Water and Sand Control Technology Successfully Applied in Jidong Oilfield: A Case Study

Abstract

In order to solve the growing water production problem of screen pipe completed horizontal wells in unconsolidated sandstone reservoirs, water and sand control screen pipe was developed. By combining swellable packers, installing different sized nozzles, and assorting corollary tools, a water and sand control completion string was formed and then field tests were carried out. The field application shows that water cut of water and sand control screen pipe completed horizontal wells raises much slower compared to conventional screen pipe completed horizontal wells.
