Annotation: A method of data transmission (from bottomhole to surface) on the drilling angles during oil and gas wells drilling. The present methods for data transmission are considered. The advantages and drawbacks of the methods are analyzed. New method for data transmission with using ground-based generator is suggested. As a result of preliminary calculations, the possibility of the suggested method using is shown.
