Electromagnetic Telemetry (EMT) Service

The Sperry EMT MWD/LWD system allows data transmission without a continuous fluid column, providing an alternative to negative and positive pulse systems. The system has many applications, including making underbalanced drilling more cost-effective, especially when drilling with air or gasified drilling fluids, in which conventional mud pulse telemetry systems cannot function. However, the Sperry EMT service is not limited to underbalanced drilling. To date, more than 70 percent of downhole runs using the service have been on overbalanced applications where high data density and low survey time are key factors to successful drilling operations.

Electromagnetic Telemetry (EMT) Service

The EMT system establishes a two-way communications link between the surface and the tool downhole. Using low-frequency electromagnetic wave propagation, the EMT system facilitates high-speed data transmission to and from the surface through any formation. Data formats can be readily customized to suit the drilling needs of the particular well.
