The E-Link Transmitter sends data recorded downhole, to surface, via the formation, by generating a sequence of electromagnetic pulses. MWD data, transmitted up to four times faster than with mud pulse systems, is detected at surface by specialised equipment and antennae.
Description
As part of the E-Link System, the E-Link Transmitter forms a dipole; the upper pole is the main part of the drill string, and the lower pole is the insulated BHA section below the Transmitter. Data is transmitted to surface via a propagation signal which is detected at surface by specialised equipment and antennae. Pump cycles are detected by an integral flow switch which activates the required tool function change and a fall back continuous loop mode provides full redundancy.
Features
- Reliable and consistent signal - ideal for UBD applications (lithology dependent)
