The Drill String Design evaluates torque, drag, hydraulics and slip crushing. An optimum drill string design is the one that meets all of the operational parameters, for given drilling constraints and conditions, and considers rig pipe management. The Drill String Design is extremely beneficial in early planning stages, since it evaluates the key factors: planned trajectory, available tubulars, available pump pressure and takes into consideration the efficiency of pipe handling. Subsequent Drill String Designs through the exploration phase and development wells ensure that correct equipment is available and allocated for any design revisions and ensures a smooth transition to completion.
Drill String Design Application:
Deepwater and Extended Reach
Drilling and Sidetrack Operations
Completions and Workover Operations
Difficult Trajectories
Drill String Design Calculations:
Optimizes on critical parameters
Evaluates torque and drag associated with each trajectory
Evaluates a drill string design that will meet mechanical loads to prevent drill string failure
Calibrates the torque and drag model based on the actual drilling parameters
Evaluates operating limits to prevent buckling
Evaluates the load at the slips to prevent slip crushing
Provides pressure drops for different pipe sizes to select the best drill pipe option
Evaluates and optimizes hydraulics for bit hydraulic horse power or jet impact force
Evaluates directional trajectories to reach to TD, for drilling and completions
Evaluates casing wear and side loads
