Long-Term Zonal Isolation for Onshore Gas Wells by Use of a Monobore Cemented Completion

摘要

A cemented completion provides an excellent opportunity for low-cost drilling techniques and simple well designs to reduce well-delivery costs without affecting safety or well integrity.In this concept,the completion is run straight into the open hole and cemented in place.There is no need to run a liner and perform a traditional clean-up.The cement effectively replaces the production packer.Achieving a good cement job is essen-tioi to a successful operation.
