Combination Fracturing/Gravel-Packing Completion Technique on the Amberjack, Mississippi Canyon 109 Field (SPE 26562)


Hannah et al. described the success of using TSO techniques to increase the frac width on a platform 35 miles SE of Venice, Louisiana. Adoption of frac-pack techniques resulted in substantial improvement early in field development, and "the continuous improvement in well performance ... is attributable primarily to the incremental increase of proppant size from 40/70 to 20/40 mesh."


This paper describes a one-step fracturing/gravel-pack (frac-and-pack) completion procedure conducted on the BP Exploration Amberjack platform beginning in early 1992. This platform is 35 miles southwest of Venice, LA. The first four completions on this platform had an average positive skin values of 21. The goal of the frac-and-pack procedure was to reduce these skins to nearly zero. In total, 24 frac-and-pack operations were performed. Details of the fracture design, prefracture testing, fracture design and execution, and production response and a continuing optimization program are discussed. The fractures were performed with the screens in place with the gravel pack after the fracturing operation. The treatments were designed for the tip screenout technique to create wide fractures and to provide proppant loadings exceeding 8 lbm/ft2.

This paper presents the trend of the declining skin values, along with a discussion of time-dependent skins. The changes in fluids, breakers, and proppants are also presented. The average skin on 14 frac-and-pack completions was 5.3. The average skin on the final eight completions was 0.2.
