When a well reaches the end of its producing life, operators must safely abandon these wells in accordance with all regulations. Well abandonment typically involves designing a well abandonment program, cleaning the inside of the wellbore, isolating porous formations, removing all downhole and surface equipment and cut and capping the wellbore. Finally, the surface land must be reclaimed to its original state.
Achieving a clean wellbore while minimizing additional fluid loss is imperative in keeping cementing costs low. SECURE Energy Services offers a variety of products that aid in wellbore cleaning and fluid loss. In addition, SECURE’s remediation and reclamation experts provide project management for the surface land reclamation of abandoned wells.
The first step in completion abandonment programs consists of cleaning the wellbore of loose material which could adversely affect the quality of the cementing operation. Greater efficiency in wellbore cleanouts are achieved with viscous fluids that suspend the material and particulate. SECURE has a full line of fluid viscosifiers and other additives for wellbore cleanout operations.
In addition, several fluid loss additives are available.
