Hazards mitigation in carbonate super-reservoir drilling intervals
During the research it has been found that a considerable number of drilling hazards and complications with drill bit failures and mud losses is associated with abnormal reservoir layers. Regularities emerged from location of abnormal layers, their relationship with catagenetic processes was established, and a method was developed for forecasting possible complication zones based on core data on one well. To eliminate hazards in well drilling, we suggest using a model forecasting real depth of occurrence of hazardous layers. This can help to implement deep and ultra-deep well drilling program, incorporating technical solutions aimed at prevention of complications.
