GYROGUIDE GWD70 Reduces EOU By 75% While Drilling, And 88% Using Memory Gyro Multishot
1 PagesA major operator is development drilling in the deepwater Atlantic through a thick salt zone (~2,000 m) - adding a considerable level of complexity to their offshore project. In the event of a blow out, the traditional method of using an active ranging technology to detect metal from the last casing shoe or drill pipe is not effective due to the high resistivity of the salt. A comprehensive contingency relief well plan with a stringent survey management component was required to safely drill each well with minimal risk, in addition to placing the pre-salt wells with extreme accuracy.
