WELL RANGING APPARATUS, SYSTEMS, AND METHODS |
摘要 |
Disclosed embodiments include well ranging apparatus, systems, and methods which operate to acquire a series of electromagnetic field strength measurements from a single sensor at multiple depths in a first well, responsive to an electromagnetic field originating at a second well, via direct transmission or backscatter transmission. Further activities include determining a drilling phase associated with drilling operations conducted in the first well, selecting a sensor separation depth associated with the drilling phase, and calculating an approximate range between the first well and the second well, based on the series of electromagnetic field strength measurements and the sensor separation depth.. Additional apparatus, systems, and methods are disclosed. |
