Specialists from the Moscow Scientific Institute of Rosneft, together with the Geophysical Center of the Russian Academy of Sciences, created a new geomagnetic model (GMM) with a resolution of 38 km. It allows you to accurately predict the parameters of the Earth’s magnetic field and control the trajectory of well drilling, which is especially important for the oil and gas industry.\u00a0<\/p>\n\n\n
A geomagnetic model is a mathematical description of the planet\u2019s magnetic field in a quiet state. It helps to track its changes at any point and predict future fluctuations. This data is used not only in science, but also in industry, for example, in directional drilling.\u00a0<\/p>\n\n\n
Every year the model is refined by adding new data. There are different versions such as IFR1 and IFR2. The first takes into account local anomalies of the earth’s crust, and the second takes into account rapid changes in the external magnetic field. According to experts, the model resolution can be increased to 28 km.\u00a0<\/p>\n\n\n
GMM plays a key role in drilling. With its help, the direction of wells is determined using magnetic sensors (MWD). This is especially important in fields with an anomalous magnetic field, for example, at Priobskoye and Prirazlomnoye.\u00a0<\/p>\n\n\n
Rosneft has already tested the accuracy of the new model at these fields. The results confirmed its effectiveness. In addition, the conditions for the use of GMM in other territories have been clarified.\u00a0<\/p>\n\n\n
The new Russian geomagnetic model is an important step in improving drilling accuracy. Its implementation will reduce costs and risks in oil and gas production. In the future, the model’s resolution may be further improved, which will open up new opportunities for geophysical research.\u00a0<\/p>\n\n\n
