some sections of various well plunges were done. For each section, displacement, maximum major stresses, safety factor, and plastic zone condition around well using the mentioned numerical method were estimated. According to the results of the programme, summarized that the vertical well in relation to the horizontal well was in a better condition and in progressive of horizon the well may be unstable. Then the results of well stability analyses in various plunges were compared. Minimum and maximum horizontal stresses utilizing the Poro-elastic formula were calculated.
