Petrobras Improves Well Placement Using RSS Technology and Gyrosteering Capability

Publication Date: 09/07/2017

The gyrosteering capability of the PowerDrive Xcel RSS enabled Petrobras to sidetrack just 1 m below the casing shoe, achieve the full deviation from the pilot well after 16 m, and build inclination from 82° to 85° with a dogleg severity of 5 1/3°/30 m (even greater than the planned 3 1/2°/ 30 m) despite magnetic interference caused by the 9 5/8-in casing. GeoSphere reservoir mapping-while- drilling service enabled accurate drilling of an additional 866 m to achieve a total net pay of 643 m and exceed expectations for reservoir exposure.
