Deliverables and Timing
Accurate assessment of worn casing properties with unique stiff-string and 3D orientated wear models
Multiple wear factors to simulate every type of drill string contact (hardbanding, DP body, DP protector, torque reducer...) on various casing grades
Sensitivity studies on well path, DP range, hard banding, CW mitigation tools, driving system
Tortuosity and dogleg effect (via wellbore surveys, randomized or Local Dogleg Analysis [SM02])
Wear factor calibration based on calliper logs
Includes
Rotating drill string in casing generating wear at various orientations
Reduce risk of well integrity loss at the planning stage and real-time
Find optimum casing design solution in terms of safety and economics
Manage unplanned operations and their impact on casing wear
Avoid expensive work-over or shallow sidetrack operations
Increase ultimate production by enhancing well lifetime
Post-WellReal TimePre-WellBenefits /
Calculate expected cumulative wear depth and orientation in every point of the casing strings
Qualify the casing as a competent safety barrier for the entire well life-cycle
Derive residual casing strength (API collapse, burst, tensile and von Mises tri-axial safety factors)
Verify casing integrity and qualify CW mitigation measures based on calibrated Wear Factor and simulations
Anticipate high levels of wear and design casing string accordingly
