• 1. NUMERICAL MODELING OF WELLBORE INSTABILITY (TENSILE FAILURE) USING FRACTURE MECH...

  » ABSTRACT     When a well is drilled, the equilibrium in situ stress is changed. In order to support the stress relief induced by the drilling and to prevent hydrocarbon influx into the cavity, the borehole is filled with a fluid. These operations create new stress configurations. The main point in wellbore projects is the definition of the drilling fluid density to keep the wellbore stable. The ...Continue Reading »

• 2. FRACTURE MECHANICS APPROACH FOR THE MAINTENANCE OF OFFSHORE OIL AND GAS PIPELINE

  » ABSTRACT Failure of offshore oil and gas pipelines occurs under certain conditions due to some applied mechanical forces. These conditions constitute a potential threat to the integrity of in service life span of the pipelines which can lead to loss of resources and environmental pollution. Several studies have shown that pipelines fail as a result of Welding, Fatigue Crack Growth, Corrosion Fatig...Continue Reading »
