Abstract
Summary Long horizontal-section wells are economical requirements for heavy-oil fields in deepwater environments. This article discusses the operational limits for gravel-pack placement in such wells in consideration of the maximization of the horizontal-section extension in low fracture-gradient scenarios. A parametric study on the variables governing the gravel-pack operations indicates that careful hydraulic design and detailed operational procedures can guarantee a successful job. Alternative strategies are proposed to extended hydraulic limits in critical conditions.
