Abstract :
Some finite element techniques for modeling an electromagnetic-based telemetry device known as the EM-MWD (electromagnetic measurement-while-drilling) used in oil fields are described. Results obtained from field tests at the test rig of GTI Gas Research Facility, Catoosa, OK, are compared with numerical results obtained using finite-element methods. The finite element technique used is based on the 2D-Axisymmetric H formulation.
