Successful Application of Vertechs ULIA Wellbore Strengthen Material in HTHP Well, Gaomo Block, Sichuan
In June 2018, Vertechs ULIA wellbore strengthen material was applied to a HTHP well in Gaomo block, Sichuan. With this application, drilling operators were able to successfully penetrate the thief zone and drill 19,500 ft to the design depth with another 980ft extension.Potassium polysulfide water-based mud system was used to drill the reservoir at downhole temperature of 285 degF. Frequent mud leakage was encountered during the drilling of offset wells in the same formation layer. Loss of circulation materials were used
