Well Engineering Partners provided various services for magnesium brine producing wells owned by Nedmag. An HWO was needed for the wells. Some wells were still in production until the start of the successful workovers which were carried out with the purpose to re-complete the wells with a Dual Concentric Completion. Project planning and engineering, coordination, management, and supervision were carried out by WEP, whereas other companies provided the materials for workover. The operation was carried out while having pressurized caverns, thus floating mud cap technology was applied. Prior to the snubbing operations, wire-line activities were done to inspect pipe conditions and cut tubings at tactic chosen depths.
