Well Preparation for Tertiary Production

Problems which become apparent during a conversion from secondary production to tertiary production should be corrected to help ensure success of the proposed tertiary recovery project. Some problems are inherent to secondary recovery and will carry over into the tertiary project. These problems could be tolerated during secondary recovery, but may mean the difference between success and failure for a tertiary program. These problems can be generalized in two basic categories: Restrictions of Injectivity, Unfavorable Injection Profiles. Some processes will be discussed in detail to aid in combating the problems that will be presented in this paper.
