TELEDRIFT ADVANTAGES

Teledrift speeds drilling by providing almost instantaneous surface recordings of hole deviations without the need for making round trips or running survey tool on wire line.

The unit, which is operated by rig personnel, is a rugged, stainless steel, mechanical device which measures well-bore angle in one-half degree increments and transmits the information to an electronic recorder via mud pulse telemetry. The first patents on mud pulse telemetry were issued for the Teledrift instrument, thus making it the Original MWD.

The Teledrift gives readings in one-half degree (1/2 degree) increments or it can also be configured to measure in one-degree (1 degree) increments. The latter has a tool range of seven degrees (7 degrees) without re-setting the instrument.

The Teledrift tool is a reliable mechanical system, with no downhole turbine or batteries required.  There is no upper temperature limit and the tool is consistently run in wells with bottom-hole temperatures greater than 300°F and has been used in wells with a BHT in excess of 550° F.
