Dynamic-Underbalance Perforating Overcomes Environmental Challenges

摘要

Wireline-conveyed perforating in conjunction with well flowback evolved as the preferred method for well completions in the Terra Nova field. A consequence of this approach was the need to flare the well at the mobile offshore drilling unit (MODU) to generate the required underbalance. The full-length paper details how a new approach to perforating significantly reduced the environmental risk associated with perforating, while also reducing rig time required for perforating operations without compromising well productivity/injectivity.
