Uneven distribution of proppants in pert clusters

摘要

Simultaneous creation of multiple fractures through separate perforation clusters has long been a cost-effective method for stimulating vertical and horizontal wells. This limited-entry technique is based on distributing the fluid and proppant within different fractures by controlling the number of perforations in each cluster. While the limited-entry technique provides the planned fluid distribution within different fractures, the same is not true for the proppant.
