Well Integrity for Abandoned Well Re-entries addresses well integrity and operational risks that accompany the benefits of using an old and abandoned wellbore by providing it a second chance to perform. Re-entering an abandoned well provides new life to an old wellbore by reducing the need for drilling new wells. This, in turn, reduces emissions footprint, drilling waste, and costs for some wells. The book covers well integrity basics, abandoned wells, analysis required for re-entry, potential uses for re-entered wells (including applications for EOR, CO2 EOR with sequestration, natural gas storage, geothermal heat recovery, and much more.) Packed with case studies and tips for practical application, this book provides readers with an understanding of re-entry techniques, pitfalls, and diagnostics to determine well integrity. This novel text digs deep into the process and benefits of re-entering abandoned wells in support of sustainability.
