Gravel packing a 2,400-ft openhole horizontal interval
- Halliburton Energy Services (United States)
A typical economic requirement of most high-cost deepwater development projects is high-initial-rate (> 15,000-B/D oil wells or > 70-MMcf/D gas wells) completions. To achieve these rates from pay sands in this field, 2,000--2,500-ft horizontal completions are used. Conventional openhole horizontal completions have been used in the Gulf of Mexico (GOM) since the early 1990`s. However, the number of failures experienced by some operators has raised questions about the reliability of this type of completion. In deepwater projects, high-rate production and completion reliability present major challenges to operators, and traditional methods of sand control often have not been able to satisfy the changing conditions. The full-length paper presents a solution that combines gravel packing, enhanced downhole-tool capability, and advanced fluid technology to solve sand-control problems. The successful application of the first extended, horizontal openhole gravel packs in the northern GOM proved that gravel packing can be applied successfully to extended horizontal boreholes.
