Evaluation of Frac and Pack Completions and Future Outlook

摘要

Frac and pack introduced in the early 1190's in the Gulf of Mexico has become a well-established completion procedure Aimed at enhancing the productivity of gravel packed wells. The Technique consists of incorporating a "tip screenout" hydraulic Fracturing treatment as part of the gravel packing procedure, thus Stimulating the well. However, published well test data, although Showing generally better productivity than classic gravelpacks, Presents positive skin values indicating near-wellbore damage and Often questioning the existence of a fracture intersecting the well- Bore.
