Abstract:
A method to guide a drilling path of a second well in proximity to a first well including: applying a time-varying electrical current to a conductive casing or liner of the first well; from the drilling path of the second well, sensing an electromagnetic field generated by the current in the first well, and guiding the drilling path trajectory of the second well using the sensed electromagnetic field.
