WELL CONTOL STRATEGY PLAN FOR BLOCK VIII, DINDIR ? SUDAN

Well control problems plagued the petroleum industry since it is infancy and known as losses of valuable resources, costs increasing, environmental damages, personnel casualtie s. The objective of this research is to develop well control strategy for block - 8 depending on Twakul - 1 well analysis of control problem occurred. Studying the wire line data to determine high pressure regions then confirm the pressure points data using we ll test data. Wire line data have been matches with each other justifying normal trend lines exist in subnormal region. Based on pressure analysis resulted balanced and safe mud weights were illustrated. Volumetric stripping method has been applied to kill the well. It is a complex technique combining volumetric method and stripping operation. It is worth mentioning; this method not common in the oil industry and is the first time to be applied in the Sudan. Well control strategy has been developed to help prevent and ease of dealing with such problems in future for Block - 8, Dindir - Sudan. This well control strategy include four sections as equipments, alarms, procedures and training at rig site. Finally ; it is a future prospective to have Sudanese well co ntrol, blowout and fire fighting strategies.
