Pesca Pubblicazione scientifica Offshore Well Intersection and Casing Pull Through to Deliver Pipeline Segment FILONE TECNOLOGICO TEMA produzione e cattura RIASSUNTO AbstractDue to technical and logistical challenges, an inovative solution was required to connect two offshore platforms in shallow water to allow gas transit as part of a pipeline network. A primary obstacle to conventional pipeline installation at this location was the presence of a large subsea canyon. As a result, the project team decided to utilize jack-up drilling rigs to drill a conduit and then install casing as a pipeline segment.The project utilized some unusual drilling technologies and unique techniques to deliver the final gas conduit. These included a robust program design for a remote location, large diameter hole opening in horizontal wells, active magnetic ranging to affect wellbore intersection at very low incident angle, and synchronizing two rigs' activities as they latched drill pipe and then pulled casing as a single string. Execution was ultimately successful due to the extensive planning work and diligence of the operations teams, and a number of interesting observations and lessons were captured in the process.
