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.

• Examines well integrity principles and determination of integrity on a well that cannot be easily diagnosed
• Evaluates the well integrity necessary to accomplish a successful re-entry of an abandoned well and diagnostics required to determine well integrity
• Provides practical techniques for re-entering, reclaiming, and reusing abandoned wellbores for future use
• Reviews risks and economic and environmental benefits to re-entering and recycling an abandoned wellbore which prolongs productivity and facilitates re-purposing wells to support energy transition
