Version 7 Now Available!!
CWEAR stands alone in the
industry as a powerful engineering tool for calculating and monitoring
the progression of wear due to rotary contact of drill pipe with casing,
riser, and other downhole elements. The extent, magnitude, and location
of wear is calculated as well as its effect on burst and collapse
pressures. This allows you to change operational procedures to reduce
the accumulation of wear before expensive (and possibly catastrophic) problems develop.
The latest version 7 is more powerful and easier to use than ever before (see new features below). The program addresses
wear in both onshore and offshore wells. Features include wear vs.
depth from casing wear logs, comprehensive tubular databases, and
a large database of wear factors (new lab data now included). These wear-factor data capture a
large body of empirical results from measurements in MTI's lab with
a variety of casing/riser and tool-joint materials, fluids and other conditions.

New Features in Version 7
- Algorithms for calculating wear are enhanced, including accounting for wear caused by contact of the body of the drill pipe with casing
- Two sets of Wear History data (current and previous) can be reviewed simultaneously to allow easy comparison of the impact of changes
- Tapered stress joints in the riser string can now be specified
- Database of wear factors measured in lab tests has been enhanced
- Several new viewing tools are provided for the survey
- An enhanced database of drill pipe, drill collars, and casing is included
- A 2D Well Planner utility is available to quickly create wellpath surveys for planning
- Data and parameters can be easily imported/exported to other applications via MTI’s GALAXY database
Standard Engineering Features
- Calculates location & magnitude of wear in casing, riser, and flex joint
- Allows calibration of wear parameters with field wear data
- Calculates burst and collapse pressures for a worn riser & casing
- Analyzes sensitivity to flex-joint offset angle to determine the maximum allowable offset angle
- Predicts required number and placement of drill-pipe protectors
- Unlimited directional survey stations are allowed
- For planning, random and sinusoidal tortuosity can be added to develop surveys representative of real wells
Cost Saving
- Provides a timely warning of possible catastrophic hazards caused by wear in casing, riser, or flex joint
- Enhances operational efficiency
Easy to Use
- Step-by-step problem solving approach
- Complete operational and engineering help provided
- Can link to databases such as DIMS
- Creates MS Office reports
- S.I., Oilfield or mixed units

You can track, review and compare previous and current (predicted) wear history to avoid expensive problems due to wear.
For offshore geometries, the flex-joint offset angle has a significant effect on wear.
Output is presented in a variety of useful formats including the wear cross-section, which can be viewed in detail at any depth of interest.
Burst and collapse are degraded by wear. Strength is shown along the casing/riser string for each wear factor. |
