Risk assessment and management objective is to maximize the probability of a project’s successby identifying, analysing, mitigating and controlling the risks.The goals of the drilling managementengineers team is to work with drilling clients to significantly reduce cost, time and non productive timethrough integration of planning and real time drilling solutions. During drilling, deformation occurred to9⅝'' casing in Well AG-1, Well AG-2 and Well AG-3 in Abu Ghirab oilfield. Casing deformation wasdiscovered while running Bottom Hole Assembly (BHA) and tools in the hole as they got an obstructionand stuck due to 9⅝ inch casing deformation in Lower Fars formation This study includes an investigation,analysis and designing new specifications of 9⅝ inch casing using Landmark software. Results ofinvestigations showed poor in cement evaluation practices. Formation integrity tests (FIT) and CasingIntegrity Tests (CIT) has not been implemented and Cement Bond Log (CBL) or Segmented Bond Tool(SBT) log has not been running in the hole. The proposed new casing design; increase casing weight, changecasing grade, change casing thread type and increase casing design safety factor of collapse and burst load,can avoid the impact of salt creeping on 9⅝'' casing. Applying best available technology and drilling riskmanagement to reduce drilling cost and minimize time by mitigating or preventing drilling problems.
