• Cerberus™ for Jointed Pipe

    Cerberus for jointed pipe is a state-of-the-art software used for modeling any operation involving the running of tools, casing or completions into and out of wells.



    By analyzing the cumulative forces acting downhole at each stage of the job, Cerberus is able to determine whether the target depth can be reached, the desired tasks performed and the equipment safely returned to surface.

    Its most important feature is the ability to model conditions in deviated and horizontal wellbores. For continuous wellsite job monitoring and problem detection, Cerberus also runs in real time.

    Cerberus for jointed pipe will help provide answers to many critical questions and may even prevent costly failures and downtime, such as:

    • Can I reach the target depth without buckling the pipe and then return to the
    • surface safely?
    • How do the length, diameter and material properties of my bottomhole assembly (BHA) affect my ability to get past doglegs in my wellbore?
    • How does varying drill collar length or diameter affect weight on bit (WOB) and the location of the neutral point?
    • What is the maximum WOB or set down force for each depth?
    • For each depth, how much pull can be applied to the end of a toolstring before exceeding the yield strength of the pipe?
    • Can I attain my desired WOB while drilling without helical or sinusoidal buckling taking place?
    • How does the actual weight and torque at bit correspond to the surface readings
    • on the rig floor?
    • How much drag reduction can I expect to see from pipe rotation while running in or out of a deviated well?
    • How does viscous drag from fluid circulation or reservoir flow affect the forces and stresses on the pipe?
    • What is the risk of differential sticking?
