The analysis conducted in this study focuses on the "AB-1" rig's ability to handle calculated loads. Results show that at 1,248 ft MD with 13 3/8" casing, the hook load and drawworks are both 84,864 pounds. At 5,818 ft MD with 9.5/8" casing, these values increase to 273,446 pounds. At 8,463 ft MD using dual 3.1/2 tubing, the load is 159,748.8 pounds. Mud pump power calculations reveal pressures of 681,408 psi for surface sections and 5,632.97 psi for production sections. Casing is a steel pipe inserted into a wellbore to prevent wall collapse, isolate abnormal pressure zones, and provide space for subsurface equipment during hydrocarbon production. This study aims to evaluate the casing load by analyzing hook load, drawworks, and mud pump power. Hook load represents the weight supported by the rig, including the accumulation of pipe weight, casing weight, and drag forces. Drawworks serve as lifting equipment for casing and tubing during drilling operations, while mud pumps circulate drilling fluids to support the process. Based on these findings, the "AB-1" rig is deemed suitable for operations with a hook load and drawworks capacity of up to 500 tons (1,000,000 pounds) and a mud pump pressure limit of 5,787 psi.
