    Author(s): Jawad Alshakban*, Wafaa Al-Shatty, Doaa Albaaji and Raffaele Romagnolid

    Dammam is one of the most tiresome formations that drillers challenge while drilling in the oil fields which located in South of Iraq and North of Kuwait. Therefore, the development of a geomechanical study may play a meaningful role in identifying the causes and establishing appropriate solutions to minimize the drilling cost. This research paper is to define the geostatic stresses, pore pressure, rock mechanical strength, elastic modulus and build one-dimensional mechanical earth model utilizing the most common failure criteria; Mohr-Coulomb, Mogi Coulomb and Stassi d’Alia. The best failure envelopes which anticipated the shear failure are Mogi and Stassi d’Alia in contrast with Mohr, while all criteria accord the same results with respect to the tensile failure. No laboratory test such as triaxial, uniaxial and Brazilian tests are available to be utilized for calibratio.. View more»
