Enhanced-Wellbore-Placement-Accuracy-Using-Geomagnetic-In-Field-Referencing-and-Multi-Station-Correction PDF 1

Reduced lateral spacing in congested oil and gas fields requires advanced techniques to prevent collisions while drilling. Anti-collision separation factors depend on the accuracy of the<br>steering technology employed. Geomagnetic In-Field Referencing (IFR) with Multi-Station (MS) correction improves lateral steering accuracy by about 50% . This technique enables the<br>drilling of straighter wellbores with fewer deviations and closer spacing.<br>Most horizontal wells are steered using measurement while drilling (MWD). The MWD tool in the bottom hole assembly (BHA) houses an accelerometer and a magnet
