This paper describes the "frac-and-pack" completion technique currently being used in the Gulf of Mexico, and elsewhere, for stimulation and sand control. The paper describes process applications and concerns that arise during implementation of the technique and discusses the completion procedure, treatment design, and execution.An innovative well-completion technique, frac and pack, recently has been introduced into Gulf of Mexico well-completion operations. The technique combines the stimulation advantages of hydraulic fracturing with the sand-control technique of gravel packing. The method involves a one-step fracturing and gravel-packing operation performed through conventional downhole gravel-packing hardware.The technique is being used successfully to reduce skin damage effects and to improve the productivity of unconsolidated sandstone completions significantly by creating better communication between the wellbore and the reservoir. An example of the productivity improvement related to frac and pack is provided in the Conclusions and References. Successful fracturing of soft formations poses challenges different from fracturing of typical hard rock. The primary difference is the use of tip-screenout designs and very high sand concentrations to ensure adequate fracture conductivity between the reservoir and the wellbore. Many authors have described tip-screenout fracturing techniques.
