Abstract
The whipstock system has successfully improved on operation efficiencies by reducing the total operational time by up to 50%. This is achieved by the system's ability to bypass the upfront cleanup / gauge run, on site assembly, and limitations on running speed. The absence of personnel in the red zone decreased the associated risk during deployment of the system. Even when met with faulty draw works, poor well conditions, and ovality in the casing the system was deployed without issues. Flawless execution of the system was demonstrated by setting the whipstock on the first attempt. The quality of the window was verified with the passing of a rotary steerable drilling assembly. No additional trips were required to ream or polish the casing exit window.
The mill to whipstock interface delivers on improved safety, robustness, and efficiency of a casing exit operation. This connection provides a positive impact in the reduction of carbon emissions by effectively decreasing the required time to perform a casing exit. The redundant set anchor prevents additional runs due to its redundant activation feature and its ability to be reset and reoriented if required.
This system delivers on improved safety, robustness, and efficiency of a casing exit operation by providing a positive impact in the reduction of carbon emissions. From multiple aspects, decreasing the required time to prepare the well and perform a casing exit.
