A key feature of geomechanical modeling for hydraulic fractures aims or self-induced fracturing in mature fields is the estimation of reservoir pressure, particularly in the vicinity of production and injection wells. In addition, this has a significant impact on stress anisotropy, which is the primary factor affecting the geometry of the hydraulic fracture and the surrounding induced stress field. It is also crucial to monitor geomechanical core studies, ensure quality control of samples, and accurately process research results since the profiles of elastic-strength properties and stresses depend on these factors. This paper also addresses fracturing, including its measurement, calculations, and the prediction of its spatial orientation and intensity.</p>geomechanicsanisotropystress polygonhydraulic fracturing gradientwellbore stabilityhydraulic fracturing portfracture lampsгеомеханикаанизотропиякернеу полигоныҚГЖ градиентіұңғыма оқпанының тұрақтылығыГРП портыжарықшақтық тығыздығыгеомеханикаанизотропияполигон напряженийградиент ГРПустойчивость ствола скважиныпорт ГРПплотность трещиноватости1.Morrill JC, Miskimins JL.
