Published: 01 November 2009
... for both the longest well, at 40,320 ft measured depth from the rotary table (MDRT), and the longest along-hole departure of 37,956 ft. The use of new techniques allowed existing constraints to be challenged and overcome successfully. These achievements were possible by applying sound engineering...

... then repeated offshore, completing two interventions in a single run. The SSD's were successfully opened at ~12,000 ft MDRT and ~8,000 ft MDRT, respectively while leaving the two adjacent SSD's in the closed position. Results, client objective was 100% achieved using only electric line, enabling the client...

.... The measured depth (MD) of these wells was more than 4500 m (MDRT). Mud weights ranged from 10.9 to 11 lbm/gal in the well while drilling the zone. The length of the liner normally ranged from 1400 to 2300 m. The cement slurry was finalized after conducting numerous tests in the laboratory. A lead and tail...
