An operator working offshore Egypt needed a complete gravel pack of a newlydrilled well using best practices in sand control. The reservoir was depleted, and the operator was concerned that a high sea line pressure would cause most of the production to come from high in the reservoir—missing the potential of the lower zone. But in order to effectively treat the lower zone, a sand production problem would need to be addressed. In the lower zone specifically, the operator was seeking to gravel pack while remaining below a very challenging frac pressure, which would require pumping at a lower rate. Normally, conventional proppant that is pumped at reduced rates could settle and cause a premature screenout, failing to pack completely across the entire length of the lateral. In addition to the technical challenges, the operator needed to control costs, and wanted a solution that would treat the lower zone of the well more economically than a conventional approach.

Because of Baker Hughes, a GE company (BHGE), technical and operational leadership in sand control—and because of successful collaborations in the past, the operator asked BHGE about using the TORRENT™ openhole gravel-pack solution, which combines EXCELLPAK™, a premium multipath gravel-pack screen, LiteProp™ 140 ultralightweight proppant, and a reliable gravel-pack system to help achieve 99%+ packing efficiency in one simplified, integrated operation. The LiteProp 140 proppant is engineered to stay suspended during pumping, making proppant transport extremely efficient, with lower requirements on the carrier fluid and an expanded engineering envelope to perform gravel pack operations at lower pumping rates and/or over longer distances. No damaging gels or breaker additives are required, which eliminated the need for specialized blending and pumping equipment, along with the time and risk associated with complex formulation. And long-term packing efficiency is also improved because the gravel-pack does not have to be “broken” once packing operations are complete.
