The MVSD2015 and MVHD2015 are higher definition alternatives to the BGGM and HDGM global models respectively. For additional information, please follow the links below:

MagVAR Standard Definition Model (MVSD) MagVAR is now introducing the new MVSD2015 global geomagnetic reference field model. The MVSD is MagVAR’s standard definition model of the Earth’s main field and updated annually in order to capture secular changes. The MVSD is a higher definition alternative to the BGGM model and satisfies the conditions of the ISCWSA MWD error model tool code. |

MagVAR HIgh Definition Model (MVHD) MagVAR is now introducing the new MVHD2015 global geomagnetic reference field model. The MVHD is MagVAR’s high definition model of the Earth’s main field with a crustal field component and updated annually in order to capture secular changes. The MVHD is higher definition alternative to the HDGM model and satisfies the conditions of the OWSG MWD+HDGM error model tool code. This higher accuracy model gives drillers the advantage of reduced ellipses of uncertainty than those achieved with the BGGM model making the MVHD a great solution to increase separation factors when anti-collision planning. |
