SYSTEMS AND METHODS FOR PERFORMING RANGING MEASUREMENTS USING THIRD WELL REFERENCING

摘要

Systems and methods for obtaining ranging measurements are described herein. An example method includes injecting a current 115 into a formation from a first borehole 106 to induce an electromagnetic field 120 within the formation. The current 115 may be received at a second borehole 107. The induced electromagnetic field 120 may be measured. The measurements may be taken, for example, from the first borehole 106, the second borehole 107, or another borehole 102 within the formation. The method may also include identifying the location of a third borehole 102 within the formation based, at least in part, on the measured electromagnetic field 120.
