Abstract
Determination of In-situ stress domain in oilfields is so important for drilling, well completion and petroleum geomechanics. Simply, determination of magnitude and direction of In-situ stress around wellbore is the first step of geomechanical studies and wellbore stability particularly. Preliminarily, because of importance of casing collapse problem in the Marun oilfield, the magnitude of in-situ stress is determined. The magnitude of vertical stress (Sv) was in range of 85 to 90 MPa. The minimum horizontal stress (Shmin) determined by some analytical methods. For estimating of maximum horizontal stress (SHmax) domain we used Anderson’s faulting theory and stress polygon. So the magnitude of SHmax was so close to Sv and the faulting regime shows normal/strike slip. Within Gachsaran Formation in depth of collapses because of salty lithology and high pore pressure, magnitude of In-situ stress is so close and it can be assume hydrostatic stress state.
