High Pressure/High Temperature Drilling.  ADTI has significant experience in safely and efficiently drilling high pressure/high temperature (HP/HT) wells, and has assisted in the development of HP/HT well control guidelines in the North Sea, enabling safer methods of dealing with kick/loss scenarios.

Subsea Engineering/Facilities.  ADTI provides a wide range of subsea engineering services, from wellhead design to installation supervision.  ADTI can also addresses subsea architecture design, tiebacks, well startup/operating procedures and well workover planning.  Additionally, ADTI designs and installs minimal facilities, such as caissons and templates.

Completion and Well Testing.  ADTI designs and plans both surface and subsea completions, specifies equipment and services, and supervises operations.  Key skills include wellbore cleanout, coiled tubing operations, HP/HT drill stem testing, acid stimulations, high-rate well testing, and simultaneous commissioning.

Subsea Field and Well Decommissioning.  ADTI designs and plans for decommissioning of Subsea Fields by the development and implementation of efficient suspension and abandonment philosophies and programmes. This work involves the specifying and supervising of Rig and Wellservice vessel intervention services; wellservice activities in well interventions and well clean ups; subsea activities in decommissioning and recovery of subsea infrastructure, subsea wellheads, trees and completions.
