Experimental Comparison between dynamic and static mechanical model of shale in Noor oil field/ New empirical correlations.

In recent decades, the oil industry has made advances in the geomechanical study of rocks, beginning with drilling operations, passing through reservoir studies, and concluding with production changes and hydraulic fracturing. Dynamic and static elastic models are utilized to analyse the behaviour of materials under various stress and strain conditions. Drilling into the Tanumah Formation in the Noor oil field faces various challenges that cause instability in the wellbore. For a comprehensive knowledge of the shale's mechanical process and to investigate the varying stresses at the deep subsurface, this study will analyze the mechanical properties of the shale in the Tanumah formation by making a comparison between the dynamic and static modulus. The study's results provide new empirical correlations for comprehending the behaviour of mechanical shale movement between static and dynamic Unconfined compressive strength, modulus of elasticity, Poisson’s ratio, bulk modulus and shear modulus.
