摘要：
Method for forming a gravel pack in-situ about a horizontal well in a sandy formation. The gravel pack is formed in two separate steps so that part of the pack will function as a foundation for slidably inserting and supporting the well liner. Thereafter, the remainder of the pack is completed about the liner by introducing a gravel slurry that accumulates on the foundation and about the liner.
