EM-Measurement While DrillingIntroduction
This is a Bottom-Mounted & Retrievable Positive Mud Pulse MWD system, which can be deployed at the top of the well and retrieved from the bottom of the well. It offers precise measurements and ease of use. The system employs proven and reliable positive mud pulse technology, transmitting standpipe pressure signals and other parameters via wireless communication at the surface, eliminating the need for cables.
